Effects of changing the axle to crown length

Just wondering if there was a formula for working out the change in HA if I mess with the a2c of the forks? Current HA is 66.5 with a 545mm fork. Was just wondering what + or - an inch or so would make?

About a degree.

With a fully there is often no change.

Ah right, had done a bit of reading on other sites and they made it seem like the slightest change (fs or ht) could ruin a frames handling!

Cheers nick (again!)

a small change can make the bike feel very different.

i couldnt get on a bike and say "hmm, this feels like a 70 deg HA" or "this feels like a 69 deg HA" but i notice quite easily when my head angle has changed, i would say a degree is a massive amount in my experience.

It can. 1degree can be felt.
