Details

A lightweight Campagnolo compatible hubset designed expressly for the demands of road racing.

Light
The R45 hubset is 20% lighter than King's Classic hubset at 328g. They designed sleek new hubshell bodies and new 17 mm axles. That's 17 mm from dropout to dropout resisting deflection during cornering or when the power is full on. Chris King designed a driveshell with a twin bearing design that responsibly removed as much weight as they could from the inner components. Even their patented RingDrive engagement system was redeveloped resulting in a quiet, fast-engaging 45-tooth stainless steel system unique to the R45 rear hub. All of this comes with the standard Chris King 5-Year Warranty and is compatible with Campagnolo 9,10 and 11 speed drivetrains.

Lock Rings
The R45 for Campagnolo comes standard with an 11-tooth lock ring which is required for use with the Chris King driveshell. An optional 12-tooth lock ring is also available at your favorite shop or directly from Chris King.

Fast
Chris King designed and built a bearing specifically for the R45 hubset. As with every King bearing, these stainless steel sealed bearings are made in-house in Portland, Oregon and individually hand-checked for precision and smoothness. Chris King's proprietary bearing design allows them to place more rolling elements per bearing meaning greater durability and precision. R45 bearings also feature lightweight, low-friction seals for fast rolling and can be easily serviced at regular intervals using only a single 2.5 mm hex wrench and penknife.

R45 Options:

Ceramic Bearings - Made in-house
Chris King makes their own ceramic bearings and theye build them to the same exacting standards as their classic, time-tested stainless steel ball model. Pairing the corrosion resistance of ceramic balls with Chris King's proven sealing system allows for greater flexibility with greasing options. Chris King builds their ceramic bearing R45 hubs with a very small amount of silicone-based lube for a system with very low drag. Take advantage of Chris King's user-serviceable bearings and change to a dry lube for the ultimate in race-day performance.

Stainless Steel Bearings - Made in-house
The R45 Campagnolo hubset also has the option of stainless steel sealed bearings. As with every King bearing, these bearings are made in-house in Portland, Oregon and individually hand-checked for precision and smoothness.

Hubshell Drillings
R45 front hubs are available in 20, 24, 28 & 32 hole options.
R45 Campagnolo rear hubs are available in 24, 28, & 32 hole options.
