Ha Ha! How long is this thread gonna get? (And how many bikes have some people had!) This is surely the ultimate ME TOO thread..
Well, here we go:
1990 - some cheap mild steel 'Halfords special' type-thing with a plastic rear wheel 'disc' that was my friend's originally, but it fell off my dad's roof rack on the M3 at 70 mph. My dad replaced it with a new bike, and I got the Halfords special. Used for my first forays into the wilds of Surrey
1991 - some cheap-as Townsend - made with Reynolds 501 - woo - it had aluminium rims! Did my first races on this bike, and spent hours of my life cursing its retchedly poor specification and build quality as it greadually fell to bits and I tried to put it back together
1993 - Marin Eldridge Grade - the sweetest cro-mo hardtail ever! Had rapidfire plus shifters and it actually worked and everything. Did more races and started finishing top 3
1994 - Canondale M100 - I decided to upgrade to aluminium as by this point my biking had become *serious*. I did loadsa racing and hours of painful training on this pig-of-a-bike. Rigid as, with a disgusting pant-job and useless 'Canondale Original Design Aplications' (CODA) components, which just fell to bits. It got stolen in 1997, much to my eventual apparent benefit. I've loathed all Canondales ever since.
1998 - Giant MCM Team carbon monocoque (1997) purchased on a whim whilst blearingly hungover one day because I liked the colours - but probably the best decision I ever made. It had done a season as one of the Giant pro-team's race bikes. Lovely bike, soooo, soooo light and my first bike with actual front suspension! I still own it and ride it to this day, and enjoy every moment. I've upgraded most of the bits on it now so that it is a thing of ultra-light retro beauty
2006 - Klein Attitude (2001) frame built up gradually over a summer with old spares and bits off eBay. Intended as a winter bike to stop the Giant from dying. Totally love it though. Beautiful paint-job and a lot of fun. Feels a bit more robust than the ol' carbon Giant. Currently riding (and racing) it here in Tasmania.
...still haven't made the leap to full-sus yet.
