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.
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
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
+ spacers + 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.
