The SRM spider sits between the chainrings and the arms, built around the 145\/112mm bolt circle diameter of modern Campagnolo chainrings, so the integration is seamless and the ride feel stays true to what Campagnolo riders expect.\u003c\/p\u003e\n\u003cp\u003eThe spider measures power via strain gauges to \u003cstrong\u003e±1% accuracy\u003c\/strong\u003e, transmits via ANT+ — broadcasting cadence alongside power — and runs for approximately 100 hours on a single charge through its built-in rechargeable battery. Temperature compensation is handled automatically, an important feature for crank-based meters where offset can drift as conditions change. The unit is fully sealed, so rain, mud, and post-ride cleaning with a pressure washer won't affect it. Available in 172.5mm crank arm length with 52x36 or 53x39 chainring combinations.\u003c\/p\u003e\n\u003ch3\u003eSRM Campagnolo Rechargeable Powermeter Crankset Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n\u003cli\u003eAccuracy: ±1%\u003c\/li\u003e\n\u003cli\u003eTransmission: ANT+ (power and cadence)\u003c\/li\u003e\n\u003cli\u003eBattery: Built-in rechargeable, ~100-hour runtime per charge\u003c\/li\u003e\n\u003cli\u003eChainring compatibility: 145\/112mm BCD (Campagnolo standard)\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SRM","offers":[{"title":"172.5mm \/ 52x36","offer_id":43521186332716,"sku":"PM-SRM-RECH-CAM-4-BOLT-36-172","price":1599.99,"currency_code":"USD","in_stock":true},{"title":"172.5mm \/ 53x39","offer_id":43521186365484,"sku":"PM-SRM-RECH-CAM-4-BOLT-39-172","price":1599.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/srm-campagnolo-rechargeable-powermeter-crankset-6582673.jpg?v=1771296550","url":"https:\/\/ricycles.com\/products\/srm-campagnolo-rechargeable-powermeter-crankset","provider":"RA Cycles","version":"1.0","type":"link"}
