I go cycling always the problem that I abknicke my wrists too far and thus always fall asleep my hands, or fingers. Since it is very unpleasant in the long run, I looked around something and came across these handles. Installation is very easy and fast, 5-10 minutes, depending on how long it takes to do the old rubber grips on the handlebars abzubekommen. Ergon handle is then simply plugged it and tightened with a Allen. The Allen is not included in the other, but thanks to my big IKEA Allen choices in my toolbox was quickly a suitable piece ;-) When installing you should only times sit on the bike and see what is the best position for the hands and then fix the handle easily, then descend and properly tighten the whole. Also you should make a small test drive to see that everything really is fixed. I have after the first long journey which Imbuse (?) Also tightened again. When selecting the ERGON handle you should still make sure that there is not only the handles in different variants, but also in different sizes. Furthermore, you can not use these handles when you have a grip on the handlebars circuit, so if you have to make a ring for switching. For me, the handles have fully paid off, because my fingers no longer asleep. However, it was a bit strange to go at first with these grips for me. This, however, has given quickly.
