COVID-19 Important collection and delivery information
Due to a combination of new working practices and demand our lead times for both collection and delivery have been extended.
Where delivery times are stated as a month this is based on the latest information from the manufacturer. These dates should be treated as a guide and may be subject to change. Due to an increase in global demand for bicycles and the disruption in supply during the COVID-19 pandemic supply chains have become very strained. Lead times are based on factory and shipping schedules both of which can be disrupted by delays in component supply and shipping/port capacity.
Should you place a future order with us for a bicycle we will monitor the bike’s ETA and keep you informed of any changes.

This Cannondale SystemSix HiMod Ultegra Di2 Mercury 2021 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 Hi Mod Ultegra Di2 features a high modulus carbon fibre frame and fork. This higher modulus carbon fibre offers a better strength to weight ration than the standard carbon fibre allowing for less weight and better stiffness. The HollowGram 64 KNØT wheelset and KNØT systembar work seamlessly with the frame for the best in integrated aerodynamics. The Cannondale SystemSix HiMod Ultegra Di2 features Shimano's venerable Ultegra Di2 components for awesome gear changing and a superbly clean setup. Dura Ace 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. Cutting the 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 pedalling 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 Hi Mod Ultegra Di2 is hard to beat.
Please note: This SystemSix features a unique handlebar and stem design. Fitting an adjustment information can be found in the SystemSix manual Manual (external website).
IMPORTANT: This bicycle is supplied without pedals. Pedals for this bicycle can be selected for no cost using Podium Points™.

Sizing information is provided as a general guide only. This is based on the average rider riding the bicycle in the style for which it is intended. This takes no account of a rider's personal proportions, physique, flexibility and biomechanics. If your height places you on, or near, a bicycle size step then we recommend you consider both sizes. All bicycles offer a range of handlebar and saddle adjustment which will enable you to fine tune your riding position once the correct size has been established. If you are unsure on sizing, we strongly recommend you visit our store so we can assist you. Pedal On offers advice and information on sizing in good faith, the final decision and responsibility on which size to purchase is yours.
