What power meter for ROTOR 2D, 3D series or FLOW cranksets?

The ROTOR 2D, 3D series and FLOW cranksets are an older generation crank, so there are not many power meters for them. Fortunately however, there are a couple of options. Let’s check them out.

Spider Based Power Meter

Sigeyi AXO ROTOR 3D Road Power Meter

The Sigeyi ROTOR 3D Road Power Meter is a spider-based power meter that is made specifically for the older generation ROTOR cranksets. This includes the ROTOR 2D, 3D+, 3D30, 3DF, and FLOW cranksets. It bolts directly onto your cranks, so there is no need to change cranksets or bottom brackets. In fact, in most cases you can reuse your existing 110×5 or 110×4 chainrings. The Sigeyi measures power from both legs, is accurate to +/- 1.0% and is lightweight at only 105 grams.

Power Meter Pedals

Power meter pedals can be installed on any crankset. They are reliable, accurate, easy to install and can be moved between bikes. We carry every power meter pedal available including ones from Favero, Garmin, SRM/LOOK and Wahoo. This includes both single- and dual-sided versions as well as pedals for SPD-SL, LOOK Keo and Speedplay cleats.

Cons: None
