I was going to say Al Carter and scrolled through all the other crap pages just to check it wasn’t mentioned. Al Carter Sidewinder (Pro?), first mountain bike with some “trick components” – had shimano (GS?) “trigger shifters” which were a huge eye opener for me and I rode it miles and miles and miles. When I moved to Grenoble my Mum kindly shipped it out to me. It was largely unloved because I was a cheap-ass student but I spent a whole summer doing 5+ hours a day on it and less than 10 minutes a week looking after it. Looking back I love it now, though I never showed it, and I think it was finally left in the yard of the building I rented the apartment in when I moved on. I’m very very sorry about that.
EDIT : Am now awash with nostalgia. It was obscenely yellow and I’d set off from my apartment, blast up the road to Uriage (past the roadies – it was 20 years ago..) then continue on and hang a right up a mentally steep rocky section that I only managed to get up without putting a foot down about 10% of the time. It was then a run along some fairly fast tracks until I got to the top of a mentally long singletrack back down to Grenoble and then road back across Grenoble to “home”… *sigh*
