Out of all the upgrades I've done to my bike these brakes are the best upgrade. I had high expectations when I popped them on and I still found myself amazed at the preformance I got from them. My first ride with them we got cought in a rain/hail storm and the trail quickly turned into a 3 inch deep stream. Even in those conditions I found them to be just as reliable as they have been on the dry trails since. I feel like I can stop on anything at any speed. Even better was the fact that I didn't have to put a kidney up for sale to get them. Good job Avid!
