R45 Disc Centerlock Hub Addendum
Centerlock rotor mounting system licensed by Shimano®
Centerlock is a proprietary mounting system that requires a Shimano®
lockring to complete installation of rotor. Chris King R45 Disc Centerlock
hubs are compatible with the following Shimano® lockrings:
Compatible Lockrings
- Front (Y8K198010) – Typically supplied with genuine Shimano rotor. Or
(Y26N98030) – Typically sold as an after market part, also available direct
through Chris King under part number PHB355
- Rear (Y26N98030) – Typically sold as an after market part, also available
direct through Chris King under part number PHB355
Centerlock Rotor Installation:
Front Hubs:
Please follow rotor manufacturer’s installation instructions.
Rear Hubs:
Before installing the rear Centerlock rotor the adjusting clamp must be
removed. Follow steps below for removal, installation and setting hub
preload.
Clamp Removal:
1. Loosen 2.5mm hex bolt on adjusting clamp and then remove R45 QR
Insert from main axle assembly by pulling it directly out of the non-drive-
side of axle. [Note: If the QR Insert is dicult to remove by hand, insert
a long P-Handle or L-shaped 5mm hex wrench into the driveside of the
axle. The QR Insert should remove with a light tap to the exposed hex
wrench from a plastic or rubber mallet.]
2. Unscrew adjusting clamp and remove it from axle. By pulling onto the
adjusting clamp, once free from the threads will also remove steel axle
end caps on thru axle assemblies.
[Note: If the Axle End Cap is dicult to remove using only the adjusting
clamp, use a small at- head screwdriver and insert it into the Axle End
Cap slot, twist the screwdriver and the Axle End Cap should come o
with the screwdriver.]
3. At this point the Centerlock rotor (or Centerlock to 6-bolt adapter) can
be installed. Make sure to follow rotor manufacturer’s instructions. (Use
Shimano Y26N98030/ Chris King#PHB355 Lockring on rear hubs)
Clamp Install:
1. Thread adjusting clamp onto the protruding threads on the non-drive-
side of axle.
2. On QR axles, insert R45 QR insert into non-driveside axle end. On
142mm x 12mm thru axles, ensure steel axle end cap is snapped onto
axle by pressing the axle end cap by hand.
3. Snug adjusting clamp up to bearing.
Rear Hub Adjustment:
The R45D Centerlock rear hub features an adjusting clamp and bearing
spacer spring that maintain proper bearing preload and seating.
1. Secure the hub/wheel into the bike or truing stand with quick release
or frame thru axle system.
2. Push the hubshell toward the driveside. This compresses the bearing
spacer spring in the driveshell and ensures proper bearing seating.
3. While maintaining pressure on the hubshell, tighten the adjusting
clamp onto axle until it stops against bearing. Do not over tighten.
4. Once adjusting clamp is in position, tighten adjusting clamp with a
2.5mm hex key to 10 inch- pounds (1.13 Nm).
5. Double check adjustment by attaching wheel to bicycle frame. Check
for bearing play or binding, and readjust adjusting clamp if needed.
