TREK SERVICE INFORMATION August 2016
•
Hidden brakes-
If you can’t see them, the wind can’t find them. The brakes are sensitive
to rim width, so a brake will require re-adjustment if the wheel is changed, because.
There are pad-width adjustment features built into the brakes.
•
Carbon rims-
By weight, carbon is the strongest material used in bicycle construction.
It also allows greater flexibility in designing shapes, so Bontrager carbon rims are very
aero. Make sure you use brake pads that are compatible with the rim material.
Preparing And Tightening Fasteners
For each threaded fastener that does not use threadlocker, apply a light coat of grease to the
threads and shoulder of the bolt or screw. Then tighten correctly.
The correct torque is noted on or near most of the threaded fasteners on the Speed Concept
bike. The specification on the bike tells you the range of torque. Do not exceed it. However,
do not leave bolts loose. You should try to tighten a bolt to close to the listed value. Either
condition, too loose or too tight, can cause a bolt or clamp to break.
When multiple fasteners attach a part, gradually tighten alternating bolts in small
increments (Figure 2.1); do not completely tighten one and then start the other. If a clamp
uses a band (Figure 2.2), the gap at either end of he band should be the same. As the
bolts become snug, check the alignment of the parts. Then use a torque wrench for final
tightening. When the tightening is completed, all bolts of a given clamp must be tightened
to the same torque.
For More Information
Trek dealers have access to the Trek Customer Service department for information about
the Speed Concept bikes and parts, so they can order any and all parts for the bikes through
standard channels.

3. Sizing The Bike
Before assembling the bike, make sure the frame is the correct size and, as much as
possible, that you have chosen the correct stem and spacer stack. There is information on
our website that explains how to do this. Visit our website:
