Trek Speed Concept 2014 Operating and installation instructions
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: Instrucons for the Shimano electronic Di2 shi 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.

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. Before installing any carbon fiber part, or
attaching any component to an existing carbon fiber part, follow these procedures to make
sure the parts or components are carbon-compatible.
As carbon frames have gotten lighter and lighter, you can now feel movement in the tubes
when you squeeze them. This is normal and no reflection of the strength of the frame.
However, repeated compression of the sides of the tubes is not good for them, and could
eventually lead to frame damage. Do not squeeze the frame tubing with your fingers, and
especially never clamp the tubing in any mechanical device, including car racks.
Prepare Carbon Parts Before Installaon
Carbon parts can be assembled either clean or with carbon prep:
• To clean a carbon part, scrub both the part and its mating surface with rubbing alcohol
and a shop rag; clean until the rag shows no discoloration.
• Alternately, we recommend applying one of the following special carbon prep products:
• Fiber Grip™ carbon fiber assembly gel from Finish Line
• Park Tool SAC-2 Supergrip Assembly Compound
• Tacx carbon assembly compound
Note: Do not apply carbon prep between the stem and a carbon fork steerer. Gravity, heat, and
vibration work together to allow the carbon prep to move down the steerer into the headset
spacers. Carbon prep is somewhat abrasive and due to the slight motion involved with
the headset spacers, carbon prep can wear away steerer material, causing the fork to lose
strength.
With most carbon parts you should avoid grease. If grease is applied to a carbon part that
is clamped, the part may slip in the clamp, even at the recommended torque specification.
On the other hand, the bearing seats of the Speed Concept frameset do require grease, as
explained in these instructions.
Never Modify The Fork, Frame, Or Components
The parts of the Speed Concept frameset have been carefully designed to meet the strength
and function requirements of safe riding. Modifying these parts in any way could make the
bike unsafe. As an example, removing the redundant wheel retention tabs on fork tips could
make the fork less functional.
Not all parts and accessories are compatible or safe, so only add a part or accessory that
has the approval of the manufacturer. As examples, clamping any accessory on a carbon
fiber part can weaken or damage the part, and using incorrect brake pads on a carbon rim
can cause the rim to overheat and possibly delaminate. Any modification of a frame, fork, or
components means that the bike no longer meets our specifications and will therefore void
the bike’s warranty.

2. Speed Concept General Informaon
The Speed Concept design incorporates a number of special parts with special features.
This section gives a brief explanation of some of the features, their use and maintenance,
and general information about the bike.
Changes From The Previous Version
The 2014 Speed Concept looks similar to the previous version, but there are many changes.
These changes make ‘upgrading’ to the new design impossible. For example, due to a
larger-diameter steering axle and a 20 mm shorter head tube on every frame size, the new
fork is not compatible with the old frame. However, the benefits to the new design make the
changes entirely worthwhile. Here are some of the changes:
• Two-bolt, rear-access seatpost clamp
• Seatpost with two-bolt saddle clamp
• Larger-diameter aluminum alloy steering axle with integrated bearing preload feature
• Steering bumper to reduce possible damage under full fork rotation
• ‘Mono’ aero extension, with bottle mount on top of stem
• New housing routing from bar to frame, with new cover
• Carbon fiber dropouts on 9 Series
• Carbon fiber front derailleur hanger
• Mega seat-box option
Special Features And Assembly Informaon
The Speed Concept frame and parts incorporate state-of-the-art technology and design.
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.
• Carbon fiber construction- Carbon fiber composite is by weight the lightest, strongest
frame material available today. Please read about special care needed for carbon fiber
in your Trek bicycle owner’s manual.
• Integrated fork design- The leading fork design provides the least wind drag of any
bicycle we have ever designed. With the carefully integrated head tube / fork interface,
hidden head bearings, and hidden brakes, the air flows smoothly across the frame.
However, this design limits the rotation of the fork; if you turn the aerobar too far the
fork will contact the frame, possibly damaging the paint. For 2014 we have added an
integrated fork bumper to reduce damage. However, care still needs to be taken.
• Internal cable routing- To minimize wind drag, the cables and housing of the Speed
Concept are hidden to the maximum extent possible.
• Seatpost for either time trial or triathlon- The seatpost can be rotated 180 degrees to
gain different positions. In addition, there are two lengths of seatposts and two offsets
available.
3 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 Informaon
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:

