Please be advised that many bicycle service and repair tasks require specialized knowledge, tools and
experience. General mechanical aptitude may not be sufficient to properly service or repair your bicycle
and/or Reynolds wheels. If you have any doubt regarding your service or repair ability, please take your
bicycle to a qualified mechanic or an authorized Reynolds dealer/distributor.
INTENDED USE
• Useofroadwheels: For road racing or general cycling on smooth, dry road surfaces only.
Not intended for use on motorized vehicles or for use on vehicles carrying more than one
operator/rider.
• Useofmountainwheels: Only use on open, and approved, trails and public lands.
Not intended for use on motorized vehicles or for use on vehicles carrying more than one
operator/rider. Any such use constitutes misuse which will void the Reynolds warranty and
may result in an accident, serious personal injury, death or property damage.
COMPONENT WEAR INSPECTION REQUIREMENT
The longevity of your Reynolds wheels depends on many factors. Factors that will determining their
longevity are: rider size and riding style, environmental conditions, tire specifications and air pressure, terrain
and geography, cleanliness and maintenance, brake pad composition, and impacts or falls. Improper or
harsh use may also compromise the structural integrity and significantly reduce the lifespan of your wheels.
Some components of the wheels are subject to wear over time and are not covered under warranty because
this is not due to defect. These items not covered under warranty due to normal wear and tear include:
bearings, brake pads and rim braking surface. Use only Reynolds recommended brake pads. Perform routine
maintenance and cleaning on brake pads and braking surface of rim.
Forcareandusagerecommendations,seeSection8ofthismanualorrefertotheReynoldswebsiteat
www.reynoldscycling.com/maintenance.
Have your wheels regularly inspected by a qualified mechanic for impact and stress marks, cracks,
deformations, and signs of fatigue or wear. If the inspection reveals any damage, no matter how slight,
immediately replace the component. Components that have experienced excessive wear also need
immediate replacement. Frequency of inspection depends on many factors; see Section 8 of this manual
for further assistance. Contact your authorized Reynolds dealer/distributor for suggested inspection/
maintenance schedule that is best fit for your use, riding style and conditions. If you weigh 82kg/180 lbs or

1. TECHNICAL SPECIFICATIONS
PRE-RIDE SAFETY CHECK
• Always wear a helmet when riding a bicycle. See the owners manual that came with your bicycle
for additional safety recommendations and mechanical warnings.
• Check to see that all quick release levers, nuts and bolts are properly adjusted. See the “Quick
Release” instructions in Section 6 of this manual. While bouncing the bike on the ground, look and
listen for anything that may be loose.
• Be sure that your tires are properly inflated to the correct pressure and that there is no damage to
the tread or sidewall.
• Be sure that none of the spokes are damaged, loose or missing. Make sure there also is no
deformation, cracks or sign of fatigue or stress on the rims.
• Be sure that the wheels are exactly centered in both frame and fork. Spin wheels to be sure that
they do not wobble up and down or side to side, and that there is no contact with brake pads
during rotation.
• Check your brake pads and cables to be sure that they are in good condition and free of debris.
• Test your brakes prior to your ride to ensure that they are operating properly.
• Check reflectors and lights to ensure that they are clean, straight, securely mounted and
operating properly where require by law. Reynolds wheels do not include reflectors.
Proper reflectors meeting the Consumer Product Safety Commission (CPSC) regulation should be
installed if bicycle will be used on public roads.
• Learn and follow the local bicycle laws and regulations, and obey all traffic signals, signs and
laws while you ride.
WARNING: Do not ride your bicycle if it does not pass the pre-ride safety check listed above.
Correct any deficient condition(s) before you ride.
GENERAL SAFETY RECOMMENDATIONS
• Always wear a properly fitted and fastened bicycle helmet that has been approved by
ANSI or SNELL.
• Be sure that the periodic maintenance is strictly followed (see Section 8 of this manual).
• Always use original Reynolds, or Reynolds-approved replacement parts.
• DONOT make modifications to Reynolds wheels. Modification, improper service, alteration or use
of aftermarket parts voids the warranty and could cause wheel malfunction resulting in an accident,
injury or death.
• Components that are bent, cracked or otherwise damaged in an accident or as a result of impact
must not be straightened. They must be replaced immediately with original Reynolds parts.
• Wear clothing that will make you visible to traffic such as neon, fluorescent or other bright colors.
• Avoid bicycle riding at night. It’s harder to see obstructions on the ground as well as be seen by
traffic once it becomes dusk. If you do ride at night, you should equip your bicycle with headlights,
taillights and reflectors, as required by law.
• When riding in wet conditions, the stopping power of your brakes is greatly reduced and the
adherence your tires have to the ground is considerably reduced. Your braking power may also
vary sharply, due to the progressive drying of the braking surface during brake use. This will make
it harder to predict performance and control of your bicycle, making it harder to stop. When riding
your bicycle in wet conditions, use extra caution to avoid an accident.
• Please get in touch with your local dealer/distributor, or contact Reynolds directly with any
questions, comments or concerns.

