2014 Speed Concept: Service Information
When we introduced the Trek Speed Concept bike in 2011, it was the fastest frameset
we had ever made. The 2014 version is even faster. It has shaped tubes, hidden front and
rear brakes, very thin-walled carbon tubes, and a new front-end design including a new
handlebar configuration.
Special Assembly Techniques Required
Because of the unique features of the Speed Concept, it requires assembly and adjustment
techniques that are different from other bikes that are explained in this manual. We have
also provided general maintenance information:
•
Carbon fiber care
•
Head bearings installation
•
Bottom bracket bearing installation for a variety of bottom bracket types
Please save these instructions for future reference. Also check www.trekbikes.com for
updates.
Some of the tasks in these instructions may have been done by the factory. We include the
instructions for these steps here for later reference when you need to perform service on
this bike.
Note: Instructions for the Shimano electronic Di2 shift system are in a separate document. See your dealer.
These instructions are written for an experienced mechanic. If you need further information,
refer to your bicycle owner's manual, the instructions in a bicycle mechanic's handbook, or
consult your dealer. These instructions are not intended to replace the information in the
Trek Bicycle Owner's Manual. You should also read that manual as it contains important
use, safety, and maintenance information that also pertains to the assembly of this bicycle.
Note About Performing Mechanical Work On Bicycles
Many people think of bicycles as simple machines, almost toys. However, modern bicycles
use high-tech materials and designs that rely on correct maintenance and precision
workmanship. If any part on the bicycle is worn, corroded, rusted, loose, or damaged in
any other way, replace the part. If you do not have the correct tools or experience, do not
perform the tasks in this manual; take your bicycle to your dealer for service.
In some cases we provide several methods of checking the tightness or connection of parts.
The most preferable of these is always the one with the most precision. In other words,
correct mechanical work requires that all bolts be tightened with a torque wrench.
Incorrect mechanical work on your bicycle could lead to damage or premature breakage of a
part, which could cause you to fall and lead to serious injury or death.

  • Page 3: Working With Carbon Fiber Parts

    1. Working with Carbon Fiber Parts Carbon fiber parts are different from metal parts, so they require different treatment. This section explains some of the specifics. Also see the Trek Bicycle Owner’s Manual. Avoid Sharp Edges Or Excessive Pressure Carbon fiber composite can be damaged by sharp edges or clamping mechanisms which cause a point load, or a high pressure area.

  • Page 4: Speed Concept General Information

    This may require special consideration or techniques during assembly, use, or maintenance. • Compatibility of parts- Trek only recommends Bontrager parts for the Speed Concept bike because with these parts the torque specifications and crush strength have been evaluated by our engineering staff. Other parts might not meet our requirements, and could lead to damage.
