About the SRM ROTOR 3D+ Power Meter

Meet the new SRM ROTOR 3D+ power meter! Offered in both 3D and 3D+ options, the cranks on the SRM ROTOR power meter are created using the Trinity Drilling Process. Three holes are drilled end to end, length-wise, through a solid piece of aluminum. This creates a lightweight, but very strong crank – which is what ROTOR is known for. Add in SRM’s best in class accuracy and you have a power meter to be reckoned with.

In addition, the SRM ROTOR power meter allows a high degree of compatibility between frames. The ROTOR 3D+ model allows for direct integration into BBRite and BB30/PF30 framesets. The ROTOR 3D models allows for compatibility with standard BSA as well as press-fit BB90 frames.

Please note that ROTOR Q-Rings (pictured) are available as an option for an additional cost. All ROTOR SRM power meters come standard, round rings.

    Great sales support and fast shipping from Power Meter City! Josh contacted SRM to ensure I was getting the right product and then followed through on every detail, including delivery and installation! The power meter came with excellent instructions and everything I needed to install at home! Nothing like SRM quality and precision too! Thanks!
