The CDLV 650b tire is what I've ridden for years. Very happy with them, especially in view of the price they sell for. After 3 years they're starting to show their age, though. Rivendell shows them as discontinued. Does that mean only that Rivendell's stopped stocking them or that the tire is no longer made? If anybody knows I'd appreciate the information, as I'd buy a new set before they disappear from the market altogether. Otherwise I'll ride the ones I have until they threaten to fail.
