The racing proved SPM2 power meter spider arrives to the latest Ridea cranks keeping all the functions present in the ES and IT series of cranks, plus the improved arm-spider connection of Pneuma cranks.
Ridea SPM2 is a family of spider-based power meters available for road, track/single speed and mountain bikes. A spider-based power meter combines the ability to provide the most precise measurements in both legs with the smallest weight penalty (65 g more on average 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.