4. Seatpost
This section explain how to install the seatpost, adjust the seatpost height, and how to tilt
the saddle.
The 2014 Speed Concept seatpost has an aerodynamic shape (Figure 4.1), but it can be
turned or reversed in the frame to allow for a wide variety of seating positions. It is also
available in two offsets and two lengths.

To Install The Seatpost
1. Grease the threads of the seatpost clamp bolts (Figure 4.2).
2. Insert the seatpost and tighten the seatpost clamp bolts to 5.2 Nm.
The seatpost can be inserted dry, or for more grip insert it with carbon prep on the
portion of the post that is inside the frame.
To Adjust The Height Of The Saddle
1. Loosen the seatpost clamp bolts (Figure 4.3).
2. Slide the post up or down as necessary.
Make sure the minimum insertion mark is inside the frame.
3. Tighten the bolts to 5.2 Nm.
To Adjust The Angle (Tilt) Of The Saddle
1. Loosen the saddle clamp bolt (Figure 4.3).
2. With your fingers, rotate the tilt wheel.
The tilt wheel acts like a nut instead of a bolt, so it will seem like it is left-hand threaded.
Note: When you tighten the saddle clamp bolt, the saddle angle will change about 3°. To
compensate for this change, turn the tilt wheel one full turn (the direction you turn the
wheel depends on the orientation of the seatpost in the frame) to lower the saddle on the
end at the tilt wheel. When you tighten the bolt, the saddle will flatten out and those 3°
will be erased.
3. Tighten the saddle clamp bolt to 5-7 Nm.
Note: If the tilt is wrong, repeat steps 1 through 3. Do not under- or overtighten the saddle
clamp bolt to achieve the correct tilt.

5. Using A Repair Stand
This section explains how to correctly put the Speed Concept in a work stand.
Do not clamp the frame. The only accepted or recommended method for holding the Speed
Concept is to use the special workstand clamp adapter designed specifically to clamp the
seatpost (Figure 5.1). The adapter clamps only to the seatpost, which must be installed first.
Figure 5.1. Madone clamp adapter
Tools and materials required
• Workstand
• Workstand clamp adapter,
PN 403494
• Adapters, PN 416101
To Aach The Workstand Clamp Adapter
1. Open the clamp adapter (Figure 5.1).
2. Insert the elliptical adapters (Figure 5.2).
3. Wrap the adapter around the seatpost.
If needed, raise the seatpost to provide room for the adapter to clamp.
4. Insert the base of the clamp adapter into the workstand.

To Install The Bearings And Fork
1. Apply a light coat of grease to the bearing contact surfaces of the frame and fork, and
steering axle.
2. With your hands, align the upper bearing and press it into the frame (Figure 6.2).
3. Align the lower bearing with the fork crown (Figure 6.3).
4. Apply a light coat of grease to the external threads of the steering axle and insert it
into the fork: hold the lower bearing and fork against the bottom of the head tube while
you pass the steering axle through the upper bearing, then the lower bearing, and then
thread the steering axle into the fork.
Note: Be careful not to mar the paint; don’t bump the fork against the frame during
insertion.
Figure 6.5. Steering lock bolt passes through lock washer
and into steering axle
5. Tighten the steering axle to 2 Nm (Figure 6.4).
Check that the fork rotates freely without any end play. Adjust with the steering axle
tension as necessary.
6. From under the fork crown, place the lock washer over the steering axle and thread the
steering axle lock bolt into the bottom of the steering axle (Figure 6.5). With an 8 mm
hex wrench, hold the top of the steering axle to prevent spinning while you tighten the
steering axle lock bolt to 6 Nm..
The steering lock bolt centers the steering axle, and when tightened locks the head
bearings adjustment.
