Warning
Like any sport, bicycling involves risk of injury and damage. By choosing to ride a bicycle, you assume
the responsibility for that risk, so you need to know—and to pracce— the rules of safe and
responsible riding and of proper use and maintenance. Proper use and maintenance of your bicycle
reduces the risk of injury or death.
All bicycles should be assembled and maintained by an authorized bicycle mechanic. If you are not
qualied to assemble, inspect, and maintain your bicycle, please visit your favorite local bike shop or
contact Spot for a referral to a qualied bicycle technician in your area.
This guide covers the details specic to your Living Link™ suspension frame. It does not address
complete bicycle assembly, ng, inspecon, maintenance, or riding techniques. Please refer to the
Spot Brand Bicycle Owner’s Manual for further details.
Under no circumstances shall Spot Brand LLC be held liable for direct, incidental, or consequenal
damages, including, without limitaon, damages for personal injury property damage, or economic
losses, whether based on contract, warranty, negligence, product liability, or and other theory.
A Note on Intended Use
The American Society for Tesng and Materials (ASTM) has established a classicaon standard
for bicycle use, outlined in document ASTM F2043. It is important to use any bicycle within its
intended use classicaon to ensure rider safety, equipment longevity, and warranty coverage.
The Spot Mayhem 130 mountain bikes are classied within Level 3 of this standard:
1This is a set of conditions for the operation of a bicycle on a regular paved surface where the
tires are intended to maintain ground contact.
2This is a set of conditions for the operation of a bicycle that includes Condition 1 as well as un-
paved and gravel roads and trails with moderate grades. In this set of conditions, contact with
irregular terrain and loss of tire contact with the ground may occur. Drops are intended to be
limited to 15cm (6") or less.
3This is a set of conditions for operation of a bicycle that includes Condition 1 and Condition 2 as
well as rough trails, rough unpaved roads, and rough terrain and unimproved trails that require
technical skills. Jumps and drops are intended to be less than 61cm (24").
4This is a set of conditions for operation of a bicycle that includes Conditions 1, 2, and 3, or
downhill grades on rough trails at speeds less than 40 km/h (25 mph), or both. Jumps are in-
tended to be less than 122cm (48").
5This is a set of conditions for operation of a bicycle that includes Conditions 1, 2, 3, and 4; ex-
treme jumping; or downhill grades on rough trails at speeds in excess of 40 km/h (25 mph); or a
combination thereof.

Climb/Lockout Lever
• 3 posions– Open, Medium, Firm
• Spot recommends leaving the lever in the
open mode at all mes, including
climbing, due to the eciency of Living
Link. Locking the suspension for climbing
will only make the ride bumpy!
Compression Damping “Open Mode Adjust”
• 3 posions– 1,2,3
• Increases rmness and support on the
compression (downward) stroke of the shock
• Li and turn black dial to adjust
• Aects “Open” seng on blue lever only
• 1—soest, best for lighter riders, less
aggressive riding
• 3—rmest, best for heavier riders, more
aggressive riding
Air spring pressure
• Use included shock pump to increase/decrease
air pressure
• Sets sag / “ride height”
• Spot recommends starng by seng the rear
shock air spring pressure to 85% of your riding
weight (with helmet, pack, gear, etc.) in
pounds. For example, if you weigh 180lbs ready
to ride, you would inate your rear shock to
0.85 X 180 = 153psi.
• Increase pressure (up to +25psi) if you are
booming out frequently. If adding air pressure
does not prevent frequent boom outs, you
may need to upsize your VOLUME SPACER.
• Decrease pressure (up to -15psi) if you are
never using full travel. If reducing air pressure
does not allow you to access full travel you may
need to downsize your VOLUME SPACER.
Rebound Knob
• Adjusts return speed “rebound” of suspension
• Turn clockwise to slow the rebound,
counterclockwise to speed up.
• Adjustment sengs are referenced from “full
slow”. To adjust, turn the red rebound knob
clockwise unl it stops, then slowly unwind the
knob while counng each me it clicks.
• Spot recommended rebound sengs– based on
air spring pressure:
• Increase rebound speed if the bike feels rough
and low on fast secons with successive bumps
• Decrease rebound speed if the bike feels
“bucky”, like riding a pogo sck on successive
bumps.

Volume Spacers
• Air volume spacers are installed in the
shock to control how the spring forces
increase as the shock is compressed
• A larger volume spacer will make the
shock more progressive and harder to
boom out on big hits and landings
• A smaller volume spacer will make the
shock more linear and easier to access full
travel.
• Changing volume spacers is a simple
process. Instrucons for swapping spacers
can be found here:
Fox Shock Volume Spacers
Travel Indicator O-Ring
• The shock will push the o-ring down the damper body as it
compresses
• Measure from the shock can to the o-ring to determine your
max travel usage.
• The Mayhem 130 will show 56-57.5mm at max travel
• NOTE: Using max travel on the Mayhem 130 will not push the
o-ring to end end of the damper body. Boom out occurs with
some 8-9mm (.32-.35in) le below the o-ring

