This brake is stupendous and is really a bang for your buck. If your looking for a good DH/FR brake that's not too heavy and provides good stopping power, this is for you. It's quite easy too bleed so it is good beginners too.

I like these brakes. They were used for 3 months twice a week at a downhill park. Pads held up well. You should buy brake fluid with it; expect to have to top off the reservoir. Once truly bled (which is very easy on this brake, for any mechanic level), they held perfect the entire time. Very little fade. My only gripe is that the reservoirs protrude a bit much. I killed mine in a crash in under a month by shearing off both reservoir filling bolts. I replaced them with Saints and have no difference in braking power.

I've been running these brakes for a few weeks now and they are superb. They came with a lousy factory bleed, but bleeding them myself was incredibly simple. Once the Zees had a proper bleed the power in them is ridiculous. Lever feel is fantastic with tons of modulation, but they'll lock up just fine if you ask them to. Overall, I'm very glad I spent the extra money to switch from Avid. I have no complaints about these brakes whatsoever. They seem just as good as my friend's Saint setup.
