As noted by some other reviewers: Initially the attacks appear to be very suitable - grip, (very) good lock, ergonomic. After a few months (!) Dissolves the top layer of otherwise grippy rubber coating and leaves a sticky substrate, after cycling an unpleasant residue on the hand leaves. That is the only point of criticism, however, of the handles can slip into the lowest league. After several months you are forced to replace them. In my opinion, this coating has been chosen on purpose in order to achieve the shortest possible lifetime. Therefore, please DO NOT buy! Would a different coating was chosen, the handles would surely play in the front league. So do not unfortunately.
