So I crashed my awesome columbus tubing trek 900 series frame into a car, which pretzeled the fork and put the frame out of alignment. The fork is not salvageable, but I bent the rear triangle back into alignment. I purchased a replacement fork online, but the axle to crown length is much shorter, about 15mm or so shorter. I was thinking that I could get a little of that back with a taller lower stack height.

So which headset has the fattest lower stack? Thanks.
