OK, really naive question...
But what dictates the travel that you should select for your front forks?
80-140 seems to be the range for regular XC with the larger stuff for the DH class. I can appreciate that, as you want more travel to absorb the impacts of a fast DH ride.
But for XC, why would you choose say 100 over 120 (or vice versa)? Is it to do with weight, recoil speed, cost, bike geo?
Until now the forks I've used are the ones that have been supplied when the bike was bought - or I've replaced like with like on the basis that the manufacturers must have a pretty good idea of what goes well with what for the target market.
I expect terrain is as important as anything. Looking for something to be used in the Peaks for XC work, would 120 be quite adequate?
