The 2INpower SL will allow you to get accurate power data from each leg independently, to comprehensively analyze all your data. Use data like torque effectiveness, pedal smoothness, balance, TORQUE 360, OCA and OCP to have a precise biomechanical control of your pedaling. ROTOR chainrings, compatible with Shimano(R) 11 and 12 speed groupsets, incorporate an aerodynanmic design that improves air flow. Their optimized sprocket set allows fast and precise shifting in any situation, while the new architecture improves their structural rigidity, which is why they are the preferred choice of the most demanding cyclist. In addition, if health and/or performance is important to you, Q Rings oval chainrings should be your choice over round chainrings. Thay will allow you to pedal more efficiently, making the most of the power generated during your pedaling while reducing the stress on your knees, giving you a healthier pedaling experience.
