Cook Bros. Racing


CBR Q2 20 Millimeter Rear Hub

Regular price $399.99


The Q2 hub – perfection? Pretty much, yeah! Designed to be ultra stiff, and ultra fast, they feature 36-hole drilling, compatibility with 20 mm axles and a cold-forged, one piece hub shell design that embodies that good old Cook Bros. Racing style.The cold-forged chromoly driver body features 6-pawls and 60 points of engagement, giving the hubs near instant engagement. Using this design increases reliability while reducing drag. The spline pattern is compatible with Onyx™ Ultra Cogs.

A range of compatible Cook Bros. Racing axles are sold separately. The 20 mm is compatible with all Race Inc. frames. For those using 10 mm/3/8” or 15 mm dropouts, The Cook Bros. Racing adjustable 10, 15 and 20 mm axles also are available. It’s like a bike buffet!