3. CLINCHER TIRES
WARNING: CLINCHER RIM/TIRE COMPATIBILITY
All Reynolds rims are built in strict accordance with E.T.R.T.O. specifications, and are very
dimensionally precise. If a clincher tire is too easy to install on a Reynolds rim, that tire is
probably too big and will not seat properly on the rim, which constitutes a significant safety
concern. Use only high quality clincher tires that require use of tire levers and reasonable
installation effort. Using a tire that fits loosely on the rim can cause unexpected tire failure
resulting in an accident, injury or death.
• The clincher wheel you have purchased is designed to use clincher tires only.
• Before installing the tires, cover the exposed spoke holes in the tire bed using Reynolds supplied rim
strips.
• Ensure that the tire and wheel are compatible in accordance with E.T.R.T.O. standards before
installing the wheel. Check that the diameter indicated on the tire is 622 and that the cross section is
between 23mm and 25mm, mountain tire diameter indicated should be 559 and the cross section is
between 32mm and 60mm (1.25˝–2.35˝).
• Use inner tubes with a long valve stem (at least 43mm), or Reynolds supplied valve extenders.
WARNING: Failure to properly install the tire can cause sudden and unexpected loss of tire
pressure, resulting in an accident, injury or death.
INSTALLING CLINCHER TIRES
Be sure that you do not damage, scratch, crush or otherwise distort any portion of the rim when installing
the tire. Use only plastic or nylon tire levers when installing.
• Before installing tires onto new Reynolds wheels, take note of the serial numbers located in the
tire bed opposite the valve stem hole. These serial numbers are required to register your Reynolds
Cycling warranty or RAP.
• Confirm installation of Reynolds supplied rim strip onto tire bed.
• Install one side of the clincher tire into the tire seat provided on the rim (Fig.1).
• Slightly inflate the inner tube to facilitate assembly.
• Toinatethetire: remove the valve cap, unscrew the presta-valve and inflate tire using a
compressor or pump with a pressure gauge to obtain the required pressure. Tighten the valve and
replace the cap.
• Insert the valve stem through the hole in the rim, and position the remainder of the partially inflated
inner tube inside of the tire, between the tire and rim seat (tire bed).
• Install the second side of the tire into the rim seat.

ReynoldsCycling.com 4
• To properly set the tube and tire onto the rim, inflate the inner tube to between 2-3 atmospheres.
Next, manually set the tube and tire on the rim, ensuring that the tire bead is evenly positioned
around the outside circumference of the rim. Make sure that the tube is correctly positioned
within the tire and that the tire is correctly positioned onto the rim. Lastly, inflate the tube fully
to the correct pressure. Please inflate the tube slowly, making sure that you maintain the correct
positioning of the valve stem, tube and tire on the rim.
• Todeatethetire: remove the valve cap, unscrew the presta-valve, press and hold down the valve
core to obtain required pressure. Tighten the presta-valve and replace the cap.
WARNING: Check that the clincher rim shows no sign of significant wear, contamination, damage
or deformation along the sidewall or brake track. This could cause the rim to unexpectedly break
resulting in an accident, injury, or death.
WARNING: Never exceed the maximum inflation pressure recommended by the tire manufacturer
for the cross section of the clincher tire that you are using. See the “Opearting Pressures” table in
Section 9 of this manual. Excess tire pressure reduces the tire’s grip on the road and increases the
risk of the tire unexpectedly bursting. Inflation pressure that is too low reduces tire performance
and increases the probability of sudden and unexpected loss of tire pressure. In addition,
premature wear and damage to the rim may occur. Incorrect tire pressure could cause tire failure
or loss of control of the bicycle resulting in an accident, injury or death.
WARNING: Replace the wheel when the distance between the shoulders/hook beads of a road
rim is greater than 15mm mountain rim greater than 17mm (Fig. 2). A deformed rim may cause
the clincher to suddenly fail resulting in an accident, personal injury or death.
4. TUBULAR TIRES
WARNING: TUBULAR RIM/TUBULAR TIRE COMPATIBILITY
All Reynolds rims are built in strict accordance with E.T.R.T.O. specifications, and are very
dimensionally precise. Use only high quality tubular tires, tubular tire glue and follow
manufacturer’s recommended installation procedure. Take your time and use extra care to
ensure correct installation of the tire and glue onto the rim. Tires that lack sufficient glue bond,
fit loosely on the rims, have defective base tape, are improperly installed or ridden before glue
has sufficiently dried, can cause unexpected tire failure or separation from wheel resulting in an
accident, injury or death.
• Before gluing and mounting tires to your new Reynolds wheels, take note of the serial numbers
located in the tire bed opposite the valve stem hole. These serial numbers are required to register
your Reynolds Cycling warranty.
• The tubular wheel you have purchased is designed to use 28˝ X 22mm diameter tubular tires.
• Before fitting the tires, check that the diameter indicated on the tire is 633/28˝ and that the cross
section is approximately 22mm to ensure that the tire and wheel are compatible in accordance with

