The Domane might actually be embracing the trend toward larger tires. Longer chainstays, etc. That would be cool. I'd still have to see it to believe it. The Trek store guy told me it (Domane) wouldn't fit a 28 but I'm pretty sure he had not tried it. I troll ebay and craigslist for a Roubaix mainly because it has more clearance. But I've been universally disappointed with tire clearance on the dozen or so road frames I've played with. I have converted two of my LeMond frames to 650B rims just to get clearance for 32's. And even with 650B rims, I can't get any wider than 32.
