This Cannondale SystemSix Carbon Ultegra Cashmere 2020 is available with our legendary Podium Point free accessory scheme.

Cannondale's SystemSix is a fully integrated aero road bike system designed for riders who prioritise speed above all else. The Cannondale SystemSix Carbon Ultegra features a Ballistec carbon fibre frame and fork for super low weight without sacrificing stiffness and Vision SC55 Carbon wheelset and Vision Metron 4D handlebar for integrated aerodynamics. The Cannondale SystemSix Carbon Ultegra features Shimano's venerable Ultegra mechanical shifting system for a fantastically precise gear shift and Cannondale's own Si Hollowgram chainset for low weight. Shimano's Ultegra hydraulic disc brakes offer awesome all condition stopping performance and are beautifully integrated in to the SystemSix's frameset.

The Speed of Six. The Cannondale SystemSix is a real example of the whole being truly greater than the sum of its parts. Its greatness was achieved by holding fast to a fully system integrated design philosophy. A six-point approach, conceived to work together as a six part system. Frame. Fork. Seatpost. Bar. Stem. Wheels. Designed holistically to defeat the giant of aerodynamic drag, while delivering the kind of handling, feel and explosive performance you need to make the most of the watts you've got. Because just doing an "aero" frame and fork alone would never have delivered the kind of true results we were going for. And achieved. Simply put, the SystemSix delivers more speed, in more situations, than any other bike on the market.

Cannondale's testing showed SystemSix produces the least aerodynamic drag of any road bike on the market, which is a pretty big deal. Because of all the resistive forces your power has to overcome to make speed, aerodynamic drag is the big dog. Really big. Like, more important in most situations than all the other resistive forces (weight, rolling resistance, bearing friction, etc.) combined. And even in those few scenarios where it's not THE most important thing, it's still a really important thing. So cutting drag translates into more speed, with less effort, in all the places you'd expect. And a lot of places you wouldn't.

Descending a 5% grade at 60 km/h (37 mph), a rider on a modern lightweight race bike, like a 2019 EVO, would need to expend over 300 watts to match a rider pedaling at a 200 watt recovery pace on a SystemSix. Meaning SystemSix riders can truly recover while making others suffer.

The SystemSix's aerodynamic advantage makes it faster than a lightweight climbing bike, such as Cannondale's standard 2019 SuperSix EVO, on any climb up to a 6% gradient or more, depending on rider's power to weight. To put that in perspective, most revered HC climbs in the Tour only average 7-8%.

Compared to a modern, lightweight race bike like Cannondale's SuperSix EVO, at 48 km/h (30 mph), SystemSix saves you over 50 watts - huge savings considering an average Cat 1 racer's Functional Threshold Power is around 350 watts. And even when you're drafting, you're still getting up to 60% of that benefit. If you're not up on watts, trust us, that's more than enough to notice.

If you want a fully featured, cutting edge, aero road bike with a race position then Cannondale SystemSix Carbon Ultegra is hard to beat.

IMPORTANT: This bicycle is supplied without pedals. Pedals for this bicycle can be selected for no cost using Podium Points™.
