Congratulations
You have just purchased the finest hubs available. With proper care and maintenance you will
enjoy many years of the legendary performance you have come to expect from all Chris King
Precision Components. This manual is designed to give you the information needed for the setup,
use, and basic maintenance of your new hubs.
As with all Chris King Precision Components, our hubs are superbly designed and manufactured,
responsibly light, and meticulously finished. Our hubs feature our patented RingDrive engagement
system spinning around a 19.5mm aluminum axle on four sets of precision bearings, all of which
are manufactured in-house. This combination, housed in an elegant aluminum shell, offers the
solid and reliable performance demanded by serious cyclists. Like all of our components, our
ISO hubs are user serviceable.
Cautions
Do not use thread-locking compound on any part of your hub(s) . The aluminum driveshells of
the rear hubs are softer than the steel shells, and we recommend using “spidered”-style cassettes
when possible. Avoid using individual cog-style cog sets with aluminum driveshells. We recom-
mend using our aluminum or Ti cog lock rings when installing 9 and 10 speed drivetrains
for increased thread purchase.
Chris King hubs feature adjustable bearing preload. The bearings should be kept in proper adjustment
for optimum product performance. Do not allow the adjustment to become loose, as this may cause a
loss of performance and could lead to damage to the hubs.
Chris King hubs with two piece axles are designed to be used in conjunction with quick-release
skewers. It is recommended that the skewer develop a minimum of 1100 lbs. of clamping force
when set. For best performance, use skewers with steel shafts. Titanium shafted skewers are
not recommended.
Preparation
Wheel building
Hub dimensions for wheel building are available on pages 20 and 21.
Chris King ISO hubs are designed to work with 13, 14 or 15 gauge spokes. Disc brake wheels must be
laced using at least a 2 cross lacing pattern. As the torque generated by driving the cassette requires
crossed spokes, so does the additional torque on the non-drive side flange generated by the braking action.
Radial lacing your ISO hubs is considered outside of the intended use and will void your warranty.
We will not be responsible for damaged or destroyed hubs, any consequential damages, or any
resulting labor costs due to radial lacing your ISO hub.
ISO Lefty® LD and ISO Lefty® SuperMax wheel builds will require the use of a truing stand Lefty® hub
adapter tool such as Park’s® TS-TA or Cannondale’s® Lefty® wheel-truing dummy axle.
Proper wheel building technique is essential in creating a strong wheel. Wheel building is a skill that
requires proper training and specialized tools and should be done by a trained professional. The
spoke tension on each side of the wheel should be as uniform as possible. Tension should not
exceed 120kgf (1200N).
The hub(s) come pre-adjusted from the factory. The adjustment has been made anticipating spoke
tension and skewer compression. Because of variations in wheel-building practices, a minor adjust-
ment should be performed upon completion of the wheel build. See the appropriate “Adjustment”
pgs. 6 - 14 and check the hub before using.

Frame Preparation
Check frame and fork dropouts to ensure that they are parallel to each other. Use an
appropriate tool made by a reputable bicycle tool manufacturer. Non-parallel dropouts
may damage or compromise the performance of your hub.
Installation and Removal of the rotor
Please follow your brake manufacturer’s specifications for rotor installation and rotor
bolt torque specifications.

Set-Up
• ISO SD & LD Front
• Chris King front ISO hubs are designed to work with 100mm and 110mm fork drop
out spacing. Do not attempt to use your hub with any other dropout spacing. The
two piece axle design (see Fig. 4) is designed for a skewer-type retention device
and must not be modified or altered to accept any type of bolt-on retention device.
Chris King SD (small diameter) hub shells are compatible with both a standard QR
and a 15mm through axle. Our LD ( large diameter) hubs are hubs are designed
to be used in conjunction with 15mm and 20mm thru-axles only. The thru axle
is supplied by the fork manufacturer.
• ISO Lefty® SuperMax, and Lefty® LD Front

systems when using our 1mm Disc Spacer, and SuperMax Lefty® suspension
systems from Cannondale® with the use of our 1mm Disc Spacer and the correct
disc brake caliper adapter.
• ISO 135mm Rear
Chris King rear ISO 135mm hubs are designed to work with 135mm frame spacing. Do
not attempt to use your hub with any other dropout spacing. The one piece axle design
(see Fig. 1, pg. 2) can be used with Chris King FunBolts or with our QR adaptors, which
3

allow for the use of a skewer-type retention device. Additionally, 135 x 10mm and 135
x 12mm hubs are designed to be used in conjunction with 10mm and 12mm thru-
axles only. The thru axle is supplied by the bicycle frame manufacturer or through an
aftermarket supplier. Total axle width is 135mm.
The earlier two piece axle (see Fig. 4) is designed for exclusive use with a skewer-type
retention device and the hub can only be used with FunBolts by replacing the two
piece axle with the one piece axle. Do not modify or alter two piece axle systems to
accept thru-bolt retention devices.
• ISO 142mm Rear

