Okay, I've just gotten my Jamie Roy with 46x17 fixed gearing. I've got the other side to spare and so far in my riding, I've noticed I've been going slower on flat roads and trying to go any faster only tires out my legs.
Another thing is I do a lot of my group rides on hills in the 7-10% grade range and I'm positive I won't be able to last with a 46x17fg uphill or downhill.
So I'm thinking I'll make it 46x14 SS or something for downhill/flats and 46x22 for hills.
My question is...is that too much of a change in teeth for one chain?
Also, does that make much of a difference?
