That mtb is lush! XTR too, very nice, although a little clean!
It is indeed.
Spec: Litespeed Occoee frame, handbuilt wheels (DT240s hubs, DT 4.1d rims, DT Revolution spokes), Full XTR drivechain, Easton EC90 bars, FSA K-Force Seatpin, Avid Juicy Carbon brakes, Magura Durin 100mm race forks, Schwalbe Racing Ralph Evolution Tyres, FSA XC115 Stem, Fizik Gobi saddle. All up weight is sub 19lbs.
This was my dream bike back in 2007 when I built it specially for competing in Trailquest/MTB Orienteering events. Sadly it gets little use now and I would sell it if I got a sensible offer (original cost was upwards of £3,000).