ReynoldsCycling.com 5
E.T.R.T.O. standards. Before installing tubular tires, carefully read and fully understand tire gluing
instructions provided in this manual.
• Use tubular tires with a long valve stem (at least 43mm) or Reynolds valve extenders.
WARNING: TUBULAR TIRE INSTALLATION
Failure to properly install tubular tires can cause sudden and unexpected loss of tire pressure or
separation of the tubular tire from the wheel resulting in an accident, injury or death.
• Gluing tubular tires is multi-day procedure requiring specific mechanical skills and an attention
to detail. Closely follow the instructions provided in this manual for gluing tubular tires to your
Reynolds wheels. Follow tire manufacturer’s instructions to prepare tire prior to gluing.
• Carefully follow the steps in specific order to properly glue tires.

REQUIRED TOOLS
• Truing or similar stand to hold wheel during glue application. Use rags to protect stand from
glue drips
• Acid brush or similar
• Acetone and clean cotton rags (it is safe to use acetone on Reynolds carbon rims)
• Floor pump
• Latex gloves
• 120 grit sandpaper or emery cloth
• Tubular glue/rim cement. We recommend using Vittoria, Continental, or Challenge
tubular cement.
Carefully read the instructions on the label for drying times and other useful tips.
PREPARATION
• Begin the day before you plan to use your wheels for the first time (24 HOURS). Place your new
tubular tires on the set of corresponding tubular wheels.
• Inflate the tires to within 10-20 psi of their max pressure. This will help stretch the tire, making it
easier to install once glue has been applied.
• To inflate the tire: remove the valve cap, unscrew the presta-valve and inflate the tire using a
compressor or pump with a pressure gauge to obtain the required pressure, tighten the presta-valve
and replace the cap.
• After stretching the tires for a day you are ready to begin gluing. Be sure to have all of your tools set
out and easy to access. Work in a well ventilated area. Keep glue, acetone and sharp objects out of
the reach of small children.
• Remove the tires from the rims and place them aside. It is recommended that you wear latex gloves
during the gluing process.
• Abrade the tubular tire bed using 120 grit sandpaper/emery cloth; starting at the valve hole, sand
around the circumference of the rim. Lightly sand the entire tire bed. This procedure creates a
tactile surface for glue adhesion and aids in removing any mold release left on the carbon rim during
production or contamination from handling.
• Apply a light amount of acetone to a clean cotton rag. Starting again at the valve hole, wipe the
entire rim’s tire bed until no carbon residue is visible on the cloth.

