{"product_id":"quarq-dzero-gxp-aluminum-crank","title":"Quarq DZero GXP Aluminum Crank","description":"\u003cp\u003eThe \u003cstrong\u003eQuarq DZero GXP Aluminum Crank\u003c\/strong\u003e is built around the same DZero spider found on Quarq's higher-tier cranksets, paired with forged aluminum arms — a practical choice for riders who want accurate, reliable power data without the weight penalty being a priority. That spider is the core of the system, and it does the heavy lifting: measuring your output consistently, broadcasting simultaneously over ANT+ and Bluetooth Low Energy, and doing all of it without requiring a magnet on the frame to wake it up.\u003c\/p\u003e\n\u003cp\u003eAccuracy sits at ±1.5%, and the system includes temperature compensation across a 10,000-degree range to keep readings consistent as conditions change through a ride. OmniCal means you won't need to recalibrate when swapping chainrings — a genuine convenience for riders who run multiple setups. The user-replaceable CR2032 coin cell battery is easy to source, and an IPX7 waterproof rating means the unit handles rain without complaint. A color-coded LED gives you real-time feedback on battery status and zero calibration. Firmware updates are handled wirelessly through the Qalvin app.\u003c\/p\u003e\n\u003ch3\u003eQuarq DZero GXP Aluminum Crank Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eBCD:\u003c\/strong\u003e 130mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle interface:\u003c\/strong\u003e GXP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy:\u003c\/strong\u003e ±1.5%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWireless:\u003c\/strong\u003e ANT+ and Bluetooth Low Energy (simultaneous broadcast)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery:\u003c\/strong\u003e CR2032, user-replaceable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWaterproof rating:\u003c\/strong\u003e IPX7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Quarq","offers":[{"title":"175mm \/ 130bcd","offer_id":43595072733228,"sku":"00.3018.154.175","price":399.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/quarq-dzero-gxp-aluminum-crank-4664674.jpg?v=1771294455","url":"https:\/\/ricycles.com\/products\/quarq-dzero-gxp-aluminum-crank","provider":"RA Cycles","version":"1.0","type":"link"}
