my lx's are 170's but I noticed no difference, is it not just the gearing that is messing with you? The trails around pit should not have to many crank ground issues?
Could be, though I did get punted off when the crank ran aground. I'll sort the gearing first I think. I actually have an old LX chainset and the crank arm non drive side is lighter than all the rest. I'll need to whip the rings off it to weigh it
After a fair wee bit of cursing and swearing I've got my Trek to handle rather well thanks to old school 50mm travel forks. The 80mm are too long and made steering slow and ponderous.
Next I may attempt canti brakes if I can get a noodle for the rear cable routing as Vee's dont seem too good on the rear. I'll stick with SS for the mo gearing wise though
