chain Rings
The Tranny29 can be setup 1X, 2X, 3X
(remember that?) or as a Single Speed.
A direct mount front derailleur mount is
provided for multiple ring setups.
Single Speed Set-up
The Tranny29 features an adjustable
length chainstay with a seatstay
attachment that splits apart, allowing
you to feed a belt into the rear triangle.
We offer the Gates Carbon drive on our
Tranny Unchained version.
The Gates belt needs no maintenance,
and is incredibly silent in its operation.
Adjusting the tension of 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
Mojo hd3
The HD3 framesets ship with a removable
direct mount front derailleur mount and a
cover which mounts on the back of the seat
tube 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 the
HD3. The HD3 is 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:

saddle), and have your helper tighten the
slot machine bolt to 25 N-m. Next tighten
the seat stay bolts to 10 N-m. 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.
Troubleshooting
If the slot machine slips or creaks on hard
acceleration or high torque application,
you can raise the slot machine torque to
30 N-m.
Your Tranny29 comes with an application
of Carbon Assembly past 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.
