The Pro2 Evo hubs have gone from strength to strength since they were launched. Now redesigned with 40 tooth ratchet ring with 4 pawl engagement, giving a quicker drive, running on stainless steel bearings through out and fitted with XD 11 speed freehub.
The hubs are CNC machined in Barnoldswick, England from a single forged billet of 2014 T6 aluminium with a 7075 aluminium cassette body and pawl carrier designed for the new Sram XX1/X01 cassette. Four pawls engage into a new 40 tooth steel ratchet ring which is fixed into the hub shell and is sealed with a frictionless, non contact labyrinth seal. The axle runs on five cartridge bearings. All Pro 2 hubs are standard 6 bolt disc compatible.
The hub now runs stainless steel bearings throughout and brings them inline with Mono RS hub. This means longer life, smoother, free running and even more value for money. With the bearing change comes a new axle. The old 15mm axle is now replaced with a 17mm version. This means total compatibility with Maxle and Maxle Lite and X12 12mm bolt through axles.
