Should I go 48x18 (70.3) or 48x19 (66.6) with my Leader build? I feel a little over-geared, for my fitness level, on my Clockwork which is 46x17 (71.4). I'm afraid 70.3 would feel almost the same, while 66.6 would be too extreme a change. FWIW I start bouncing at cadence of about 110+.

Also, I miss the general questions thread.
