The SRM Rotor 3D+ PowerMeter is a well-loved classic. Durable and with an incredible stiffness to weight ratio thanks to Rotor´s “Trinity Drilling Process”.
With its 30mm spindle, the Rotor 3D+ allows for direct integration into BBRite and BB30/PF30 framesets.
The SRM 7th Gen. PowerMeter can be chosen in the rechargeable version or with the durable battery.
The standard version is compatible with 53/39, 54/42 and 55/42 chainrings.
The picture shows the compact version (BCD 110mm) of the PowerMeter and is for illustration purposes only. The standard version looks different but offers the same functionality with a BCD of 130mm.
