heh.. that's about what I was hoping for on my top end! Well I've got a freewheel I was experimenting with unpinning the cogs on.. I may just have to try a big cog first and step down slowly till I find what I like then.. hmm I'd need a 22t or 24t to get down to that range though..and according to sheldon at 64 GI would be 17.1 mph at 90rpm's, isn't that a bit slow? I'd really like to know...
