Rear Shock Set-Up
The Mojos uses the following shocks
and shock hardware:
Upper Hardware:
• 21.8mm wide with an 8mm bore
Lower Hardware:
• 40mm wide with an 8mm bore
Mojo HD shock:
8.5” eye to eye 2.5” shaft travel
Mojo SL shock:
7.875” eye to eye 2.0” shaft travel.
If you really want to Harness the
Gnarness of the Mojo HD
If you generally like how the RP23 feels,
but wish for a bit more end stroke resis-
tance, you may want to try an air can
volume reducer kit from Fox. By making
the volume of air the RP23 smaller, the
spring rate will become much more
progressive.
The stock RP23 is quite linear, which is
why aggressive riding can often result in
bottoming. By making the shock more
progressive, you won't give up much
(if any) small bump compliance at the
beginning of the stroke, but you'll get
a much firmer feel towards the end of
the stroke. Contact Fox for an Air Can
Volume Reducer Kit. Want to go bigger
still? We offer the optional DHX RC4.
See ‘tuning the RC4’, below.
If you want to source your own shock,
the Cane Creek Double Barrel Air,
X-Fusion Vector Air, X-Fushion Vector
Coil HLR, the RockShox Monarch Plus
RC3 and the RockShox Vivid Air R2C
are all great options. Note that the stock
tunes of the Fox (that we provide) and
Cane Creek shocks work well.
The X-Fusion benefits from a custom
tuning, and the RockShox units work
best with a low compression, medium
rebound tune (with low comp/low
rebound being the second best Rock-
Shox tune).
Balance That Thing
A balanced bike will ride best. If you
are planning on using an aggressive
fork, such as a Fox unit with the RC2
damper, or a RockShox with an RC2
DH damper, a larger rear shock will
create a well-balanced ride. However,
if you're planning on sticking with the
stock Fox 34 CTD 160 fork, a much
larger rear shock will result in an
unbalanced bike.
Opinions on the aftermarket shocks
differ greatly. That said, a shock where
the progressivity can be adjusted will
usually work best. Air shocks often are
easily adjusted via changing the air can
volume- a smaller volume is more pro-
gressive, and will better resist bottom-
ing. More linear shocks, with a higher
air volume, will bottom more easily.
If using a coil, be sure you have good
late stroke damping control so you can
mimic the progressive nature of an air
shock at the end of the stroke.
Note: the RC4 will not fit on a small
Mojo HD. A great option for a shock
more aggressive than the RP23 is the
RockShox Monarch Plus.
The Monarch Plus is also the only
reservoir shock that will fit on the small
Mojo HD. It'll fit with the reservoir
down and toward the back of the
