installation instruCtions

The correct installation of your new Bontrager fork is critical to your 

safety, so this work should be performed only by an experienced 

mechanic. The installation portion of these instructions is written for 

an experienced mechanic. If you are not sure of your ability to correctly 

install this fork, have the fork installed by your Bontrager dealer.

Make sure your fork is compatible

Changing the forks on your bicycle could alter the steering of the 

bicycle. Before installing this fork on any bike, check with your dealer 

or the Bontrager technical service department to ensure that these 

Bontrager forks are compatible with your bicycle frame.

Bontrager forks are not compatible with any mechanism which 

clamps around the fork blade, with the exception of bicycle computer 

sensors. Except for forks with eyelets for fenders or a rack, do not 

use mechanical fasteners to attach any other parts to this fork. If you 

are unsure of what items can be attached to this fork, consult your 

Bontrager dealer.

This fork has the following dimensions, which cannot be modified:

• 100mm front axle O.L.D. (Over Locknut Dimension)
• 28.6mm steerer outer diameter
• 30.0mm fork crown seat diameter

basic installation information

Follow standard installation procedures for threadless headsets, and 

aluminum or steel steerers. Avoid scratching the fork. Inspect all parts 

for burrs or roughness and remove them before installing. Also read 

the section 

Safety Requirements

 on page 4.

When cutting the steerer, remember the saying, “Measure twice, 

cut once.” Any change in the existing overall 

stack height (head tube + headset stack height 

+ s stem steerer clamp height) will 

require a different steerer length. If no change 

is made to the overall stack height, you must 

still check that the existing steerer is of the 

correct length before determining the correct 

length for the new steerer (Figure 3). If in 

doubt, it is much better to leave the steerer 

long, and cut it shorter at a later time.
