Reach: L - I = 570 - 167 = 403
Stack = ???

Can the Stack be calculated from the geometry shown (frame is a Time Edge First from ~2007)?

Well, I made some measurements tonight and came up with the following:

Axle to fork crown = 375
BB Drop = 68 (Axle to ground = 341, BB to ground = 273)

With those numbers, the stack and reach calculator above gives me the following:

Stack = 596
Reach = 388

Perhaps my measurements were off (I triple checked them), but the Reach measurement of 388 seems a bit off compared to L - I = 403 from the Time geometry chart.

You input the correct ST and HT angles?
