I am building my first DH bike and my fork just arrived. Its been a while since I owned a dual crown fork (about 10 years) and back then I didnt think about axle to crown heights or geometry in general. I just received my new 2010 Boxxer Team and looking at the Tech Manual, I should have 156mm between the top of the lower crown and the top of the stanchion. I have this from the factory but this only appears to leave 7.5" of travel. so the question, is the other .5" being sucked up by the top out spring or should I move the lower crown to compensate? TIA.
