Hi Rik,
I’m a little biased but sure no problem, I’ve never used BB7’s so can’t compare with those but….
Power – We’re using 140mm rotors as we don’t want throw you over the bars power, think better than a very good canti on an alu rim in dry weather with no fork judder or squeal, but all the time no matter what the weather or how much mud is on the rim.
Modulation- Very good, can feel the pads precisely through the levers so you know how it’s grabbing, it doesn’t snatch just nice and controlable.
Feel – Is heavier than an X2 race set up as there is little mechanical advantage from the lever, the cable just pulls through the piston, having said that it’s no worse than a canti and you don’t have to pull as hard anyway.
Weight- We reckon to be giving away 200g over a light canti setup, no problem for me, I’d take that any day of the week….
Further questions feel free to ask…..
