Campagnolo-compatible R45 rear hub

The Campagnolo-compatible R45 and R45 Disc rear hub operates in the same way as

the Shimano and Sram compatible R45 hub, with a few differences. The Campagnolo-

compatible R45 hub uses dedicated driveshell, non-disc specific axle, disc specific axle,

spacer spring, outboard bearing, bearing sleeves and cassette lock rings. An 11-tooth

lock ring is included with each hub. A 12-tooth cassette lock ring is available from any

authorized Chris King dealer, or directly from Chris King Precision Components, www.
