Re:
I was using the smallest ring on my cassette and that was 13 and middle ring was 34 I think. so yes it gives the same ratio of what you said.
i've read the single speed thread on here and gear ratio is the main talking point. i've never had a single speed before but my pub bike gears packed up yonks ago so I was stuck in 1 gear for a few years. so I suppose I have been ss for a while, but the gear I was stuck in was Ok for just tootling about on so it doesn't really help me.
i've got the bike to how I want it, just need some replacement cantilever brakes, work out what saddle I want and obviously what rings to get then all sorted.
