The Profile AC-2 Race Cassette Hub utilises both angular contact and angled bearing cup/hub bores in it's design allowing bearings to be easily installed and removed for the hub shell without having to use all the tools, hammers and presses.

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.

This unique bearing installation and function has never been seen before in a bicycle hub, designed from the ground up for ease of maintenance and optimal bearing performance. The AC-2 also offers changeable pawl/spring configurations for varying points of driver engagement to suit a rider's personal preference, coming standard with 6 pawls and springs giving 96 points of engagement or you can run it with 3 pawls and springs dropping those P.O.E's down to 48 to offer minimal drag. Both have their own unique sound.

The bearings, wave spring, and shims are secured on the axle by one retaining ring, the only tool used to assemble and disassemble the AC-2 hub is a pair of snap ring pliers! Profile's proprietary Racing 10 Spline aluminium cassette body allows you to use Profile's standard steel, elite or aluminium cogs ranging from 12 to 18 tooth.
