Ridea SPM2 is a family of spider-based power meters available for both road, track/single speed and soon available for MTB too. The spider is the best place to integrate a power meter because it is where you can get the most precise measurements with the less added weight (65 g more than a regular spider).
Ridea SPM2 integrates four measuring gauges to deliver accurate data (±1.5%) for both legs during up to 120 hours with an integrated battery rechargeable via USB. Everything protected under an IPX6 certification.
Connect via ANT+™ or Bluetooth® LE to your cycling computer or smartphone app and just ride! The automatic zero offset function will provide precise measurements of all your trainings and races.
