Brake Uncertainty

Not long ago I maybe have discovered what caused my accident last may. Back then I rode with an almost new Shimano XTR Race M-9000 brake. I just made one tour with the new brake. The accident happened on a steep downhill section on a wide forest path. I constantly had to break a little. Suddenly I braked a bit harder end everything went south. Until now I thought the slippery chalk gravel caused my wheel to swing off. But after I read a review of the Shimano XTR at MTB-News I figured that maybe the brake itself was the problem. This version of the XTR brake (and also its XT version) can have a changing pressure point. Means that if you press the brake lever once, release it almost(!) completely and press the lever again, the pressure point moves more far away from the handle bar. So the point where the wheel locks happens earlier. I rode with this brake since August when I was allowed to bike again. I didn’t have any real problems. But I was extremely careful because I didn’t very confident on difficult sections after my spill. After I read the review I tried it and I could reproduce it immediately.

When I first bought the XTR I almost chose the Magura MT8 instead. Maybe I’ll have a look at some secondhand MT8s now…
