A note on this manual
Chris King R45 hubs require care and overhaul procedures that are different from other
Chris King hubs. Be sure to thoroughly read and understand the R45 overhaul procedure
before servicing R45 hubs. We recommend that these hub overhaul procedures be
performed by a professional bicycle mechanic.
General setup
Cassettes
The aluminum driveshells of the rear hubs should only be used in conjunction with
“spidered”-style cassettes. Avoid using individual cogs with aluminum driveshells. We
recommend using our aluminum or Ti cassette lock rings which feature longer threads
to provide a more secure engagement with driveshell threads.
The Campagnolo-compatible driveshell requires the use of a Chris King Campagnolo-
compatible cassette lock ring. Each Campagnolo-compatible R45 rear hub is shipped
with an 11T lock ring. A 12T Campagnolo-compatible cassette lock ring is available for
12-tooth cogs and larger. Contact Customer Service or your local Chris King dealer for
details.
Frame preparation
Check frame and fork dropouts to ensure that they are parallel to each other. Use an
appropriate tool made by a reputable bicycle tool manufacturer. Unparallel dropouts may
damage or compromise the performance of your new hub.
When using any Chris King products in conjunction with other manufacturers’ parts, be
sure to follow other manufacturers’ instructions and recommendations.
Never use thread locking compounds
Thread locking compounds are not an acceptably reliable substitution for loose threads
or press fits. All Chris King components are engineered and manufactured to exacting
tolerances to eliminate the need for thread locking compounds. Please refer to the
bearing preload adjustment procedure (see page 4) to properly adjust hubs.
Dropout spacing and retention devices
R45 front hubs are designed to work with 100mm fork drop out spacing only. Do not
attempt to use your hub with any other dropout spacing. The axle is designed for exclusive
use with a skewer-type retention device. Do not modify or alter the axle to accept thru-
bolt retention devices.
R45 rear hubs are designed to work with 130mm frame drop out spacing only. Do not
attempt to use your hub with any other dropout spacing. The axle is designed for exclusive
use with a skewer-type retention device. Do not modify or alter the axle to accept thru-
bolt retention devices.
Wheel building
Proper wheel building technique is essential in creating a strong wheel. Wheel building is
a skill that requires proper training and specialized tools and should be done by a trained
professional.
