Top tube measurements are given in both actual (c-c) and effective (true measurement of the size of the rider compartment). Top tube is level on XL.
Standover height changes significantly with tire size and fork choice; our measurement given is from top-center of top tube to the ground using our supplied fork and a pair of relatively large Tioga DH 2.1 tires that measured 676 mm in diameter on our rim.

Every frame has 135 mm rear spacing and long horizontal dropouts.

Every frame uses a 27.2mm post.

Every frame uses a 30.0 mm seatpost clamp.

Every frame has a 73 mm English b.b shell.

Every frame includes a beefy, suspension-corrected rigid fork.

Every frameset will fit tires up to 2.7" wide.

Every frameset features 100% cro-moly construction; the front triangle is double-butted.

CROSS-CHECK ® FRAME SPECIFICATIONS

Tubing:

100% Surly 4130 Cro-moly steel. Main triangle double-butted. TIG welded.

Rear Dropouts:

Long horizontal dropouts with adjusters feature single-speed compatibility, wheelbase adjustability and our exclusive Gnot-riteª 132.5 mm spacing to easily fit 130 mm road or 135 mm MTB hubs.

Braze-ons:

Cantilever bosses front and rear, fender eyelets front and rear, and dual water-bottle mounts. Down tube shift cable routing.

Seatpost diameter:

27.2mm

Seatpost clamp diameter:

30.0 mm Surly Constrictor™ included.

Headset:

1 1/8” threadless.

Bottom bracket shell:

68 mm wide, threaded English 1.37x24t.

Tire Clearance:

Proprietary FFFª (Fatties Fit Fine) chainstays and our custom fork give room for tires up to 700x45c with mud and fender clearance left over. Seriously!

Chainring Clearance:

Though we haven't yet tried a '56', we manipulated the chainstays heavily so you can fit whatever size rings you want, so go for it!

Color:

Blood Red and Jet Black.
