The hidden fifth-arm spider design integrates directly with Red chainrings, so the drivetrain behaves exactly as it would without a power meter in the system.\u003c\/p\u003e\n\u003cp\u003eThe DZero spider transmits both ANT+ and Bluetooth Low Energy signals simultaneously, meaning your head unit and phone can pull data at the same time — useful for logging rides without carrying a dedicated computer. A multicolor LED provides at-a-glance feedback on battery status and zero calibration, replacing the single indicator of earlier generations. Battery life is rated at 200 hours from a standard user-replaceable CR2032 coin cell, and firmware updates are handled wirelessly through the Qalvin app at no cost.\u003c\/p\u003e\n\u003ch3\u003eSRAM Red DZero BB30 Crank Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eBottom Bracket Interface:\u003c\/strong\u003e BB30\u003cstrong\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal:\u003c\/strong\u003e ANT+ and Bluetooth Low Energy (dual simultaneous transmission)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery:\u003c\/strong\u003e CR2032 coin cell, user-replaceable, rated to 200 hours\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"SRAM","offers":[{"title":"177.5mm \/ 130bcd","offer_id":43594847780908,"sku":"00.3018.133.177","price":549.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/sram-red-dzero-bb30-crank-6188814.jpg?v=1771294508","url":"https:\/\/ricycles.com\/products\/sram-red-dzero-bb30-crank","provider":"RA Cycles","version":"1.0","type":"link"}
