50mm Tire Clearance
The Big Adventure Tandem sports a rugged platform design around 50mm of tire clearance. With more pneumatic suspension and more traction, there isn’t anywhere the Big Adventure can’t go.
Molded Chainstays and Seatstays
The Big Adventure Tandem utilizes molded chainstays and seatstays derived from our Cephal mountain bike to offer a more comfortable and controlled feel over harsher terrain. The layout is designed to be vertically complaint, yet torsionally stiff, offering a supple rear end feel that doesn’t compromise pedaling performance.
The Big Adventure geometry is designed around our pre-existing Adventure geometry, but with a few significant changes. Slacker angles and minimized toe overlap means that this tandem rides more confidently than any other tandem we’ve ever produced. Check out our updated geometry here.
Utilizing S&S couplers, you can now conveniently travel with your tandem to wherever your adventure takes you. We incorporate couplers directly into your tubing, allowing you to split up your tandem into two or three separate pieces. When you’re piling your tandem into the back of your car for a road trip, or traveling half-way across the globe for a race, the coupler design makes your adventure just that much more travel friendly.
Our expert-selected build kits utilize your favorite components from the likes of SRAM, Shimano, Campagnolo, and more to deliver a well rounded package while eliminating the guess work related to tandem construction and specifications. Each unique build kit is thoroughly tested to ensure maximum reliability and performance. See available build kits for this model.