Low Speed Compression Damping Adjuster
• Increases rmness and support on slow
compression (downward) stroke of the
fork. Firmer sengs will increase support
for bermed turns and “g-out” style slow
compressions.
• Approximately 16 clicks of adjustment
• Turn black dial clockwise to increase
rmness
• Soer: best for lighter riders, less
aggressive riding
• Firmer: best for heavier riders, more
aggressive riding
Air spring pressure
• Use included shock pump to increase/
decrease air pressure
• Sets sag / “ride height”
• Spot recommends starng by seng the fork
air spring pressure to 37% of your riding
weight (with helmet, pack, gear, etc.) in
pounds. For example, if you weigh 180lbs
ready to ride, you would inate your fork to
0.37 X 180 = 67psi.
• Increase pressure (up to +15psi) if you are
booming out frequently. If adding air
pressure does not prevent frequent boom
outs, you may need to upsize your VOLUME
SPACER.
• Decrease pressure (up to –10psi) if you are
never using full travel. If reducing air
pressure does not allow you to access full
travel you may need to downsize your
VOLUME SPACER.
Rebound Damping Adjusters- Under Black Cap
• Adjusts return speed “rebound” of suspension
• Turn clockwise to slow the rebound, counter-
clockwise to speed up.
• Adjustment sengs are referenced from “full

Mayhem 130/150 Geometry Adjuster Operaon
Your Mayhem frame can quickly and easily be switched between a High Mode and a Low Mode to ne tune
its handling behavior. The High Mode will provide quicker steering response and beer pedal clearance,
which can be benecial at lower speeds and when pedaling along rougher terrain. The Low Mode delivers
more relaxed steering and a lower center of gravity, which will make the bike more stable at higher speeds
and in faster corners. Follow the instrucons below to switch between the modes. The selected mode is
indicated on the top of the shock yoke adjacent to the adjuster cap.
Switching from High Mode to Low Mode will slacken the head tube and seat tube angles by ~0.5°
and lower the boom bracket by 7mm (1/4in).
1. Using a 10mm 12-point wrench, unscrew the rear shock nut two full turns (720°). Hold a
nger underneath the shock yoke at the pin to ensure that unscrewing the nut causes the
adjuster cap to rise, instead of pushing the pin down out of the yoke.

9
2. Use the open end of the wrench to turn the adjuster cap 180°. Either direcon will work.

10
3. Once turned to the desired seng, ghten the nut using the closed 12-point end of the 10mm
wrench. Torque to approximately 12N-m (106in-lb).

11
4. IMPORTANT: Before connuing to ride, verify that the oval head of the shock pin is fully
seated into the oval pocket on boom of the shock yoke:

Leaf Spring Related Precauons
The Living Link leaf spring, and its associated hardware, which include the 8 T30 Torx
fasteners, main pivot clevis, and cap hardware are to be treated as integral to the rear
triangle of the frame.
Do not aempt to remove or modify the leaf spring!
Doing so is likely to damage the leaf spring, hardware, and possibly the rear triangle itself.
Any quesons or concerns regarding the leaf spring should be directed to Spot:
www.spotbikes.com
[e-mail]
303-278-3955
It is recommended to periodically check the torque on the 8 leaf spring mounng fasteners.
This should be done approximately every 100 hours of ride me, or once per year,
depending on which occurs sooner.
1. Fit your torque wrench with a T30 Torx bit and the shortest extension required to reach
the fasteners.
2. Clamp the bicycle securely in a work stand and remove the rear wheel.
3. Remove the forward shock pivot screw and pin, and swing the shock down and
outwards. Very carefully compress the rear suspension by liing the rear triangle at the
rear dropout area. The leaf spring will inially resist compression, but once past mid
travel, it will tend to pull the rear swingarm upward. Let the suspension come to rest in
the upward posion to gain access to the leaf spring mounng screws. Do not over-
compress the suspension causing a back-bend in the leaf spring. This could damage the
leaf spring and lead to failure.
4. Turning the torque wrench clockwise (as seen looking at the head of the fastener) and
verify that all 8 fasteners are at or above 12N-m (106in-lb).

16
1. Make sure your seatpost collar is installed on the frame. The seatpost cable housing is easiest
to install by feeding from the head tube to the seat tube, but can be fed starng at the seat
tube if necessary. Tape the seatpost cable housing to the guide tube at the head tube end.
Make sure to clean the end of the cable housing and the guide tube with alcohol before
taping. Tape the two together in line, and wrap the tape several mes around the juncon for
sucient contact.
2. While feeding the seatpost cable housing into the frame, gently pull the guide tube out of the
seat tube. If excessive resistance is met, the tape joint may be too bulky and should be
reduced. The cable housing must curve around a relavely small radius between the seat tube
and the down tube.
Internal Dropper Seatpost Roung
IMPORTANT:
Your Mayhem frame is supplied with a guide tube installed in place of the dropper seatpost
cable to ease installaon. Please do not remove the guide tube unl the dropper seatpost cable
is installed.

17
3. Connue to feed the seatpost cable housing while gently pulling the guide tube from the seat
tube. When the seatpost cable housing emerges from the port, remove the tape and store the
guide tube in a safe place.
4. Proceed to install your dropper seatpost per the seatpost manufacturer’s instrucons. You
may wish to install other components on the frame before compleng the dropper post
installaon.

18
Rear Brake Hose Roung
1. Begin by installing the rear brake caliper bracket, caliper and any applicable adapter if using a rotor
larger than 160mm. Please note the Mayhem frame is not compable with rotors larger than
180mm in the rear. The brake caliper bracket slides into the axle bore and is secured by installing
the forward caliper mounng screw.
2. Route the rear brake line starng from the caliper, aaching it to the rear triangle using the
supplied zip es on the cable saddles.

19
3. Leaving a small amount of slack between the front and rear triangle, connue to route the line up
the down tube along the groove using the supplied p-clip and zip es.
4. Make any changes to brake line length according to the brake manufacturer’s instrucons.

20
Rear Derailleur Cable Roung
2. The housing will emerge from the corresponding port atop the down tube above the boom
bracket area:
1. Begin by feeding the rear derailleur cable housing into the port at the head tube as shown:
