If it says "5 inches" Does that mean with the forks compressed? With the springs in or out? If compressed, I'm guessing it means with the springs out, right, since otherwise it would be...impossible to check. Why is fork oil level so important, anyway, as long as there is sufficient oil in for the damping rods to work? I hear that half an inch difference in the level can make a bike difference in handling...in what way? Is it more or less important for damper rods or cartridge forks?
