Chinook Travel Lite: This is one fast road tandem. It features 30mm wide, 56mm deep carbon rims that pair beautifully with the “28mm” Continental GP4000S II tires for a low drag, low resistance wheelset. SRAM Red eTap shifting with Cycles Chinook x Digirit extended derailleur cage for use with an 11-42 cassette and WickWerks 53/34 chainrings. Full hydraulic disc brakes clamp onto 203mm floating rotors. With two sets of couplers, this bike could be stealing KOMs all over the globe.

Romance 3192: 3″ tires, 2 dropper seatposts, SRAM Eagle 1×12, flat bars. This off-road machine has a suspension-corrected rigid fork and a 110mm travel RockShox Pike.

Chinook Gravel/Travel Lite: The owners of this bike have had a tough time fitting comfortably on tandems in the past. On most standard geometry tandems with 28.5″ boom tubes, this pilot’s seat is exactly where the stoker’s handlebars need to be. We made some calculated adjustments give them each some room. The result doesn’t look like an off-the-shelf bike, but it fits this duo perfectly. This build uses lightweight Lightning cranks, Gates belt, Deda carbon handlebars, and SRAM Red eTap wireless shifters with hydraulic disc brakes. The titanium frame and fork have Boost thru axles and clearance for 27.5 x 2.0″ tires. It weighs 30.5lb with 2 sets of couplers.

Chinook Open Road: This tandem offers versatility, dependability, and performance. The titanium frame and fork have mounts for V-brakes and 203mm disc brakes. The complete bike packs compactly with 2 sets of couplers and 4 cable splitters. Boost thru axles front/rear. Clearance for 700c x 51mm tires or 650b x 55mm (using disc brakes only). SRAM Force 22 mechanical group with 52/36 x 11-40 gearing. SRAM Rival cranks (modified for crossover drive). Primary V-brakes plus rear disc drag brake.

Granite Travel Lite: This build had the intention of enjoying every trip to the fullest. The coupled titanium frame can pack into two S&S airline accepted cases [meaning you don’t need to pay extra luggage fees for traveling with your tandem]. Each component was carefully selected for it’s performance and value, making the tandem light, responsive, and fast.

Time Traveler.  Designed specifically for a Race Across America team member that plans to time trial across the country AND travel with his family afterward. The stoker is an accomplished athlete who also happens to be blind. This specific geometry allows for multiple caption positions, optimized for different types of riding. Just because you plan to time trial across America, doesn’t mean you won’t want to ride the bike for fun after!
