Bolt-on Disc Rotor Mounts

FIRST PRINCIPLESWhy buy a whole new hub just to hold a brake rotor? Now you don't have to. Check out the innovative bolt-on Rotor Mounts from a dynamic young Canadian company that can save you both weight and money at the same time.

Here's what the folks at First Principles are saying about their Rotor Mounts:

"We have designed the product to mount quickly and easily to an existing hub using fasteners that pass through the old spoke holes. It's clean, reliable and the performance is indistinguishable from a dedicated disc-ready hub. We have been testing these products on the rugged North Vancouver trails for a year now and they are fantastic."
