as a general roadie fit, you're supposed to have about 25-30 deg of bend in your legs when at the bottom of the pedal stroke, when your cranks are at noon and 6 o clock. most roadies i know ride their seat waaaaayyyy too high - track messengers are probbaly the worst offenders as seat height often seems an estimate based on aesthetics, not pedaling efficiency at all.


with seat rail position, make your own plumb out of something metal and pointy. your pedal axle should line up horizontally below your knee when at 3 and 9:00. most trackies like to have their knee 1 cm more forward for more power.


as for stem length, i think fit is kind of a weird thing when it comes to track-city riding.

based on general fit guidelines, the whole bar-top hiding the hub thing is a general rule, but is largely dependent on how flexible your lower back is, and as long as your within the "normal" 50cm-59cm frame size. plus, this rule is based on a fit with the majority of riding done on the hoods, which don't exist on track bikes.

I'm a big fan of a way longer stem 4 risers, a tiny bit longer than normal for drop bars , and an ultra short one for bullhorns. i played around with my fit alot, but putting ,my track bike on a magtrainer and seeing what positions i could hold comfortably for 15-20 min efforts. sounds nerdy sure, but i was able to get a realistic feel for what's the good compromise for a good efficient fit and one that's good for trackstanding, back-circles and skidding.

anyway, flame on.
