My first MTB was a Carerra Quatro Comp GT that had 531 main tubes, I got the frame for £50 off a mate and built it up and raced it, as a junior I was rarely out of the top 5 in local cross country races, so not bad bikes by any account.
Trek, Specialized, Giant, Cannondale etc all make excellent bikes and the name wouldn't put me off any of them.
The current stable consists of a LOOK, Isaac, Van Nicholas, 2 x Specialized (they're twins) and a Roberts that has the original piss take MTB name.
