Despite being around for 40 years and having a revolutionary impact on cycling training and performance, power meters have yet to become as ubiquitous as other fitness-focused techsuch asGPS head units or heart rate monitors. Historically, this has been down to cost, and many models still push close to four figures. Their designs have also been a limiting factor, particularly if you want to train on two or more bikes.A power meter mountedon a crank arm, crank spider or bottom bracketmay meanyou need to invest in multipleunitsif you have multiple bikes in your collection. A power meter pedal solves this issue.By locatingall ofthe strain gauges and electronics in the pedal,itsnot limited to one bike, meaning moving a power meter between bikes is as simple as swapping a set of pedals. Favero has been promoting the benefits ofa pedal-basedsystem since 2015, and has been manufacturing competitively priced, Italian-made power meter pedals for more than a decade. Enter the FaveroAssiomaPRO The Assioma PRO pedals are based around a modular design. Favero Butnow,intheAssiomaPROrange, Favero has taken things even further, designing a modular systemcentredaround smart spindle technology and swappable pedal bodies. Thismeans you can buy one power meter and unlock three distinct possibilities by using the same spindle across differentpedalsetups. First released in 2024 with theAssiomaPRO MX SPDandupdated with the PRO RS(Shimano SPD-SL) last year, the PRO portfolio was completed in March 2026with the launch of the PRO RL(Look Keo-compatible version). With three interchangeable pedal bodies now available Shimano SPD, Shimano SPD-SL and Look Keo riders can simply swap Faveros power-reading spindle across different systems. Thateffectively gives you three power metersinone, while also futureproofing themselves against changes in trends, interests or simply what they want from their riding whetherthatson the road or off it. Smart spindle The smart spindle is shared across all three pedal versions. Favero The spindle is at the heart of the FaveroAssiomaPRO range, and not just becauseitsthe onlycomponentshared by all three models. The patented design houses the power meter pedalskeyinnovations, including the rechargeable batteries, electroniccomponentsand strain gauges. This sealed approach protectsall ofthe key components against mud, dust, moisture and general wear and tear,minimisingthe risks ofpowerdropouts mid-ride,while also prolonging the life of the power meterin thelong-term. Combined with Active Temperature Compensation, the spindles design ensures consistency, ride after ride, and 1% accuracy. And that is, ultimately, whatyou need for a power meter reliable, uninterrupted data, so you can focus onhitting the power numbers needed in training,withspike- and interference-free readings toanalyseafter your ride. Proprietary power system Favero says its innovative approach results in accuracy of 1%, regardless of conditions or riding style. Favero The FaveroAssiomaPRO rangedoesntsimply broadcast the strain gauges reading. Instead, it uses an internal gyroscope also positioned within thespindle, andcombines the readings as part ofFaverosInstant Angular Velocity (IAV) Power System. While measuring force and angular velocityarentnovel, Faveros approachis. Some power meters use an average of the angular velocity in their calculations, but this assumes that each pedal stroke is perfectly smooth and uniform an approach that Favero found can lead to errors in actual power output accuracy of up to 4.5%. Instead, by using the instantaneous angular velocity measured by its three-axis gyroscope, Favero is able to claim accuracy of 1%, whatever the conditions or riding style from the irregular pedal strokes typical when tackling steep slopes, through to riding on a turbo trainer. Industry-beating battery All ofthe above would count for nothing if itwasntalso backed by a battery that can go the distance, and theAssiomaPROs rechargeable Lithium-ion batterypacks 160 hours of riding into each full charge the longest life on the market. Ifyoureshort on time and onlyrealisethat your battery level is low asyoureabout to head outofthe doorfor a ride, a 15-minute blast will provide up to 15 hours of use. Whatsmore, charging is as simple as clipping the dual-headed magnetic USB-C cables onto the ports on the spindle, enabling you to charge both pedals simultaneously without removing them from the crank arms. Modular mastery The stainless-steel spindles smart featuresdontend at its internals,because itforms part ofthemodular system that is compatible with three different pedal bodies. TheAssiomaPRO RL is the Look-KEO compatible setup in therange, andfeatures adjustable release tension andthe KEOssignaturesnapwhen clipping in.Each pedal weighs a claimed 130g. The PRO RS,meanwhile,is another road-focused offering, albeit aimed at those who preferShimanosSPD-SLsystem.Itsalso the lightest road power meter pedal on the market. Finally, the PRO MX SPD adds an off-road capability to the equation and is designed for disciplines such as cross-country mountainbiking, gravel and cyclocross. Advanced metrics Favero's Assioma PRO range provides riders with a whole range of performance metrics. Favero Beyond overall power, the FaveroAssiomaPRO rangeopens upa whole host of other metrics to drill into, target and refine. The L/R Power Balance enables you tomonitorthe dominant/non-dominant leg ratio andobservehow this varies in relation to different racing and fitness conditions. This can be particularly useful to work on your imbalances, also in post-traumatic rehabilitationprogrammes. Torque effectiveness highlights how much of the power generated during the pedal stroke contributesto the propulsion of theriderthe higher, the better while pedal smoothness shows how evenly power is distributed throughout the whole pedal stroke. In addition to these standard metrics, Favero also hasa number ofproprietary metrics that are captured as part of its IAV Cycling Dynamics. PCO (Platform Center Offset) shows where force is applied relative to thecentreof the pedal platform, enabling you to fine-tune your positioning and prevent injuries; Power Phase documents where the power is produced during a single pedal stroke; while Rider Positionshows when you were seated or standing during aride, andcan be combined with a course profile to see how your position impacted performance.
