I bought the Chainglider along with a new bike and I'm completely disappointed. Directly when the bike was to hear a rattling and scratching. Since I have not heard in a trial run on a different wheel, I found not so bad. I have at the back of the Chaingklider adjusted and herumprobiert who really loud and annoying noise but can not eliminate a little. It was only when I had the Chainglider once completely dismantled and reassembled, the noise was almost completely gone and I was satisfied. But that has stopped only about 100km and now it's like before. I tried again around see something that has not helped. Maybe this will help re-complete dismantling, but what I consider ALKS impertinence.
In addition, it seems to me that the opening angle of the rear part does not fit the bike geometry, namely is too large, so that has to grind and rattle the chain. The number of teeth fit, I've checked, but the Kombinateion from front and rear tooth number is apparently not compatible.
For the price a really bad product. That's the only reason why the thing has not already been recycled.
