XTR Caliper

The R-Spec rotor is a proprietary casting done to Baer’s specifications from a foundry in Europe known for casting some of the highest quality cast iron race rotors. This project was in development for almost 2 years with the end goal of building a purpose built, race rotor that was lighter than our current offerings (3 lb savings per rotor) yet offered a substantial improvement in rotor life. The R-Spec rotors come in a slot only finish and are available as an upgrade to any of our 14” Extreme+ systems and feature a unique hat (this is a floating rotor).
The XTR is Baer’s flagship offering, featuring a forged mono-block caliper that is mounted to a 14” or 15” 2-piece rotor. It employs current state of the art race technology usually only found in very expensive race calipers, and Baer brings the same technology to the road going/
street market.

Available as individual calipers, or as an upgrade to any Extreme+ brake system

Machined out of one solid piece of 2618 aluminum for the ultimate in rigidity and weight reduction.
