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.
The ES PMTT is one of the few power meters specially designed for using with track bikes and other single speed bikes. Ridea track chainrings range from 44t to a whooping 67t size to challenge the strongest legs in the world.
