The most obvious difference of course is that the Straggler has disc caliper mounts instead of rim brake studs. It’ll accept rotors up to 160mm. The rear dropouts are unique, too. They’re a partially closed horizontal design that accommodates singlespeed or geared drivetrains. They feature stop screws that thread in from the rear to further secure the wheel and to position the rear wheel for optimal shifting, plus a forward-mounted stop screw on the drive side to keep the wheel from slipping forward under the force of your gargantuan legs. The rear dropouts are spaced 135mm instead of 132.5mm like the Cross-Check simply because there are far more options for disc hubs in this spacing.

Straggler shares all of the Cross-Check’s braze-ons for fenders, racks, and bottle cages. The Straggler’s geometry is slightly different, with angles and tube lengths very close but not identical to the Cross-Check, but like the Cross-Check, it’s ready to take you just about anywhere. It’s a day tripper and a weekender. It’s a ‘rough road’ road bike. It’s a cyclocross bike with no pretense of racing. It’s a utilitarian townie. It’s a light-duty touring bike. It’s an all-weather commuter. And when you get tired of one setup, you can swap parts around and turn it into something else. We think that’s pretty neat.

Sizing Guide:

When choosing your frame size you should take into account that Surly does not measure the seat tube specifications to the end of the seat tube. For frames with struts on the top tube, this is measured from the middle of the bottom bracket to above the struts. For frames without struts, measure from the middle of the bottom bracket to the top edge of the top tube.
