Our Race Rings have been designed for optimal performance. Featuring our patented S.H.I.F.T. technology, we have optimized shifting performance by maximizing the chain to ring surface contact areas. The Race rings have been machine sculpted for maximum weight savings.
CNC machined in our British Columbia, Canada manufacturing facility.
Outer, middle & aluminum inner rings manufactured from 7075-T6, one of the strongest alloys available today.
Outer rings are made from 4mm thick material & middle rings from 5mm thick material for unsurpassed durability.
> These silver anodized rings come with a huge range of teeth and bolt pattern options (and like Race Face's Evolve rings), are armed with a sensible steel granny when bought as a set - although an alloy granny ring is an option. Unlike the Evolve rings, though, they're available seperately. In terms of shifting they have pins, plates and a very complicated pattern of layered computer designed ramps. In the real world, shifting is good, the silver anodising will keep its good looks for longer than the black Evolves and, despite some deliberate and horrible half shifting, these rings stood up well to scratching. Shifting in muddy condiions didn't suffer either. Available in four or five bolt patterns.
