Well I have bin rideing it as a single speed, I took off the derailers and shifters took off the dork ring and watter bottle holder, put a new chain on it I had laying around. I used the 50 X 21 tooth sprockets . I have bin having a good time with it rideing 5 to 10 miles at a time, and a little snow won't stop it. I nead to find out how to get the sprockets off the rear hub it looks like thay just un screw and I will make a spacer for it, I will allso make a spacer for the frunt chain ring and only use one sprocket. A nice set of rims with 700x 35s would be nice also.
