Since the original question seems to have been answered, I have a new one that would fall under the scope of this thread. I bought a 36T sprocket to go on a beach cruiser type bike with coaster brakes. I just put the sprocket on last night and realized that it is very very close to the spokes. I put the chain on to see how much room I would have and its on the scale of millimeters. So my question is this, what do you reccommend I do to remedy this problem? I cant put the other rubber spacer on the outside and "sandwich" the spokes because the way the coaster brake and axel are designed because then my sprocket wouldn't be on the dust cover for my coaster break. I was thinking about getting a large washer, if I can find one, or possible getting some metal and making my own. Suggestions?