ReynoldsCycling.com 6
GLUING RIMS AND TIRES
• Prior to installing tubular tires onto wheels, you will apply two thin coats of glue to both the rims
and tires.
• Place the front wheel in the truing stand. Begin at the valve hole by applying a small amount of glue
from the brush onto the rim’s tire bed. Brush the glue until complete coverage is achieved across the
width of tire bed. Continue around the circumference of the wheel applying a thin layer of glue
(Fig. 7).
• Allow glue to dry. Repeat this gluing step on the front wheel a total of two times; applying thin
layers of glue with complete coverage across tire bed surface. Follow same gluing steps for the rear
wheel. Set both wheels aside to allow glue to completely dry and move to gluing the tires.
• Inflate tire until inverted; the base tape will roll over to the outside, becoming exposed and
facilitating gluing.
• Starting at the valve stem and working 360 degrees around the tire, apply a thin layer of glue to the
base tape until complete surface coverage is achieved—similar to the technique used to apply glue
to the rims.
• Allow first layer of glue to dry and repeat, adding a second layer to the base tape. Repeat gluing
process on the other tire.
• Do not start mounting new tires until the glue has fully dried. See glue manufacturer’s suggested
drying times, which usually ranges from a few hours or overnight.
INSTALLING TUBULAR TIRES
• Apply one final layer of glue to the rim’s tire bed surface on both front and rear wheels.
This final layer of glue will facilitate tire installation and “true up” of tire to the wheel.
• Place the front wheel at your feet on a clean, dry surface (like a linoleum floor). With the valve-hole
facing up, use the same technique used during the preparation process, referring to the illustration
(Fig 8). Deflate the tire and slip the valve into the rim. Grab the outside of the tire to the right and
left of the valve hole and slide the tire onto the rim bed in a smooth, downward motion, stretching
the tire as you go (Fig. 9). Continue working the tire onto the wheel in the slowly downward
direction until there are only a few inches of tire remaining unseated. Pick up the wheel up and work
the remaining tire onto the rim using your thumbs (Fig. 10).
• Now it’s time to center the tire on the wheel, you must work fast to avoid the glue drying too quickly.
Place the wheel in a truing stand and rotate slowly. While the wheel rotates, inspect the base tape
on the side of the tire near the outer diameter of the rim. The amount of base tape exposed at the
outer edge of the rim should be equal on both sides of the tire. True up the tire by twisting it
side-to-side on the rim. Check that the valve stem is centered and straight in the valve hole.
• Inflate the tire close to its recommended pressure. Check the base tape again to make sure it is
centered and equal in height on both sides of the tire. Also check the tire’s “true” by inspecting the
center of the tread pattern for smooth and symmetrical appearance as the tire rotates.
• Check to make sure that there are no glue deposits on the braking surface or sidewall of wheel.
Use acetone and a clean rag to remove residual glue.
• Set the freshly glued wheel aside for roughly 24 hours to fully cure.
• Repeat this final step in its entirety on the rear wheel and tire.

ReynoldsCycling.com 7
BEFORE YOU RIDE
• Wait 24 hours before riding freshly glued tubular tires.
• With tires inflated, inspect both front and rear wheels for safe glue bond and proper tire adhesion.
Take the front wheel in both hands. Applying pressure sideways to the tire with both thumbs, try
to roll the tire off the rim using a moderate amount of force. Continue testing adhesion around the
circumference of the wheel. Repeat process on rear wheel. If tires hold securely to wheels, verify tire
pressure, install onto bicycle and ride safely.
• If tire adhesion is insufficient, do not ride. Repeat gluing process from beginning or contact your
mechanic, authorized dealer/distributor or Reynolds directly for direction and recommendations.
• Be sure that you do not damage, scratch, crush or otherwise distort any portion of the rim when
installing the tire.
WARNING: Check that the side of the tubular rim shows no sign of significant wear,
contamination, damage or deformation on the sidewall or brake track. This could cause the rim to
unexpectedly break resulting in an accident, injury or death.
WARNING: Never exceed the maximum inflation pressure recommended by the tire manufacturer
for the cross section of the clincher tire that you are using. See the “Opearting Pressures” table in
Section 9 of this manual. Excess tire pressure reduces the tire’s grip on the road and increases the
risk of the tire unexpectedly bursting. Inflation pressure that is too low reduces tire performance
and increases the probability of sudden and unexpected loss of tire pressure. In addition,
premature wear and damage to the rim may occur. Incorrect tire pressure could cause tire failure
or loss of control of the bicycle resulting in an accident, injury or death.
5. CASSETTE INSTALLATION
WARNING: Always wear protective gloves and glasses when working on cassette and cogs.
Always tighten cassette lock ring to manufacturer’s recommended specification.
• Shimano 10 speed cassette systems require a single 1mm spacer installed behind the largest cassette
cog on all Shimano 9/10 speed hubs (Fig. 3).
• Install individual or preassembled spacers and cassette cogs onto cassette body of the hub by
aligning the spline patterns.
 —InstallationofSRAM/Shimanocassette: locate the widest spline on cassette cog and match it with
the widest groove on the cassette body. The profile of the cassette body ensures automatic cassette
cog alignment since there is only one installation option (Fig. 4).
 —InstallationofCampagnolocassette: locate the narrowest spline on cassette cog and match it
with the narrowest groove on the cassette body. The profile of the cassette body ensures automatic
cassette cog alignment since there is only one installation option (Fig. 5).
• Apply grease/lubricant to lock ring threads located inside outer edge of cassette body.

