well min efeels stiff as hell, i have a magura with 2 bolt echo booster and it is brilliant. just make sure you get a decent booster for it in the begining and it will be fine. best frame i have been on and i have been on a few, control, pure 06, zenith, adamant a1, pitbull 05 & 06 etc... so i would say good buy to anyone who gets one.
