Well, I'm currently on my 3rd new roller that I bought today. Something ain't right. It just gets chewed up, doesn't seem to want to roll. It rolls when you are just putting around, but when I get on the gas it just looks like a dog just chewed it up. The parts guy says the ones he gave me match the part numbers for the bike and he gave me new hardware for them. This is what I got: the bolt, washer, small sleeve, large sleeve and nut. I put them on according to the part diagram and it doesn't work. The roller has a 1/4" hole through it with what looks to be a 7/8" recess on one side. Is this the right one? I saw the ones from UPP, getting them next, but just for temp reason, this one has to work for now.
