The fastest road bike in the world. If you like to go fast, the all-new SystemSix will make you faster. It’s as simple as that. The result of years of incentive R&D its fully System Integrated design delivers more speed, in more situations, than any other bike on the market.
To sum it up: It’s the fastest UCI-legal road racing bike ever made.
Highlights:
- Go Faster. Easier. SystemSix produces the least aerodynamic drag of any road bike on the market. Since the bike represents about 30% of a riders total drag, that translates into less effort for any rider, at any speed.
- Faster on Climbs. The SystemSix’s aero advantage make it faster than lightweight climbing bikes on any climb up to a 6% gradient or more, depending on rider’s power to weight. To put that in perspective, the most revered HC climbs in the Tour only average 7-8%.
- Faster on Descents. Dropping down a 5% grade, a rider on a traditional lightweight bike would need to put out over 300 watts just to keep up with a rider spinning at a recovery effort on a SystemSix.
- Faster on the Flats. At 48km/h (30mph), 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 drafting, you’re still getting up to 60% of that benefit.
- Faster in the Sprints. N a 200m sprint with riders putting out a 1000 watt effort, the SystemSix rider would be four bike lengths ahead at the line.
Easier when Cruising. Even at a mellow group ride pace, SystemSix requires about 10% less power to maintain speed, leaving you with more in the tank when it’s time to throw down.