• ISO Single Speed Rear
ISO Single Speed rear hub and cog set-up information can by found on pages 9 and 10.
The grease in your hub will provide optimum performance between 30°-110°F. The
bearings and RingDrive engagement mechanism come lubricated with a specially
formulated low-shear grease. To maintain maximum performance in extreme tem-
peratures see appropriate section under “Lubrication”, pg. 5.
Break-In
Once your new hub is placed in service, some settling may occur. Check adjustment
by attaching wheel into dropouts. Ride for 5-10 minutes, check for play or binding,
and readjust if necessary. Recheck after the first 1-5 hours of riding. Check cog lock
ring on rear hubs after the first 20 hours of use, and tighten if necessary. Continue
monitoring for the first 60 hours of use.
During the first 60 hours of use, above average amounts of drag may be noticed. This
is normal as the seals break in, and will soon diminish. If this causes chain sag while
back-pedaling, increase the B-tension (cage tension) on the rear derailleur.
The bearing grease is intentionally overpacked and excess grease may seep from
the bearing seals during the break-in period.
Maintenance
Maintenance schedule
Chris King ISO Hubs are designed to provide long life and high performance. Beyond
an occasional adjustment, the only maintenance necessary is cleaning, lubricating the
RingDrive (see “The RingDrive”, pg. 15), and re-lubricating the bearings (see “Service
of the bearings”, pg. 17). Riding conditions will determine how often to maintain your
hubs. As a beginning guideline, your hubs should be maintained every 6-12 months
in normal and dry conditions and every 3 months in wet or muddy conditions.
4

The bearings in your new Chris King hubs are of the highest quality. However, all bear-
ings will settle and eventually wear with use. Since looseness or “play” in the bearing
assembly can develop as a result of wear, Chris King hubs have been designed with
an adjustable bearing preload mechanism and any normal play can be eliminated
(see the appropriate “Adjustment” section, pgs. 6 - 14). *Do not ride hub without the
proper preload adjustment
Notes on RingDrive™ maintenance
Normal preventative maintenance of the RingDrive is simple and can be performed using
basic tools (see “The RingDrive”, pg. 15). In many cases, a minor cleaning and reapplication
of lubricant is all that may be necessary. Judging when to perform this basic maintenance is
determined by riding style and conditions. As a guideline, your hubs should be maintained every
6-12 months in normal and dry conditions and every 3 months in wet or muddy conditions.
Annually or if bearing and freewheel drag is noticed or foreign debris is detected in the grease
and/or the grease looks hard or dry, a complete servicing (removal and cleaning) of the
RingDrive should be performed. Complete service includes the removal of the RingDrive
engagement mechanism and requires the use of our Hub Service Tool. See any authorized
Chris King dealer for complete service or you may purchase a Hub Service Tool Kit from your
dealer or directly from Chris King Precision Components. Chris King Precision Components
provides overhaul services at reasonable rates. Contact the Customer Service hotline
at 800-523-6008 for details.
Lubrication
Normal conditions
In normal riding conditions (32°-110°F), our RingDrive grease is recommended for the
bearings and the RingDrive. Do not substitute other brands of grease, as they may
cause premature wear and/or be too sticky for the helix of the RingDrive inhibiting
proper engagement.
Cold conditions
To ensure proper engagement in sub-freezing conditions, first be sure that there is no
water or moisture inside the hubshell. The hub may require an overhaul to ensure that the
hub interior is completely water-free. Then mix the grease in the RingDrive area, especially
on the helical splines of the driveshell, with 5-10 drops of Tri-flow. If you expect to be rid-
ing in temperatures that are consistently at or below freezing replace all internal lube with
a quality 10w synthetic oil. Do not over fill. We reccomend using a siliconal oil (Pedros
®
SynLube or Mobil 1
®
)
Wet conditions
Riding in wet conditions necessitates more frequent service. Often this is as simple as remov-
ing the axle and driveshell from the hub, removing any moisture from inside the hub shell, and
applying more grease to the needle bearing. This should not replace periodic complete disas-
sembly and maintenance, especially in extreme or prolonged wet conditions.
Since it is nearly impossible to seal a hub from water and still have it spin freely, we have designed
our hubs to be able to operate normally with some water intrusion. Although the bearings are stain-
less steel and will resist water induced corrosion, the lubricant will eventually deteriorate, leading to
premature bearing wear and possible failure. High-pressure spray washing, transporting or riding
the bicycle in the rain, or submersion in water while riding can all lead to lubricant contamination
5

