This is my "rest of life" mountain bike - a gradual evolution of bits and pieces that have travelled some way with me and ended up staying because they're so good. It's very light, very fast, very comfortable and should last forever - although I read about a cracked Global TH1.5 frame last week so now I'm not so certain. A bike like this is easy to carry up mountains, fast and reliable on a long mountain day and a good deal less tiring than a heavy FS rig. The weakest point is those Hope wheel bearings, which do seem to need replacing every couple of years. It has thumbshifters too, dinky little Suntour XC Pro jobs, which can be indexed or friction so are perfect for reliability in the field.
I don't plan on changing much on this bike, it should do me now until I can't ride any longer. It won't get much use anyway because I've gone over to the more subtle delights of the road though it will be out in the snow this afternoon!
