Just finished fitting Matris cartridges to the customer R6 I build from scratch (thread here: http://tarmactalk.com/forum/showthre...ew-to-racebike ). I've gotta go on record again with just how fabulously good the Matris stuff is! The machining, build quality and tolerances are simply beautiful, and the end result is an absolutely fantastic feeling fork. Top stuff.

Pics of the difference between the Matris compression piston and the OEM piston (each side).