by water. Be aware of these situations and service more frequently when they occur.
In a pinch...
If Chris King RingDrive lube in not available, a quality 10w synthetic oil may be substi-
tuted. Do not substitute other brands of grease, as they may be too sticky for the
helix of the RingDrive. Running the hub on oil will cause the RingDrive to be more
audible, yet functionally no different. Since this is a lighter lube than our RingDrive
lube your hub needs to be serviced more often.
If you have any additional questions, please call our Technical Services Department at
800.523.6008, or check out our web site for tech info and videos: www.chrisking.com

The ISO Single Speed rear hub uses our Single Speed one piece axle design. For
disassembly, reassembly and adjustment information, follow the one piece axle in-
structions on pages on pages 10 and 11 of this manual.
Cogs (see Figure 10)
Chris King Single Speed hubs use a cassette-style cog mounting system.
Special splines and lock rings have been designed to accept our premium
quality stainless steel cogs. They are available in sizes from 12t to 20t.
Cogs can easily be removed and changed using standard cassette tools.
Chain
Chris King cogs are designed to be used with an 8-speed or 3/32” chain
only.
Chain line
Setting the single speed cog to the proper chain line is essential to achiev-
ing the best performance from a bicycle’s drivetrain. Our Single Speed rear hub allows
for center-to-cog chainlines of 45, 50 and 55mm. To determine the proper chainline
on a single speed bicycle with 135mm rear dropout spacing, follow these instructions:
1. Determine the front chain ring position by measuring the distance from the
exact middle of the bottom bracket shell to the front chainring.
2. Locate the middle point of the rear ISO Single Speed hub by measuring 67.5mm
from the inside face of the rear drop out to the middle of the hub.
3. From that middle point, use the front chain ring position measurement found
in step 1, and measure from the hub center out to the driveshell.
4. This is the point on the driveshell where the rear single speed cog should be

Further disassembly requires specialized tools. These come individually or in the Chris
King Hub Service Tool Kit, which is available at any authorized Chris King dealer, or
directly from Chris King Precision Components.
Reassembly of two piece axle on rear ISO hub (see Figure 11)
1. Lightly grease threads on adjusting cone and axle end. Apply two drops of
Tri-flow
™
to axle O-ring.
2.
Insert main axle through driveshell. The axle is properly seated when the threaded
end appears through the bearing and the end is flush with the end of the hub shell.
3. If axle end and adjusting cone are assembled as one unit, disassemble by
threading axle end out of adjusting cone.
4. Thread adjusting cone onto the protruding threads of main axle.
5. Thread axle end into adjusting cone until it stops.
6. Proceed to “Adjustment of two piece axle on rear ISO hub”, below.
Note: To improve performance, the axles have been precisely matched with the needle
bearings in the driveshell. Be sure to combine only like numbered parts, (e.g., #3 axle
with #3 needle bearing race).
Adjustment of two piece axle on rear ISO hub (see Figure 11)
The following instructions assume that the driveshell is facing to the right:
1. Insert 5 mm hex wrenches into both ends of the axle assembly. (See page
7 for more info)
2. Hold left hand stationary and turn right hand counterclockwise 1/4 turn until
the assembly is loose.
3. Hold hex wrenches stationary and adjust bearing preload with the adjusting
cone. You may use the hub cone adjusting tool if necessary.
4.
Advance adjusting cone until it contacts bearing. The rear hub takes a slightly
higher amount of preload than “no play”, since some settling may occur while riding.
5. Once preload is set, tighten axle end to 110 inch-pounds.
6. Check adjustment by clamping wheel into frame with quick-release. Ride for
5-10 minutes, check for play or binding, and readjust as necessary. Double
check adjustment after the first 5-10 miles of riding.
Note: Correct adjustment of the rear hub is necessary for proper engagement of the
RingDrive. If the hub is run loose, the RingDrive may not engage properly and could
lead to permanent damage of the internal parts. *Do not ride hub without the proper
preload adjustment

