Following on for the what car thread, I thought I'd start one for mountain bikes. I've included what I've owned since I got back into riding as TBH I can't remember exact the make and model of old stuff.
1996 GT RTS
1998 GT LTS 2000DS - with Rock Shox Judy XL triple clamp forks! I thought I was Mike King or Steve Peat on this!
1998 Specialized Stumpjumper M2
1999 GT Zaskar - custom build with LX. Mavic 521 rims and Rock Shox Judy 100 forks. Wish I still had it.
2002 Santa Cruz Superlite - LX/XT, Hope XC4's, Rockshox Dukes, Easton finishing kit. Now my dad's bike.
2000 Gary Fisher Supercailiber - Ex magazine review bike, bought cheaply direct from Trek when I worked in a bike shop. Full XTR, Manitou Mars Carbon or Marzocchi Marathon forks. Approx 22lbs. Fast but a bone shaker, XTR V-brakes don't seem as good as they used to!
2004 Intense Tracer - Fox Float 130 forks, LX/XTR, Hope Mono Minis, Gold Pro Taper bars! Still rides really well, much tricker than the Specialised FSRs that donated the four bar rear suspension design.
1998 Intense Uzzi SL - frame only at the moment, most bits went on the Tracer. Was my dream bike, but the bottom bracket always seemed too high to me.
1999 GT I-drive 1000 - In bits at the moment.
2005 Kona Kula - Easton Ultralight frame, Fox Vanilla forks, Hope X2. Light and responsive, doesn't beat you up as much as older alloy frames, it's my main bike for the winter.
2008 Rocky Mountain Slayer SXC 50 - Stock build with Fox Float 36's, SRAM X9, Race Face and Avid bits. Absolutely fantastic 6" travel bike, pedal well and only feels heavy when lifting it over things. The maple leaf red and white paint job is too nice to scratch so doesn't see much mud!