ReynoldsCycling.com 8
• Use a torque wrench to properly tighten cassette lock ring into place. Tighten Shimano and SRAM
lock rings to 40Nm; and Campagnolo 50Nm. Always use correct lock ring tools (Fig. 6)
NOTE: Tools supplied by manufacturers may not be compatible with Reynolds wheels. Always check
with your mechanic, authorized dealer/distributor, Reynolds directly or the tool manufacturer to
insure compatibility before using tools supplied by one manufacturer on wheels or components
supplied by another.
WARNING: Failure to insure compatibility between tools and wheels/components could result in
improper operation or the failure of the componenet, and accident, injury or death.
6. USING THE QUICK RELEASE
WARNING: Reynolds Quick Release (QR) skewers are designed and manufactured solely for
fixing a commercially manufactured quick release hub to a commercially available bicycle frame
or fork.
• DONOT make modifications to Reynolds QR skewers. Any modification, alteration or misuse of QR
is considered as not in conformance and is strictly prohibited, voids the warranty and could cause
wheel malfunction resulting in an accident, personal injury or death.
• DONOTUSE tools to operate QR. Installing and removing, as well as opening and closing QR should
always be done by hand.
• DONOTUSE your Reynolds QR skewers in combination with bicycle trailer.
• Verify wheel centering position, adjustment and tightness of QR onto frame and fork.
Also check skewers for damage (damaged threads, bent/deformed components, cracks and
corrosion). DONOTUSE QR if you are in any doubt of its intact state.
• Install the QR with shorter axle to the front wheel hub.
• The axle nuts (1) of either QR are located on the right–hand side (Fig 12).
• The smaller diameter of the centering spring (2) must face toward the hub.

7. BRAKES
WARNING: Failure to use recommended brake pads will void the warranty on your carbon
wheels, and may also cause wheel component failure, resulting in an accident, injury or death.
• DONOTUSECORKBRAKEPADS on Reynolds carbon wheels. This will void your warranty.
Use only Reynolds supplied or recommended brake pads on your carbon wheels for best
performance. Reynolds brake pads are less subject to overheating and dissipate heat better that
stock brake pads.
• CAUTION: Using the same set of brake pads for both carbon and alloy wheels will increase the
opportunity for excess wear, rim damage and heat deformation on the carbon wheel.
Please consult the instruction sheet supplied by manufacturer.
8. PERIODIC WHEEL AND BRAKE PAD MAINTENANCE
After using the wheelset for the first time, check each wheel for trueness and circularity.
MAINTENANCE AND WHEEL CLEANING
Your Reynolds carbon wheels possess some of the best components and materials available in the cycling
industry. Your rims have a specially engineered composite layer at the brake track area to help dissipate
heat, increase durability and extent longevity. For best results, keep brake pads and rims clean from debris
and glazing on a regular basis.
• Debris can come from many sources. It is commonly generated any time you apply brake pads to
the rim, whether you are riding aluminum or carbon wheels. Both surfaces naturally wear on each
other and remove minute amounts of surface material at the point of contact. Debris is also picked
up from the road and environment as you ride. It is not uncommon to see small stones, metal or
other road debris embedded in bicycle brake pads. Wet and adverse climate riding conditions also
increase debris build-up on pads, contaminant build-up on the rim surface and increased abrasion
between pads and rims.
• Brake pad glazing most often occurs from overheating the brake pad and rim surfaces. Carbon and
aluminum rims react differently to heat. Carbon rims tend to build up heat more rapidly under hard
and prolonged braking conditions. Brake pads may glaze-over or surface-harden easily, especially
if you are new to riding carbon wheels and in hilly or mountainous areas. Riding and braking style
is also a contributor to pad glazing. For most riders, a simple change to their frequency and force
of braking may reduce brake pad glazing and heat build-up. The biggest difference in riding wheels
with aluminum or carbon braking surfaces is the impact of prolonged braking on rim longevity. Try
not to “drag” or “grab a handful of brakes” when slowing your bike with carbon wheels—especially
on long descents.
• Use your brakes with lighter modulation. Try to “feather” the brakes rather than to “ride or drag” the
brakes continuously against the rim. More frequent, short, quick, light applications of your brakes will
offer the best results while still providing adequate stopping power; much like an ABS system does
for your car. Prolonged application of the rear brake combined with shorter, faster, lighter application
of the front brake may also provide less glazing, increase brake pad life and benefit safety in bike
handling.
FOR BEST RESULTS, PRACTICE THE FOLLOWING SIMPLE CLEANING TIPS
• Wheel cleaning may require you to remove the tires to easily access the entire braking surface.
Routine rim and brake pad cleaning should be performed at least every 3–4 months. Contact your
mechanic, or an authorized dealer/distributor for recommended maintenance schedule.
• Suspend your bicycle in a rack and drop the wheelset out of the frame.
• Inspect the brake pad surfaces, front and rear, for embedded debris. Remove any embedded small
particles in the pads with a fine point tool.
• Abrade/scuff/sand the brake pads vertically—opposite the direction of rotation from the wheel. Do

