The Pro 4 Rear hubs use a new 44 tooth ratchet mechanism. The flange diameter is increased, adding important stiffness to wheel builds. The machined hub shells are. The 17mm axle runs on five cartridge bearings. Pro 4 hubs are 6 bolt disc compatible and available with 28,32 holes. Choose from six anodized colours. Rear hubs with Shimano compatible freehubs features a larger bearing, will be supplied ready to take 11sp cassettes.
With many DH riders using short 7 speed cassettes, we saw a potentially missed opportunity to improve the strength of rear wheels. Our new DH rear hub moves the drive-side spoke flange out to the shortened cassettes, allowing a far wider flange spacing over a standard hub, leading to a stiffer wheel.
