Co-Motion has listened to their riders faithfully over the years, introducing tandems that suit the terrain that riders enjoy. The Java is an excellent example of that, allowing tandem couples to explore off road as well as on.
The Java is an off-road touring tandem, with room for 29'er tires up to 2.0" wide. A long wheelbase and stable geometry brings confidence when plowing through gravel and singletrack. Handbuilt with butted chro-moly steel, the frame is strong enough for loaded touring with powerful riders aboard. An oversized 44mm head tube anchors the fork, improving handling and braking, especially at high speeds. Thru-axles front and rear ensure perfect hub and brake rotor alignment. The Java's rack and fender mounts -along with 4 bottle mounts- ensure you don't leave anything behind on long trips!
Co-Motion installs Shimano Ultegra 11-speed components at the Java's drivetrain, with the front derailleur, long-cage rear derailleur, dual control levers all working together for instant gear changes and long service life. An alloy 50/34T compact crankset and 11-34T Shimano cassette adds a 1-to-1 ratio for fearsome inclines when loaded down with touring bags.
Reliable wheels are important to every tandem, and Co-Motion didn't scrimp on the Java's setup. Handbuilt 40-spoke alloy Velocity Cliffhanger 29er rims are laced to Co-Motion's own Boost110/148 hubs, making the Java more than ready for singletrack. Knobby Vittoria Evolution 29 x 1.9" tires come stock, and boast bags of grip on unpaved surfaces. The Java's brakes are well engineered for high speeds in every environment, with cable-operated TRP Spyre disc brakes coupled with meaty 203mm rotors.
For the Java's "furniture", Co-Motion chose FSA's alloy Omega compact road handlebar for the captain, and an alloy Co-Motion stoker bar for the back-seater. An alloy FSA Gossamer stem up front and an adjustable Co-Motion stoker stem makes a comfortable fit easy. Selle Italia's XR Flow saddles soak up impacts well on rough and choppy surfaces.
The Co-Motion Java is available in Small, Medium and Large. Custom colors, geometry and component choices are also available, including a Rohloff internal shifting rear hub, or Pinion P1.18 internal gearbox, both with carbon Gates drive belts replacing the chain. Please call for details.
