Key features of the Cannondale Synapse Hi-Mod Disc Ultegra are a high modulus carbon composite frame and fork, carbon composite C-Zero wheelset, Cannondale Hollowgram Si chainset and a Shimano Ultegra 22 speed groupset.

The awards say it all, Cannondale's Synapse Carbon bikes set the standard for endurance road bikes. Voted Bike of the year 2014 (Cycling Plus) and Bike of the Year 2015 ( the Synapse Carbon's amazing ride quality and lightweight makes it a brilliant all rounder, comfortable AND fast. At the heart of every Synapse Hi Mod is the SAVE Plus micro suspension system which uses different carbon layups in the rear triangle, seat tube, seat post and fork to each damp out vibrations of different amplitudes. Hi Mod frames use very high modulus carbon fibre which has a higher stiffness to weight ratio than the carbon used in the standard carbon frame allowing Cannondale to build a lighter, stiffer and stronger frameset. Further frame features such as the Power Pyramid seat tube which splits into two tubes above the bottom bracket to maximize stiffness whilst keeping weight low.
Synapse Carbon bikes have Endurance Race geometry. This is based on the race geometry of the Supersix EVO but uses a taller headtube, slacker head angle and longer wheelbase to give a slightly more relaxed ride whilst retaining a performance position.

The Cannondale Synapse Hi Mod Disc Ultegra uses Shimano's venerable Ultegra groupset. Shimano's Ultegra groupset offers pro level performance at a sensible price point. Accurate, reliable and precise it does everything you want from a groupset whilst keeping the grams to a minimum. The Cannondale Hollowgram Si 50/34 BB30 chainset is super lightweight benefitting from hollow crank arms and the super stiff and light oversized BB axle. The Hollowgram Si chainset mates with a 11-32 cassette giving a wide enough gear range for any situation.

Shimano's R685 hydraulic disc brakes are some of the very best around. Neatly integrated into the shift levers and with compact calipers the R685 brakes offer the usual Shimano light action at the lever for excellent stopping power at the wheel. Their modulation is excellent and the confidence they give, particularly in wet conditions is invaluable.
Cannondale's own in house C Zero wheels are used by the Synapse Hi Mod Ultegra. These feature a composite rim and sealed bearing 28 hole hubs. Weight for these wheels is a very svelte 1367 grams.

If you are looking for a near perfect do it all road bike with a superlight frame and fork then the Cannondale Synapse Hi Mod Disc Ultegra is it.

IMPORTANT: This bicycle is supplied without pedals.
