Following on from the other thread, keen to see your decent HTs.
Just spent a fair bit on mine so it's now about 22lbs (new brakes, entire drivetrain, rear wheel, already got lots of lightened parts from when it was standard – 2007 Stumpy Comp HT) and I think I'll leave it there but I definitely have a bit of MTB spending/lightening "illness" about me.
This is just before the new rear wheel went on two days ago (replaced with Hope Pro 2 hub, Mavic xc717 rim) – that shaved a bit more weight off. It's lifted the bike from "pretty good" to "very good" IMO.
Also – how often do you lot kill drivetrains? I'm on my third (cassette, chain, chainset, BB) now – one a year!
