Hell yes will the fattest rubber be cushing mine...and less man/girly sexism please
I got an reply from Surly when I enquired about whether the Straggler would be any different than the CC in terms of tyre fit, and whether I'd get away with Schwalbe Big Bens (50mm) on Velocity Blunt 35s and whether they'd do any measuring of tyres/rim combinations like they did for the Knard 29 x 3 or snap some pics of fat rubber in situ... I quote their fairly predictable (going on Cross Check knowledge etc) reply:
"From the website: Fatties Fit Fine (FFF) stays and our beautiful slope-crowned custom fork provide room for tires up to 700c x 42mm, or about 700c x 40mm with fenders. Largest possible tire size depends on tire, rims, axle location in the dropouts, and other factors, but still, you can run pretty damn big tires. It’s pretty tough for us to have measurements of every tire on every rim combo, but the Knard is a 41mm casing, and it’s pretty spot on 41mm. We have max tire clearance listed for all of our frames on their respective product pages, but spoiler alert: you can run a Knard with 45mm SKS fenders with the wheel all the way back in the dropouts. The Straggler tire clearance is the same as the Cross Check so if you have a Cross Check already, you can pretty much count on the Straggler being a whole lot like your old Cross Check."
