I wish I would have read the reviews before O ordered from them. They sent me a 3/4" instead of a 5/8 AND it has 13 teeth on it instead of 11 like I ordered :/ . They did ship it in a fast manor, but the wrong part size. I needed by this weekend so I can get my trail bike done and take it with me but now, I'll be lucky to get it done and have it ready. They can't even make things right until they receive their part first. I'm afraid to order another one because they didn't make me feel like they even knew what happened. I would stay away from these guys and take warning from all of these negative reviews. They say they have a CYCLEPLICITY FITMENT GUARENTEE, BUT THEY DONT EVEN SAY WHAT THAT MEANS. Buyers beware. I can't say how they handle returns yet because I haven't done it yet. I tried to send them a pic but they really weren't interested in their error. This photo clearly shows that the part was a 6/8 or 3/4 instead of a 5/8 like the old part on the right. If I can get another part pic up, I'll show the 13 teeth as well. Sad...
