I happen to have just posted a rear Corima 4-sp tubular in the classifieds with a Vittoria Corsa CX (only ridden a few times on the tire--like new), with a skewer & cogset--race ready. It's glued on already. IF you wanted to take advantage of the "decline" you say, in tubular prices or popularity. Wheel is in really good condition, I only raced on it. 700cc. Shimano style hub.
