Here's my 2005 Trek Fuel 80 with the Disc Brake package and RockShox Pilot SL fork. I absolutely love it. Not exactly a race bike, but best bike I've ever owned. I've upgraded the disc brake pads to EBC, and that's about it. I'm shopping for a larger rear disc rotor since bombing downhills tend to wear out your fingers. The Hayes Nine hydralic brake package is sweet, and really light at the levers, but constant rear braking is a little too much for the stock 6" rotors. Also the Pilot SL forks are getting pretty beat up, so an upgrade to Psylo or Manitou Elite might be in order.
