Oakley factory Pilot gloves are pretty good. Mine are 2 years old and just starting to go at the seams.
Nobby Nics (all versions, not the first thing to come off of a new bike),
Superstar Laser Chain device (their other chain devices were fine but I could not get this to fit anything without taking a hacksaw to it),
Tioga Factory DH Tyres (like riding on ice),
Renthal Kevlar Lockon grips (ok but not very comfy, not very hard wearing, ugly colour and expensive),
ISIS Hussefelt Cranks,
Norco Atomic,
