I am currently doing beginner xc racing on a new 600ht. It has the stock 100mm dart 1 fork on it. I have a brand new dart 2 80mm fork that I'm considering swapping. The total axle to crown difference after factoring in sag will end up being 13mm shorter? Anybody ever try running a shorter fork on one of these frames for xc racing?

Horay, my first post!
