a Cross Country Rider Date Reviewed: April 22, 2013 Strengths: These brakes look really great. They came stock on my S-Works Epic so they go with the entire XX package that came on the bike. Weaknesses: Adjustments galore, but painful to get them dialed in. I wont remove my front wheel from the fork ever once I get the front to ride rub free or it take me 15-20 minutes to get it back aligned. The pistons appear to stick and are not rugged.

a Racer Date Reviewed: September 2, 2012 Strengths: You can't mount your dropper shifter and brake on one clamp. Weaknesses: Pistons stick need to bleed monthly or more. Replaced original under warranty. LBS couldn't bleed them. Second set same problem. Constant bleeding. Really fun when 15 miles out with no rear brake and have 20 miles to go. Front and rear piston occasionally stick. Bottom Line: Expand full review >>Similar Products Used: magura, shimano, formula

a Cross Country Rider Date Reviewed: June 26, 2012 Strengths: Good stopping power (when the lever doesn't go to the bar) and light. Weaknesses: Had them for about a year in which time they were bled 12 times. I found that 20 hours or riding was all that it takes to get air in the system and you then need to have to bleed them again. Bottom Line:

from Australia Date Reviewed: March 18, 2012 Strengths: Lightweight, good control, Matchmaker (in theory), look great Weaknesses: Matchmaker. This system is great in theory. I've used the brakes for a year now and have had 4 levers break at the mounting point when I've come off the bike. The clamps were definitely loose enough to allow play on a hit but tight enough to allow me to use the brakes with confidence. Out of warranty, these things are far too expensive to be replacing that often. It has put me right off the XX line.

from Hammond, LA USA Date Reviewed: January 31, 2012 Strengths: I have the 2012 Avid XX that no longer uses the CPS mounts. No squealing or turkey gobble to speak of! I lost an arm in a car accident many years ago and only ride with a rear brake setup, so I cannot speak for anything concerning front braking characteristics. The brakes have a ton of power and do exactly what they need to do; solid 1-finger braking. I bled them once when I got them after I cut the line to proper length; great feel and have not had to to touch them since. The Ti hardware is nice and light and it came with the Matchmaker X mounts. So nice not to have to bother with those CPS washers any more!! Weaknesses: Pricey! I got a GREAT deal on a new rear XX setup from a seller here in the classified section.

I think any product that cost this much and does not work should get a total product recall. I will never use an Avid product again. But hate set aside they are great if you do not go down any hills. set as Weaknesses: On any steep downhill they are junk. Judder is the word used above and it is a word that is fitting.
