Surly Framesets | Bridge Club 27.5"/700c

All Road Touring Bike for Any Destination
Bridge Club is for those multi-surface outings — planned or unplanned. We've all run out the clock on a dirt tour and had to add in some paved shortcuts. Conversely, when you’re feeling a little zesty on your next road tour, Bridge Club is ready for reroutes through the woods.

Some people hear "bike touring" and immediately think of long-forgotten stretches of highway, small-town oddities, and roadside attractions. Some instantly recall desolate stretches of desert dirt roads or lush green forest trails. With Bridge Club, you can have your dessert and eat it too!

• Ultra-focused on simplicity, it only has the barnacles that matter most to the discerning bike tourist
