5 foot 3, 165mm cranks on both track and road bikes.

Had 170mm on old clumker, but wouldn't go back to them as the stretch is too long for my legs. Felt like a pygmy when I first got the 165s, but now spin my heart out in 42/12 pacing guys grinding away in 53/11

Have 36 ctc handlebars on both road and track bikes. Much comfier than what bikes usually come with. Haven't worried about any other adjustments than getting the right seat.

Stuff's available if you want it - and if your LBS isn't supplying, let them know you can spend your money elsewhere if they want to make it a hassle for you to get what you want.
