Overview “AC-2” = Dual Angular Contact. This describes the use of both angular contact bearings & angled bearing cups/hub bores used in the hub design. The AC-2 hub features revolutionary bearing installation & function never seen before in a bicycle hub. It has been designed from the ground up for ease of maintenance & optimal bearing performance. The AC-2 Cassette Hub also offers changeable pawl/spring configurations for varying points of driver engagement to suit a rider’s personal preference. Here are a few key points of the AC-2 BMX Cassette Hub: -The AC-2 hubs use 20mm Angular Contact bearings with a wave spring pre-load. Bearings are pressed into tapered cups that mate with the angled bores machined into the hub shell. This design feature allows bearing/cup to be easily installed & removed from hub shell without any special tools. No more presses or hammers needed! Another attribute of the tapered bearing cup/angled hub shell bore design is how the bearings seat in the hub. The bearings/cups on each side of the hub shell are in perfect alignment with each other! This ensures superior bearing performance & less chance of premature wear. -Hub shell & driver literally “float” on the axle. The only force on the bearings is supplied by the wave spring (which delivers the appropriate bearing pre-load needed for angular contact bearings). Tightening of axle bolts has absolutely no affect on the bearings! -The bearings, wave spring, & shim (s) are secured on the axle by one retaining ring. The only tool used to assemble/disassemble the AC-2 hub is a pair of snap ring pliers! -The AC-2 hub cassette driver is also unique. It allows for changeable P.O.E. (points of engagement). The hub driver comes standard with 6 pawls & springs. This option offers 96 P.O.E. -Maximum engagement. The other choice is to use just 3 pawls & springs. P.O.E. is reduced to 48 & minimal drag is achieved. This is a rider preference choice & both have a unique sound! -The proprietary Profile Racing 10 spline aluminum cassette body means that you can use Profile's standard steel, Elite, or aluminum cogs ranging from 12t to 18t. section Product Specs HUB TYPE: Cassette AXLE: Female Bolts DRIVER: Choose In Basket SPOKE HOLES: 36h WEIGHT: 370g / 13.05oz ...
