Hey folks,
Got an old mid-90s Cannondale F400 that I've run as a single speed for quite some time. I've always run an Endlessbikes 32t chain ring and 19t cog. Great for trails in the mountains. However I've wanted to swap to a 16 or 17t for flatland around town. Unfortunately since I have verticle dropouts where there is no room for chain adjustment, the chain always ends up too short or too long to run a 16t or 17t. 19t is the only one I can run paired with a singulator.
So I decided to try a Paul tensioner. Everything setup pretty easy. Installed the tensioner vertical exactly how they recommended. Tensioner is perfectly in line with the rear cog and both are in line with the chainring. There is plenty of chain wrap. With that said, I keep having the chain jump a tooth on the 17t cog.
The Endlessbikes chainring has alternating teeth that go from wide to skinny...matching up to the chain itself. This feature prevents you from using any half links to get the proper distance on the chain. I'm trying to keep the chain ring in play so I figured using the Paul Melvin would eliminate the problem.
Question: Do you think it is skipping due to the rear cog being an odd number (17t) vs. the even number chainring (32t) and tensioner cogs (10t)? I run the 32t x 19t all the time with a singulator with no problems. However when I try the Melvin on the 17t...it keeps slipping. Any ideas, thoughts, input, suggestions would be great! I'm baffled.
