Fork offset, trail, shorter? longer?! Undoubtably offset has an impact on your ride. Fox, Rockshox, MRP, and others are all offering up forks in different offset options. While I will not belabor ride quality difference  of fork offset, trail, etc. here, I will touch on the question of, Can it be done / is it worth it on your particular fork:

Fox 36:
