I’ve found a gear ratio that allows me to remove the chain tensioner that I was using. Originally I was running 32/16 with a half link. I tried 32/18 but still needed the tensioner. It was so close that I was sure 32/17 would be the right gear. However, Gusset do not manufacture a rear 17t sprocket so the only one I could find was made by surly but retailed at £20, a little pricey when I wasn’t really sure. This did make me think that an odd numbered rear sprocket would be the answer and got hold of a Shimano DMX 15t rear sprocket for £4. I had to take the half link out to get it to work but the difference is incredible, the bike is so much quieter and there is no longer that dragging feeling whilst pedaling. If you’ve got vertical dropouts and are running a chain tensioner I highly recommend experimenting to try and run without one, you will not regret it.
