If you are looking for a simple and accurate solution to measure your power during your mountain biking or gravel riding sessions, Look X-Track Power pedals are the perfect choice. As easy to install as conventional pedals, you can easily transfer them from one bike to another. You can even consider using them on your road bike thanks to their large 550 mm² contact surface, which is slightly larger than the Look Keo 2 max pedals! The accuracy of these dual-sensor pedals is their second advantage. With a constant of +/- 1% and analysis of several pedalling dynamics such as power, cadence, fluidity, efficiency and right/left leg balance, you'll have everything you need to optimise your performance!In terms of battery life, you can complete numerous sessions without worrying about the battery status, with a battery life of up to 60 hours. What's more, these pedals offer the advantage of being easily rechargeable via a USB-C cable, so you no longer have to worry about having a spare battery.Another advantage is that all the parts that make up the pedals are sold separately, making them 95% repairable. Finally, the last advantage of these pedals is theircompatibility with the most popular cleats on the market, Shimano SPD, which are undeniably robust and durable.
