The all-new 2019 Cannondale SystemSix Hi MOD Ultegra Di2 was created with one simple goal in mind — to make the fastest, most rideable, most aerodynamic, most holistically integrated piece of high-velocity bad-assery ever. Ballistec high-modulus carbon is precisely shaped to give the SystemSix its slippery profile, with further wind-cheating advantages supplied by a fully integrated stem, fork, and seat mast.