The RingDrive™
Inspection
Having removed the axle and driveshell (as instructed in “Disassembly...” pgs 10
and 11), the RingDrive is accessible through the large side of the hub shell. Visually
inspect the hub’s interior. Under normal conditions the grease should look moist and
may have darkened slightly. A modest film should coat the moving parts.
As with the rest of the hub, the RingDrive is designed to operate with some water
contamination. Water intrusion can usually be remedied with basic maintenance.
However, if foreign debris is detectable in the grease and/or the grease looks hard
or dry, then a complete removal and servicing of the RingDrive is necessary.
Basic maintenance
1. Take a clean, lint free rag and wipe any spent lubricant from inside the hub shell.
Be careful not to drag any dirt or debris from outside the hub into the interior area.
2. Once the interior is clean in appearance, locate the helical splines of the
drive ring about an inch inside the large bearing.
3. Using a toothbrush, pull the bristles across the helix in an outward direction.
Work your way all the way around the inner circumference to remove any
small particles that may be in the spline grooves.
4. Once completed, wipe the area directly in front of the helix to remove any
debris. This method should be used to clean the helix on the driveshell as well.
(If compressed air is available, blow across the helixes in line with the spline
grooves to remove any debris).
With the interior wiped down and the helixes brushed clean, a fresh application of
lubricant should be applied. The RingDrive is designed to work with our specially
formulated low shear RingDrive grease. Do not substitute other brands of grease,
as they may be too sticky for the helix of the RingDrive.
5. Lubricate by reopening a gap between the drive rings, and laying a bead of
RingDrive grease on the teeth between them.
6. Apply a bead of RingDrive grease to helical splines on driveshell. Then apply
a few drops of Tri-flow
™
onto the helical splines and the o-ring of the driveshell.
7. Before reinserting the driveshell into RingDrive area of the hub, the helical
splines must be clean of any debris. *An optional Stainless Steel driveshell
is available for riders who are experience above average wear.
8. Proceed to “Reinstallation of the driveshell assembly”, pg. 16.

Service of the RingDrive™
In addition to the basic maintenance of the RingDrive, a complete removal and servicing may be
necessary. Complete service requires our Hub Service Tool Kit and, as a basic guideline, should
be performed at least once every 12 to 24 months. See any authorized Chris King dealer for
complete service or you may purchase a Hub Service Tool Kit from your dealer or directly from
Chris King Precision Components. Chris King Precision Components provides overhaul ser-
vices at reasonable rates. Contact the Customer Service hotline at 800-523-6008 for details.
In a pinch...
If you need to perform a RingDrive service and don’t have the Hub Service Tool Kit or
cannot make it to a dealer, this method may be used for temporary results:
1. Remove the axle and driveshell to access the interior RingDrive area.
2. Push the drive ring with helical splines inward to open a gap, exposing the
drive teeth and flush the interior with a light solvent-based spray lubricant (e.g.,
WD-40
™
) until the area appears clean. Blow off any remaining solvent until
completely dry.
3. If contamination is still apparent, repeat flushing and blow completely dry. A
complete service of both hub shell bearings should be performed at the same
time. For bearing service information see “Service of the bearings”, pg. 17.
4. Finish by performing the “Basic maintenance”, pg. 15.
5. After assembly, carefully hand test hub for smooth operation of the bearings
and consistent, positive engagement of the RingDrive. If performance is not
improved to original quality, a complete RingDrive removal service must be
performed.
Reinstallation of the driveshell assembly
1. Check the helical splines of the driveshell for any particles or debris before
proceeding; the driveshell must be clean before installing.
2. Apply several drops of Tri-Flow
™
on the helical spline, O-ring, and tapered
diameter directly adjacent the O-ring. Apply a bead of RingDrive lube to the
helical splines.
3. Insert driveshell into hub shell, slowly. As the driveshell enters the RingDrive
area, it will want to mesh the helical splines of the drive ring. As it begins to
mesh, a slight clockwise turning motion of the driveshell will help pull it into
the hub shell. Continue twisting as the driveshell pulls itself into the hub shell.
At the bottom of its inward movement, an audible “click” or “pop” sound
indicates that it has found home and is fully seated. The “click” or “pop” is the
spring retainer popping onto the driveshell and the driveshell seating on the
bearing, indicating the driveshell is fully inserted. Some pushing pressure on
the driveshell may be necessary to pop the spring retainer onto the end of
the driveshell. You can check to make sure the driveshell is properly seated
by checking with your fingers from the non-drive side of the hubshell.
Note: During removal of the driveshell unit the spring retainer plate can become off-
centered. Be sure that the spring retainer is properly centered against the back of the
16

