Velo-Perso.com Opinion:
"The Rotor 2INpower SL Aero is the most aerodynamic crankset in Rotor's range, featuring dual-sided power measurement and a relatively low weight. This is the best dual-sided power meter crankset we offer for a double chainring setup, allowing you to compete with some single-chainring TT cranksets thanks to its highly refined aero shape while maintaining the flexibility of a double chainring setup."

Perfect for triathletes and time trialists looking to maximize speed on flat terrain and rolling hills, the 2INpower SL Aero crankset offers a versatile and high-performance solution. Its aerodynamic design and precise power measurement make it an excellent choice for serious cyclists aiming for peak performance.
