i want the greatest versatility possible, so i think i'll go for 400mm fork height
plugging all my numbers into bikecalc (from Brent Hardy, email me for a copy), i get an appreciation for the scientific art of bike design; it's impossible not to compromise somewhere. in particular, the BB shell angles are giving me trouble--the 1st measurement in specs, the angle from DT to ST--they're generally 60°, and i apparently need about 3° less. i don't have my exact measurements plugged in yet, though, so it's still coming along.
playing with lengths and angles to compromise standover, lug angles, DT-TT interference.