spring area before reinstalling the driveshell. Make sure the o-ring is correctly seated.
4. Test engagement by spinning driveshell in both directions. If it does not engage,
remove driveshell, check cleanliness and reinsert. Retest.
5. The hub is now ready to have the axle
installed.
Service of the bearings
(see figure 11)
Chris King sealed bearings have remov-
able snap rings that hold the rubber seals
in place.
1. Carefully, using a small screwdriver,
pick, or penknife, remove the snap
ring by inserting tool into split of
snap ring. Gently work one end of the
snap ring toward bearing center until
it is out of its groove. Follow the ring around with the tool until the snap ring is
completely dislodged.
2. Lift and remove exposed rubber seal to access the interior of the bearing.
3. Thoroughly flush the bearing with a light spray lubricant (e.g., WD-40™) and
blow dry.
Note: Some solvents, synthetic lubricants, and greases with high-pressure additives
may attack and damage seals and other nonmetallic materials. Minimize exposure
to these substances and thoroughly dry hub after cleaning.
4. Wipe dirt and other contaminants from the seals and snap rings. Avoid
cleaning the seals with solvent, which could cause deterioration.
5. Lay a bead of our RingDrive grease (see “Lubrication”, pg. 6), filling the gap
between the inner and outer races 3/4 the way around bearing. Do not
overfill bearing with lube, as this may cause excess drag. Rotate the inner
race to work grease throughout the ball area.
6. Reinstall black rubber seal between inner and outer bearing race. If using the
original seal, reinstall using the same orientation as when they were originally
installed, as this will minimize drag.
7. Insert one edge of snap ring into groove of outer bearing race. Press along
entire groove until snap ring is fully seated; a small gap should be visible
between both ends of the snap ring.
8. Turn inner race of bearing by hand to test for binding. If bearings do not run
smooth, repeat steps 1-8. Binding is often a result of improperly seated seals
and/or snap rings.
Used snap rings and seals can be reinstalled unless warped, punctured, or otherwise
damaged. If damaged, replacement seals and snap rings are available from any
authorized Chris King dealers or directly from Chris King Precision Components.

Universal Disc Brake Rotor Adaptors
Brake rotor adaptors are used on Universal Disc front and rear hubs to accommodate
ISO and other disc brake systems. These various adaptors are offered in different
widths to correctly position disc brake rotors. Be sure to use the adaptor designed
for your brake system. Do not attempt to modify your adaptor to work with rotors
other than those for which they were designed. Mount the brake rotor according to
manufacturer’s instructions. Rotor mounting bolts should thread 8mm into the rotor
adaptor and must not extend through the brake rotor adaptor or contact the hub.

Installation of rotor adaptor (see Figure 12)
Before installation, thoroughly clean both the brake rotor adaptor and the splines on
the hub shell. Any debris on the splines may not allow the rotor to run true, inhibiting
the performance of the brake.
1. Apply a light amount of grease to rotor adaptor bolts. Do not use Loc-Tite™ or
other sleeving compound to secure rotor adaptor.
2.
Place the adaptor onto the splines. When snug, the adaptor should leave an even
gap approximately the width of a piece of paper between the hub and the adaptor.
3. Insert the three bolts provided. In an alternating pattern, hand tighten adaptor
bolts to pull adaptor down evenly.
4. Using a 3mm hex wrench, finish torque to 28 inch pounds. Do not over tighten.
Removal of rotor adaptor (see Figure 12)
1. Remove the disc brake rotor if it covers the three mounting bolts.
2. Remove the three adaptor mounting bolts using a 3mm hex wrench.
3. To remove the rotor adaptor from the tapered splines, pry between the adaptor
and the hub using two opposing plastic tire levers (it should pop off easily). Do
not use metal objects, such as screw drivers, to release the adaptor.
