Simplicity and utility: the core values at the heart of Surly’s all-road touring frameset, the Bridge Club. Robust, repairable 4130 chromoly tubing is fitted with all the mounts you could ask for, whether you’re running guards, panniers, bikepacking bags, cargo cages, or the whole lot!
Wheel choice? Take your pick – Surly’s “Gnot Boost” rear axle spacing allows for conventional or Boost wheels with a quick release, and the frame and fork are happy with up to 26” x 3.0”, 27.5” x 2.8” or 700 x 47mm. The Bridge Club is equally capable tearing up a deserted highway across the States as it is trundling up and over the South Downs. Tune the ride to suit the trip.
