Intriguing! I'll wait to let Goodyear get some practice in cycling before I buy. I'm sure their compounds are good, but a bike tire is not a car tire. And I'm sure that they headhunted a couple of bike tire designers, but... I think there's a lot to learn. So I'll wait.
But I'm glad to see them enter the market. Pirelli did so too, albeit just for road, I think.
