As a highly versatile touring bike, the Bridge Club hits the sweet spot that separates on- and off-road excursions. The simplistic design makes it fully adept to handle a full rack and pannier setup, frame bags, or any combination of the two. It doesn’t feel sluggish on paved shortcuts, but can also hold its own on dirt detours. If you’re feeling a little zesty on your next road tour, you won’t be ill-prepared for reroutes through the woods. The Bridge Club is designed to handle it all. - 100% Surly Chromoly frame, main triangle is double-butted; 1-1/8" threadless Chromoly fork - Rack, fender, and four sets of three-pack mounts - Disc brake-specific, single-position vertical rear dropout makes it less intimidating than other bikes in the category - Clearance for 700 x 47mm (with or without fenders) or 27.5 x 2.8" tires (27.5 x 2.6" with fenders)

If you do an equal amount of off-road touring as you do hitting trails, Wednesday's ability to play both parts equally will suit you well. Or, if you're looking for a fat bike and don't need the fattest tires on the market, Wednesday's 26 x 4.6" tire clearance is just the ticket.
