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.

Here are a few key points of the AC-2 MTB Disc Brake Front 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 literally “floats” 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 thru axle 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!

*Profile Racing does offer a simple tool to aid in retaining ring installation and bearing/cup removal, but is not necessarily needed.*

-The Profile Racing AC-2 hubs and cassette drivers are manufactured from a high grade, aerospace quality billet aluminum.

-Front and Rear hubs sold separately.

Ceramic Hybrid bearing option available for hub shell bearings.
