I was wondering if there is some sort of formula that I could use to determine how much a bike's headtube angle would be changed when a forks length is changed. I'm looking at a frame designed around a 120mm fork (69 degree HT angle), but I want to use a 100mm on it, and I'd just like to know how much it would steepen the headtube. Any engineering geeks out there know?
Fork length geometry changes?

its usually about 1 degree i think
Praise jeebus! I was looking for that Dirt Rag article, but couldn't find the issue. Danke!Wumpus said:
Hmmm...so using that math, it would go to 71...right? I can't bitch about that, my current headtube angle is at 73
