Anybody using 25 mm GP4000s on a 2011 Cervelo R3...?
I think it's a 2011, it's the first year the frame used BBright.
I just mounted my last spare tire on my rain bike, and need to order more. I've been thinking about trying 25s, since I've been running 23s for years. Better comfort shouldn't hurt, and it seems like they'll have a little bit better grip through tight corners coming down mountain roads.
When I got the bike, LBS told me clearance for bigger tires was dicey, and it depends which particular tires.
Any experience with this?
