Power measurement lives inside the DUB spindle itself, reading left-side output and doubling it to calculate total wattage, all while adding less than 40 grams over a standard crankset.\u003c\/p\u003e\n\n\u003cp\u003eA single AAA lithium battery powers the system for over 400 hours — enough for a full season of training and racing before you need to think about a swap. The unit carries an IPX7 waterproof rating, meaning it's built to handle rain, puddles, and pressure washing without complaint. It works with any standard DUB bottom bracket, so if your bike is already running that interface, installation is straightforward.\u003c\/p\u003e\n\n\u003ch3\u003eSRAM Rival AXS E1 DUB Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement method:\u003c\/strong\u003e Left-side spindle-based power, doubled to estimate total output\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight penalty:\u003c\/strong\u003e Less than 40g over a standard crankarm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery:\u003c\/strong\u003e Single AAA lithium — rated for 400+ hours\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWater resistance:\u003c\/strong\u003e IPX7 rated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBottom bracket compatibility:\u003c\/strong\u003e DUB standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrank lengths available:\u003c\/strong\u003e 160mm, 165mm, 170mm, 172.5mm, 175mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"SRAM","offers":[{"title":"160mm","offer_id":44469507096620,"sku":"00.3018.403.000","price":195.0,"currency_code":"USD","in_stock":true},{"title":"165mm","offer_id":44469507129388,"sku":"00.3018.403.001","price":195.0,"currency_code":"USD","in_stock":true},{"title":"170mm","offer_id":44469507162156,"sku":"00.3018.403.003","price":195.0,"currency_code":"USD","in_stock":true},{"title":"172.5mm","offer_id":44469507194924,"sku":"00.3018.403.004","price":195.0,"currency_code":"USD","in_stock":true},{"title":"175mm","offer_id":44489420963884,"sku":"00.3018.403.005","price":195.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/sram-rival-axs-e1-dub-power-meter-crankarm-upgrade-5963602.jpg?v=1771293190","url":"https:\/\/ricycles.com\/products\/sram-rival-axs-e1-dub-power-meter-crankarm-upgrade","provider":"RA Cycles","version":"1.0","type":"link"}
