Crank length and the moment you hit the ground in a velodrome
I normaly use 165 cranks on a wooden velodrome track.
The banks there have 43° or 47° degress-
Now the most time i am inside on the 47° track.
For me is the question, if i stay straight not one degree inside to the center, how much space is there till i knock the ground.
Not only the crank length are decide about... the BB drop from my frame and the pedal axle is the nex point.
I try to find data in geometry from several frames for track cycling
My own frame has only 45 ° DROP
Cinelli has 50 °
PlanetX Track Pro has 58 °
Caad Track 10 has 57 °
Look is about 50°
So i think if you uses tracks with higher banks 45° plus...
You have to look for the BB drop also ...
For Sprinters not above 50° and crank length 167,5
A 57° frame with 170mm cranks could you knock out from the ground. What you thing about?
