If anybody actually ever bought the Rivendell Speedblend tires, (for which GP actually sought and got a patent,) they'd be a strong contender.

Also, they'd be in medal contention for "dumbest idea in the history of bicycles"... especially because they almost bankrupted the company, and literally everyone was telling Grant, "Dude, those tires are stupid and ugly and nobody will buy them."

PS: All that said, on an early 90s MTB with a screaming neon paint job and hella anodized parts... I'd rock a set...
