Configure it via the Magene app, where you can also update firmware, then pair it with your GPS head unit — calibration can be started from the head unit too. Because it is a spider-based power meter sitting between the crankset and chainring, total power readings are accurate and stable, and cadence is reported so no separate cadence sensor is needed.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy:\u003c\/strong\u003e ±1%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery life:\u003c\/strong\u003e 330+ hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement type:\u003c\/strong\u003e spider-based total power (true, not doubled)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetrics:\u003c\/strong\u003e power, cadence, left\/right balance, pedaling smoothness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBottom bracket compatibility:\u003c\/strong\u003e includes T47 support\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroupset compatibility:\u003c\/strong\u003e Shimano\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetup:\u003c\/strong\u003e Magene app for configuration and firmware updates\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrank lengths:\u003c\/strong\u003e 165 mm, 170 mm, 172.5 mm, 175 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eChainrings not included.\u003c\/em\u003e\u003c\/p\u003e","brand":"Magene","offers":[{"title":"165mm","offer_id":47985406148786,"sku":"MAG-P010634539-165","price":419.99,"currency_code":"CAD","in_stock":true},{"title":"170mm","offer_id":47985406181554,"sku":"MAG-P010634539-170","price":419.99,"currency_code":"CAD","in_stock":true},{"title":"172.5mm","offer_id":47985406214322,"sku":"MAG-P010634539-172-5","price":419.99,"currency_code":"CAD","in_stock":true},{"title":"175mm","offer_id":47985406247090,"sku":"MAG-P010634539-175","price":419.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0289\/6045\/6837\/files\/image_f7cd5989-ac7a-4302-8736-d270f96ca8e8.png?v=1788449554","url":"https:\/\/www.wheelsofbloor.com\/products\/magene-pes-515-power-meter-crank","provider":"Wheels of Bloor","version":"1.0","type":"link"}
