i don't know if they stopped making them, but they're certainly still shipping them to shops (as recently as last week, at least).
though honestly, unless you're taking the bike offroad why not go with dura-ace or campy record? cost a little less, lighter, smaller stack and just as smooth.

unless you're after colors, in which case ck is the only game on the block (a very good one, at that).

ps, here's the product page. at the bottom is contact info... give them a quick call to double check. conference trackstar in so they don't misinform any more customers.
