The reliability of these power meter pedals is excellent, and the ease of swapping between bikes makes them an great choice for those with more than a single road bike.
For years, those who wanted power meter pedals had few options other than using Look Keo cleat compatible pedals. Italian manufacturer Favero debuted the Assioma Duo Shi (dual-sided Shimano) power meter some four years after the debut of its Look-compatible version, in 2017.
Unlike the Look compatible version of the power meter, which arrives as complete pedals with power meter spindles and pedal bodies, the Shimano version is sold as power-measuring spindles-only, so you’ll have to bring your own pedal bodies, or make an additional purchase.
