Had an hour or two every few weeks on this, now I'm about 98% of the way there.
Manitou Xvert forks from donor, new decals
Mavic 222 wheelset (much lighter than the 521) from another donor bike
Spesh Storm Control tyres
XT mech, new 9spd cassette/chain and SLX shifter, new BB
Removed front mech rings etc, NW chainring fitted
WTB manganese saddle from donor, light and comfy!
On-one El Guapo kit (so cheap!) Saloon Riser sweep back bars, top cap, seatpost and clamp, kore stem, lock on grips
New Avid SD levers and v-brakes, new cables & outers
Last things to do, fit the Truvativ Husselfelt cranks I got for £15 and get the chain line nice, and then ride it! Been through many combo of bar/stem/saddle but this feels the best combo. Didn't get a chance to weigh but I think it must still be 25lbs ish, feels sturdy but nimble
will have to get used to these wide, swept bars!
