"Cannondale reckons that the aerodynamic performance of the SystemSix will benefit you in these ways:
• Riding solo or on the front of a group at 48km/h (30mph), the SystemSix will save you more than 50 watts compared to a lightweight (non-aero) road bike.
• Drafting behind another rider at 48km/h (30mph) saves you 30 watts compared to a lightweight road bike.
• At a speed of 30km/h (18.6mph) on a flat road a traditional road bike requires 140 watts while the SystemSix will save you around 10% power at that speed.
• In a 60km/h sprint over 200m, Cannondale’s notional rider on the SystemSix will save 0.4secs over an identical rider putting out the same power on a SuperSix Evo, finishing 7.2m ahead.
• Pedalling down a 5% gradient at 200 watts will get you to 60.6km/h on the SystemSix. According to Cannondale, you’d need to put out 309 watts on the SuperSix Evo in order to match that speed. That’s a huge difference.
• The SystemSix will save more than 50 watts over a traditional lightweight bike at 48km/h (30mph), 13 watts over Specialized’s Venge Vias 11 watts over the Cerverlo S5, and 6 watts over the Trek Madone, its nearest competitor.
As mentioned, these are all claims from Cannondale."
Unusual for a bike company to be so specific with their savings and competitor comparisons?
Obviously dependent on component choices etc.
Points 3,4,5 are quite interesting, not so much Cannondale specific, but the benefits of aero bikes compared to standard.
