What's the formula for this? My SGS with 8 inches of travel currently has an 8.75x2.75 shock, thinking of swapping to an 8.5x2.5 shock to slacken the HT angle and drop the BB a little. How do I calcualte how much travel I'll lose?
(x/y)t=T
x = new shock stroke
y = original shock stroke
t = original travel
T = new travel
this should get you pretty close...Coma is pretty much on the money
What nerds with their formulas and calculators ( I dont trust nerds ) Just kidding, but seriously only take out your calculators if your own sense of observation cant help. Keep your observation senses sharp
Instead of spending money on a new shock, a lot of people with the SGS's just drilled new mounting holes for the shock, the upper ones that attach at the seat-tube mast plates. There is plenty of material there to work with, and it wont reduce your travel. Figure out the geometry youd want to acheive, unbolt the top shock mount and then slide the shock to a place in which the geometry you want, occurs.
