This photo from Ken Denny's current auctions shows a Clément Grinta cross tire. When I bought my Cinelli it had tires labeled Clément Grinta that didn't have the conspicuous "knobs" present on the tire pictured, but rather a deep indented tread. I was told by the fellow who sold me the bike these were off season training/wet weather tires which is what they looked like. Was the Grinta a line of tires rather than a specific pattern?
