Even more stamina! Whether you're on group rides or take the detour on the daily commute with the little bit of extra comfort, the Synapse Alloy Disc is made to enjoy kilometers. At the same time it is the first Cannondale road bike equipped with disc brakes, which provide strong braking power and perpetual control. The Synapse Endurance Geometry meets with a slightly higher head tube, a slightly longer wheelbase and a slightly shallower steering angle, the ideal balance between pure racing upright position and comfort. 24 km routes across hell? The Synapse is the ultimate partner for an unprecedented journey! The craftsmanship that Cannondale put into their frames is unrivaled. The Optimized Alloy Frame with its true smooth welds help to create a stronger, stiffer frameset. The so-called SAVE PLUS aluminium allows the rear by flattening and butting the chainstays and seatstays to vertical flex and absorb the bumps and vibrations of the road. At the same time a high lateral rigidity for optimal power transfer and cornering ability is maintained. The fork with carbon blades and integrated SAVE components allow an extra comfort and precise handling. In addition, the frame provides the ability to mount fenders. Completely new SRAM Rival 22 components guarantee smooth and durable shifting and braking performance over years. And with fenders in the frame colour the "ride" remains an experience even in the rain. Why disc brakes on a road bike? No rim wear (the wheelset will last longer) No pressure changes inside the tire due to temperature change while braking Same braking performance in any whether condition Less rotating inertia (rim weight saving) Can run even on a non-straight rim (i.e. spoke failure) History of MTB already tells the way to go...
