Right... I've got a coust v2 stock, however...i think its a bit porky in its current state, so im thinking about dropping some weight on it. Spec is as follows: Tryall nuc stem Monty ti bars tryall rear rim on echo 6spd hub kmc k710 onza hognesiums maxxis minion dual ply 2.5 rear maxxis highroller 2.35 front single ply full meta front wheel ( hope xc copy hub and viz rim? ) tensile optimum ace headset echo cnc cranks gu half bashring tensile FFW fsa platinum bb 185 bb7 rear 04 magura The highlighted stuff above are things i reckon it'd be worth changing...whats your views/opinions on this? any more suggestions? I'm contemplating : * Lacing an echo 06 rim-- to a ck hub that ive got spare...or maybe selling this to pay for lighter parts? * Changing the front tyre to a conti or larsen tt? * Maybe changing the rear tyre, although ive tried , on other people#s bikes, the rubber queen, rain king and big betty...and the only one i get on with is the rain king, and that's hardly much of a weight saving considering the price? * changing the front wheel if it really is that heavy? Not too into changing the cranks, as there's not much weight saving....tryall's seem to be fairly rare in 170 isis second hand fro a reasonable price, and ive heard of too many tensile uci's snapping. As I've never used an echo 06 rim, anybody got any opinions on them? they certainly seem to be damn light...although VERY flexy Anybody got any idea of weight on these? significantly lighter than a tryall? same material as an echo 07? I wouldn't consider myself a basher....but I'm sure someone who i ride with will be able to voice their opinion on this...
