In reply to Tall Clare:
I was out riding at the weekend on my 1992 Salsa a la Carte. still complete with original tyres (though not very air tight), Suntour XC Pro, middleburn cranks, Rock Shox Mag 21SL Ti forks.
I last rode it in the Brighton Big Dog in 2009, before that I used it for National Points series until about 1995.
My friends were riding their "old" bikes too.... A Fat Chance Yo Eddy, and an Ibis Mojo.
I also have a Cannondale Raven Super V 4000, rare too, in raw carbon, that will be out for a ride soon, that is a 1997 vintage I think.
I've owned both of them from new.
