Favero Assioma PRO RL-1 Road Power Meter Pedals

The Favero Assioma PRO RL-1 Road Power Meter Pedals bring Favero’s latest PRO spindle technology to LOOK KEO users. Like the popular RS-1, the RL-1 uses a clean podless design which lowers weight and shields the internal electronics. As a result these single sided pedals weigh just 130 grams per pedal and stand among the lightest road power meter pedals available.

In terms of fit, the RL-1 runs a 53 mm Q factor and a 10.5 mm stack height, which closely matches standard road pedals an promotes a natural pedaling position. The large 755 mm² contact surface area ensures maximum power transfer. Unlike other LOOK KEO compatible power meter pedals, the RL-1 lets riders dial in the release tension via an adjustment screw. Installation takes only minutes and you can move the pedals between bikes without hassle. Therefore they suit riders who want one reliable power meter for multiple bikes.

For performance, the Assioma RL-1 pedals are +/- 1.0% accurate and include advanced metrics such as Power Phase, Pedal Smoothness, Torque Effectiveness and Platform Center Offset. Meanwhile a rechargeable battery provides up to 160 hours of ride time. Finally, Favero supports the pedals with a full two year warranty for added confidence.

Power Measurement

These pedals are single-sided and measure power from the left leg.

Compatibility

This power meter is compatible with LOOK KEO and KEO Grip cleats along with any bike. See Compatibility tab for more information.

Considerations

These pedals are designed for LOOK KEO cleats and won’t work with Shimano SPD-SL cleats. Fortunately there is a SPD-SL version called the RS-1.

Advice From Our Staff

Favero continues to produce accurate, reliable, lightweight and good-looking power meter pedals. The PRO RL pedals use the same technology as the PRO RS road pedals which have been one of our top-selling power meters. Because these are single-sided power meter pedals, they are also very affordable. If you are looking for a road power meter pedal for LOOK KEO cleats, the RL-1 checks every box you could want in a power meter pedal.
