Ride Where the Pavement Ends
If you only have room for one bike in your life, Straggler can (and should) be your one and only.
A decade-long hiatus taught us there’s more work to be done when it comes to resplendent riding on unpaved terrain. Thus, the new Straggler emerges with a dialed-in fit range and comfortable geometry, ready to roll with thru-axle wheels, flat-mount brakes, and zero ego.
It's a bike down for a lot of stuff, but it really shines when it’s kicking up dust to help you blow off some steam and get back to those dirt roots. No more missed opportunities or dead ends –– the Straggler’s taking every rowdy detour or weekend rendezvous it can get. It’s the ultimate day-tripper, cross-terrain explorer, and boundary-pusher, ready for you to plow through challenges, not obstacles.
Straggler’s capabilities extend into some light cargo setups, so you can do double-duty when hitting the trails and running around town. Tack on one of our Pack Racks and maybe a frame bag when you need to grab some groceries on the way back to civilization –– knowing with Straggler, you always have an exit plan.
- 650b or 700c wheels (varies by frame size) for optimized rider fit
- Racks and fender mounts, plus two standard and one three-pack bottle mounts on all frames
- Updated thru-axle dropouts for improved stiffness and handling
- Modern flat-mount brake mounts, internal dropper routing, and 44mm headtube
- Lower bottom bracket and sloping top tube adds stability and better standover
- 50mm tire clearance w/o fenders on 700c for confident, comfortable riding on eroded terrain
