RS4x System Cranks
Road double, road triple and MTB
The Rotor System allows the cyclist to spend more time generating power per revolution, whilst generating less lactate.
The benefits provided by Rotor System have been shown in scientific studies to demonstrate a real increase in power of up to 16% (potentially equivalent to an advantage of 3 minutes in an hour on flat ground), as well as a reduction in lactic acid and cardiac effort. Some of the main benefits include increased power, reduction of lactates, mitigation of knee injuries and reduction of cardiac demand. All models are available in steel or titanium versions; titanium model is 90g lighter.
