1) Depends on the event. You could run 180 or more for pursuit. I would
not run longer than 170 for general track racing at Alpenrose.

2) The rental bikes have 46T rings and 14 and 15t cogs, i.e. 88.7 and 82.8
gear inches. Generally for guys somewhere between those 2 gears is a good
gear to start track racing.

So I'm building up my very first track bike to hit some Wednesdays and get
going on the track. 2 Questions:

1) Crank length. How long can I go? I run 175s on the road bike, but it
seems most run shorter cranks.

2) What gear ratios are good to start with? Like what are on the rental
bikes?

Thanks,

Chip
