tranny29 gearIng
The Tranny29 can be set-up 1X, 2X, 3X
(remember that?) or as a single speed.
A direct mount front derailleur mount is
provided for multiple ring set-up.

The Tranny29 features an adjustable
length chainstay that serves as a chain
tension adjustment when running in
single speed mode. It also features a
seatstay attachment that splits apart,
allowing you to feed a Gates Carbon
Drive belt into the rear triangle.
The Gates belt needs no maintenance,
and is incredibly silent in its operation.
Adjusting the tension of the belt is easy,
particularly if you have a helper. Here is
one way we’ve found works well:
Once you have the Tranny29 completely
assembled and the belt is in place,
loosen both the ‘slot machine’ bolt
behind the bottom bracket (accessible
from the non drive side) and the seat
stay attachment bolt. Using a helper,
sit on the saddle with all of your weight
and bounce up and down a few times.
Settle onto the saddle (feet dangling is
best so 100% of your weight is on the
saddle), and have your helper tighten
Mojo Hd3 / Mojo 3 cHaIn guIde
The Mojo HD3 and Mojo 3 framesets ship with a
removable direct mount front derailleur mount and
a cover which mounts on the back of the seattube if
you’re not running a front derailleur.
We manufacture a removable ISCG 05 mount
which mounts on the splines on the drive side of
the bottom bracket. Standard procedures apply to
mounting an ISCG 05 compatible chainguide or bash
on both bikes. They are also compatible with all
common direct mount front derailleurs in both 2X
and 3X configurations.
If you need an ISCG 05 adapter, a derailleur cover or a
derailleur mount, they’re available in our online store:

To determine the correct chain length: shift into the
large chainring and largest cog and let all the air out
of your shock (on suspension bikes only, duh).
Thread the chain through the gears and derailleurs,
compress the suspension all the way to bottom out,
and cut the chain at the minimum length needed with
the rear derailleur stretched out.
the slot machine bolt to 25 Nm. Next
tighten the seat stay bolts to 10 Nm. If
you don’t have a helper, stand on the right
side of your bike and lean over your bike
with your stomach on your saddle. Put as
much weight as you can on your saddle
while tightening the slot machine bolt.
Note that Gates publishes a much higher
torque setting than what you will achieve
with our method. We have found that
the added stiffness of the Tranny29 rear
triangle allows you to get away with
lower belt tension.

If the slot machine slips or creaks on hard
acceleration or high torque application,
you can raise the slot machine torque to
30 Nm.
your Tranny29 comes with an application
of Carbon Assembly paste applied to the
internal faces of the slot machine. If you
are having trouble with the slot machine
holding, a re-application of the assembly
paste should be tried.
Be sure there is Ti anti-seize on the slot
machine nut on the drive side. It is applied
during assembly of your Tranny29 so you
shouldn’t need to.
