It took its technical and design cues from ROTOR's existing POWER LT cranks but instead of measuring power metrics in the left crank arm, POWER LT-R records data from the right side. POWER LT-R was created in response to customer demand for a power meter that measures data on the drive side. POWER LT-R was the result of a collaboration with UCI Pro Team Lampre-Merida, which compelled ROTOR to come up with a simple, lightweight power training system that could withstand the rigors of punishing use by the best professional riders.

POWER LT-R is based on our race-proven 3D+ crank. It is one of the lightest power measurement systems on the market.