ReynoldsCycling.com 11
this until the pad surface is flat/non-shiny. Use an abrasive tool such as a clean metal file or
80–100-grit sandpaper to abrade the brake pad surfaces.
• Run your fingers along the entire circumference of the wheel’s brake surface feeling for changes in
roughness. Inspect the braking surface for visible contamination or brake pad
build up.
• Use a clean red scotch-brite pad and acetone to best clean the braking surface on your wheels. We
recommend that you wear latex gloves whenever using Acetone. DONOTUSE ACETONENEAR
OPENFLAME. Acetone is highly flammable. Use only in well ventilated area.
• CAUTION:the red abrasive pad will scratch and damage decals. DONOTUSE red abrasive pad on
sidewall fabric of DV3K wheels. Wash Reynolds DV3K fabric wheels by wiping them down with water
and neutral soap, or specific products designed for cleaning bicycles.
• Clean the brake track only. Lightly abrade the brake track, the top 13mm along the outer edge of the
rim circumference. Remove all discoloration, smears and “tacky-feeling” areas. Focus on the rough
feeling areas and those with obvious discoloration. Beginning at the valve hole, very lightly scuff
the entire brake track with the abrasive pad. Clean only in the direction of wheel rotation, along the
circumference of the rim.
• CAUTION:Do not to use excessive pressure when cleaning your wheels as it is easy to remove more
than surface contamination and damage the braking layer molded into rim.
• You will detect dark grey/brown dust accumulating on your abrasive pad. Rotate the pad to a clean
section and continue cleaning. Clean brake track on both sides of both wheels.
• Wipe down the rim surface with a small amount of acetone on a clean cotton rag. You may need
to wipe down the rim several times until you no longer see dark grey/brown deposits on your
cleaning rag.
• You may wipe down the entire rim surface with Acetone; it will remove most-all road grime and oil
Deposits from your hands, but should not damage decals.
WARNING: Using wheels that have not been centered properly or have broken or damaged
spokes may result in an accident, injury or death.
• After every ride check the condition of the tires and inflation pressure.
• Periodically take your bicycle to a qualified mechanic to lubricate the hubs, check spoke tension, and
inspect rim and brake pads for excessive wear. Check with your mechanic to select a schedule that is
best for you (approximately every 2,000–5,000 km or 1,200–3,000 miles).
• Every 10,000–20,000 km (6,000–12,000 mile) you should take your bicycle to a qualified mechanic
to lubricate, remove, disassemble and check the hubs.
• Periodically have a qualified mechanic verify the quality of every component that is susceptible to
wear including rims, spokes, bearings and brake pads. And, if necessary, replace worn and damaged
components with original Reynolds replacement parts.
• At least once a month, please take your bicycle to a qualified mechanic to check the tension of the
spokes, wheel centering, wheel dish and correct as necessary.
• Periods and riding distances are purely indicative and may be significantly different in relation to
conditions of use and the intensity of your activity (for example: racing, rain, salted winter roads,
rider weight, terrain, etc.). Check with your mechanic to select a maintenance schedule that is best
for you.
NOTE: Never spray your bicycle with water under pressure. Pressurized water can pass bearing seals and
enter into components of your Reynolds wheels causing damage beyond repair. Wash your bicycle and
Reynolds wheels by wiping them down with water and neutral soap or specific products designed for
cleaning bicycles. Routine scheduled cleaning of your wheelset and brake pads will improve modulation and
braking in all conditions.
TRANSPORT AND STORAGE
When transporting your Reynolds wheels separately from the bicycle or if the wheels will not be
used for a long period of time, store them in a wheel bag to protect against impact and damage.

9. OPERATING PRESSURES
Never inflate a tire beyond the maximum pressure marked on the tire’s sidewall. Exceeding the
recommended maximum pressure may blow the tire off the rim, which could cause damage to the
bike and injury to the rider and bystanders.
