Ok guys I took the frame to West End Cycles here in Houston ( thats where the mountain bike gurus live) and was told that the Ritchey conterfit is actually a Diamondback WCS that was made in cunjunction with Ritchey. Made inline same tubing as the P-20. Bad news is that the gusset at the downtube is not original, so it's been fixed or just beefed up. Anyway does any one have a picture of a Diamondback World Champion WCS ??
