bench vice to hold one of the 5mm hex wrenches
2. Hold left hand stationar y and turn right hand counterclock wise 1/4 turn until
assembly is loose.
3. Hold hex wrenches stationary and adjust bearing preload with adjusting cone.
4. Advance adjusting cone until it just contacts bearing, then back off approximately
1/16 turn (this allows for axle compression while under skewer clamp pressure).
5. Once preload is set, tighten axle assembly to 110 inch-pounds.

1. Remove the hub from the fork. Remove the disc brake rotor.
2. Insert a 2.5mm hex wrench into adjusting clamp hex bolt, and loosen.
3. With adjusting clamp facing towards you, hold opposite end of axle stationary,
and rotate clamp in a counter clockwise direction to unscrew it from the thru-
axle. If adjusting clamp is difficult to remove, insert a 2.5mm hex key into “helper
hole” on adjusting clamp adjacent to 2.5mm hex bolt. Use the hex key as a
lever to unscrew adjusting clamp. Note: 15mm SD hubs feature a steel axle
end cap that will pop off of axle end as adjusting clamp is unthreaded from
axle.
4. Remove the axle from the hubshell.
For bearing service information see “Service of the bearings”, pg. 17.

to axle
O-ring
2. Insert the axle into the hubshell from the disc mount side.
3. Thread the adjusting clamp onto the protruding threads of the axle.

5. Proceed to “Adjustment of one piece axle on ISO front hub”, below.
Adjustment of one piece axle on ISO front hub
(see Figure 6)
The one piece axle features an adjusting clamp which minimizes over tightening or over pre-
loading of the bearings. Adjustment may be accomplished while the hub is attached to the fork.
1. Loosen the adjusting clamp hex bolt using a 2.5mm hex wrench.
