Right now since i'm brand new my warm up and race gear is both the same. 49x15 ~ 86gi.
I'm going to pick up a 13 (98gi), 14 (91gi) and 16 (80gi) dura-ace cog soon. I figure i'll use the 49x16 for warm up and 49 x 14 for racing. I can put on 2 cogs on 1 wheel and just flip the wheel around versus having to swap them out every time.
I'm trying to be economic in the purchase and avoid getting a bigger chain ring for the moment.
Warm up before a race is just a 20 lap pace line with everyone else racing that night. I constantly roll in the inner circle field while i'm not racing to keep my legs fresh.
I want to see if a larger gear inch will help my max speed. Right now I figure likely not since i'm not maxing out my cadence with my current setup.
