good braking for good price

4 piston fun that won't break you when you have to replace. if your not a weight weenie this will stop you quick and the modulation for shimano is there without crushing your brake lever to the handlebars.

Faster more confident/controlled braking

Best upgrade I’ve done to my bike, shipping was lighting fast as well!

Excellent Bang for the Buck

Hard to beat for the price. I paired this brake set with the Shimano XT SM-RT86 Ice Tech Rotors for my bike park rig. After a season of shuttling trails and long days at the bike parks, these brakes still work great. These brakes give me the confidence to ride faster because I know they will stop when i need them to stop.

It's only towards the very end of day at the bike park on a hot summer day, after hours of laps and descents, that there is a slight bit of brake fade. It hasn't been anything to worry too much about because the day is pretty much over, and the brakes will be just fine the next day when I would come back to the bike park.

Great durability, lots of power, and just an overall great set of brakes.
