Hey. Got them, swapped them out with the Hopes I had on and so far loving the difference. On a really familiar bit of downhill track I was able to brake a bit later than previously with no issues.
The lever action is so much smoother, it takes no effort at all and one finger braking is fine, even though the lever is a a bit bigger.
Out of the box I just fit them with some tape to get the sizing right, then bled them whilst off the bike.
The bleeding process is a little longer than with other brakes if you do the whole thing, but it gave me a good result first time. I just followed the online vid from Hayes. I’m running them with Hope rotors and they fit, no rubbing.
