tom if you want we could swap rings, mine is the same but 50. - I wanted to try gearing up a little.
I came back to my parents' house yesterday to find the Sugino 75 cranks & BB and Dura Ace 51t chainring had arrived.
Won't have time or the place to fit them until the week after next though.
The big ring is beautiful, it's going to have to stay, I'll just have to do a little cog shuffle, maybe, or just HTFU.
The chain that is currently on the bike could handle 48x20 with the rear wheel all the way forward in the dropouts, and 48x14 with it nearer the back - will 51x18 and 51x15 fit? Is there a way of working that out?
