Very good grips also for mountain bike

Have the grips for some time on my mountain bike, and started gently to test the stability. But even after significantly more intense rides hold bombproof the handles, and just when climbing the croissants are extremely practical.

What, however, has not worked for me is to tighten the screws with 7 nm according to the instructions. Then the handles could twist with virtually no effort. Hand-tightening the screws after feeling but worked well.
