as I'm a newbie to the forum, I hope you can cut me some slack if I break any of the forum rules (I know the guys at lfgss are very uptight about theirs)
I have a surly steamroller in the making which I plan to use as a daily bike, but the occasional bit of cyclocross.
It's pretty much completely built (just waiting for the wheels to arrive) but as I've never ridden cx before, I'm unsure of the technicalities.
On my other bike I ride 50/15 in the notoriously hilly streets of Bristol, which is a ratio I like
I have a 38 tooth chainring up front which I would like to keep, especially as I have a very nice 14t fixed cog which I'll use most of the time.
the question is, what size freewheel should I use? I was thinking 18t might be nice, but I really can't be sure.
Any help is appreciated
