Shimano Rotors Deore XT

So far so good! Great stopping power for my enduro bike!

Barry Erlandson
Great rotors, but rather pricy

We did some bike park and my wife wasn't too happy with her new brake performance. She didn't like the modulation of her sintered pads and actually kept overheating them. Switched her to ice-tech rotors and pads and so far things have been much improved. No issues to report other than the pricy nature of ice-tech components.

Big rotors look RAD.

All trail bikes need 203mm rotors, and Shimano XT’s look the business. Who cares about performance look at those 203’s….

Rotors for Pivot Switchblade second wheelset

It was fantastic that Thunder Mountain Bikes had these in stock when there is such little inventory available throughout the U.S.. These are the same stock rotors that perform very well on my current Pivot Switchblade v2 with a Shimano XT/XTR build. These are being used on a second set of wheels. Thunder Mountain Bikes had fast shipping and delivered as expected.
