Overview “AC-2” = Dual Angular Contact. This describes the use of both angular contact bearings&and&angled bearing cups/hub bores used in the hub design. The AC-2 hub features revolutionary bearing installation and function never seen before in a bicycle hub. It has been designed from the ground up for ease of maintenance and 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 and 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 and less chance of premature wear. -Hub shell and 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, and 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 and springs. This option offers 96 P.O.E. -Maximum engagement. The other choice is to use just 3 pawls and springs. P.O.E. is reduced to 48 and minimal drag is achieved. This is a rider preference choice and both have a unique sound! -The proprietary Profile Racing 10 spline aluminum cassette body allows you to 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
