Favero Assioma PRO RL-2 Look KEO Power Meter

The Favero Assioma PRO RL-2 is the dual-sided Look KEO flagship of the Assioma PRO series. Both pedals measure independently and therefore deliver a much deeper data base for power, balance, and pedalling technique. If you want to enter the PRO platform at a lower price, the Assioma PRO RL-1 is the direct entry version.

Unlike the classic Assioma DUO, the RL-2 uses modern spindle-based measurement inside the axle and offers longer battery life. For riders who want to stay with Look KEO while choosing the most modern Favero KEO solution, the RL-2 is the most consistent option.

Why the PRO RL-2 is not just a newer DUO

The PRO RL-2 does not replace the classic DUO only cosmetically, but architecturally. The sensor system sits protected inside the axle, external pods disappear, the design is cleaner, and the PRO platform is built around long runtime and modular use. If you are buying new today and intentionally want Look KEO, the RL-2 is the more modern system.

IAV power technology inside the spindle

Strain gauges, gyroscope, battery, and communication unit are fully housed inside the spindle. That reduces potential weak points and protects the electronics better against water, dirt, and mechanical impact than more exposed constructions. For a pedal power meter, this is a meaningful design advantage.

Replaceable pedal body

The pedal body can be swapped within the PRO family. That means the RL-2 is not just a KEO pedal, but part of a modular platform. For buyers with multiple bikes or changing use cases, this is strategically more sensible than a closed system tied to only one pedal standard.

Cycling dynamics and PCO

The PRO RL-2 transmits Power Balance, Power Phase, Torque Effectiveness, Pedal Smoothness, Rider Position, and PCO. PCO in particular is relevant for riders interested in cleat position, knee tracking, or bike fitting. Anyone actively using these metrics gets much more analytical value than with older Assioma KEO models.

Battery, fast charging, and real-world use

Up to 160 hours of runtime significantly reduces charging logistics. The fast-charge function adds another advantage: 15 minutes of charging can provide up to 15 hours of ride time. That is operationally useful before races, long rides, or spontaneous training sessions.

Compatible bikes and cleats

The PRO RL-2 is primarily intended for road cycling and triathlon. It uses Look KEO compatible cleats and therefore fits riders who intentionally remain in the KEO ecosystem or already own matching shoes and cleats.

Compatible bike computers and smartphones

Data transmission is handled via ANT+ and Bluetooth Smart. This allows pairing with common bike computers and many sports watches. Riders who want the full cycling dynamics in practice usually get the best results via ANT+.

Activation and setup

Initial setup is done through the Favero app. Activation, crank length, and firmware updates are handled there. Especially within the PRO series, keeping firmware current is sensible because Favero actively improves runtime and feature depth.

Warranty and support

Favero manufactures in Italy and provides a 2-year warranty. In case of problems, app-based remote diagnostics are useful because many causes can be narrowed down in advance. That saves time and may avoid unnecessary returns.
