Not to be dense, but how steep should the angles be? And should they be the same front and rear?
Also, how high should the BB be. And is it better to talk about BB height or BB drop (front wheel axle centerline)? Oh, and is there a reason why TOC is required? I'm gonna assume 700C (ISO 622) wheels.
And if someone could list chainstay length and fork offset, I'd be obliged. Thanks!
One more thing... how tight are the clearances?
brake drillings are fine (at least in the rear). toe clip overlap isn't necessarily required, but i feel track bikes should have a shorter front end than road bikes, preferably equal to or no more than 1.5cm more than the seat tube. chainstays should be less than 40 cm. 35-40 degress of fork offset (depending on size of frame and head tube angle). no less that 74 degree head and seattube angle (again, that depends on the size of the frame). oh, and clearances should allow for nothing larger than 23mm tires.
my opinions based on what i will get when purchase a custom/BTO frame.
