The Good: These brakes are dependable, did not experience brake fade, and have never bled my 2009s I had on the trek session 88. I also have them on my 2010 intense 951 and these brakes are more dependable than the saint brakes i have on my 2010 slopestyle. I have recently purchased a set to replace the saints on the slopestyle.
The Bad: Nothing. these brakes are simply amazing and are very dependable. I rode them at Snowshoe bike park WV and Diablo. Highly recommend.
Overall: Five stars, especially if you are not into bleeding brakes and look to ride a set that requires minimal if any maintenance.
