Chain Guide
138222 Rev 1 (03/20)
The chain guide has an “open” position (see D) that
can be used to remove the chainring without having
to disassemble the guide itself.
Failure to install and maintain the guide
can result in a moving chain from coming
off. Replace the guide if it is worn, missing
or damaged.

The chain guide is an important chain retention
device that must be used in single chainring
applications (no FD mounted).
Install the chain guide assembly onto the FD mount
(4) using the curved washer (1) and the M5 bolt (2)
using a torque wrench. Position the guide shroud
(3) vertically so it covers the chainring teeth, with
clearance between the guide and the chain, as
shown in next figure A and B.
Adjust the guide shroud bolt (4) to align it so that
the chain does not rub against it when on the
smallest or largest gear of the rear cassette. See
next figure C.

The wheel rim and tire models, and
fender shape used will affect the
fender clearance.
Maintain tire clearance with fender.
Please Note:
(1) Check tire clearance with the tire fully inflated. (2) Mounting a tire with a smaller profile, one
smaller than the maximum tire size for the frame, or currently on the wheel may be required to fit
a compatible fender. (3) Any fender must be secured by the support and should not be loose. (4)
Do not modify any parts or the frame in order to install a fender.
