{"product_id":"duke-sierra-mm3-xdr-wheelset","title":"Duke Sierra MM3 XDR Wheelset","description":"\u003cp\u003eDuke's aero gravel wheel, built on their own MadMax3 hubs with a SRAM XDR driver. The front rim is a wide Sierra Æra profile that blends cleanly into a 40 to 45mm tire, and the rear runs a deeper, narrower Æra profile. You get real aero gains on fast gravel without the wheel feeling twitchy when the wind picks up.\u003c\/p\u003e\u003cp\u003eTwo builds are in stock. The 56\/48W (W48 front, 56 rear) is the fast one, for race days and flatter, faster courses. The 48\/42W (W42 front, 48 rear) is a little lighter and more of an all-rounder for mixed terrain and longer climbs. Both use hooked, tubeless-ready Toray T1100 carbon rims with a 28mm internal width, hand-built by Duke.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eIn stock: 56\/48W (W48 front, 56 rear) and 48\/42W (W42 front, 48 rear)\u003c\/li\u003e\n\u003cli\u003eFront: wide Æra profile, 43mm external, 28mm internal (W48 is 48mm deep, W42 is 42mm deep)\u003c\/li\u003e\n\u003cli\u003eRear: Æra profile, 35.9mm external, 28mm internal (56 or 48mm deep)\u003c\/li\u003e\n\u003cli\u003eRim weights: W48 460g, 56 410g, W42 420g, 48 390g\u003c\/li\u003e\n\u003cli\u003eHooked, tubeless ready, best with 40 to 45mm tires\u003c\/li\u003e\n\u003cli\u003eÆra micro-relief rim surface, which Duke says cuts drag by up to 10% compared with a smooth rim\u003c\/li\u003e\n\u003cli\u003e24-hole rims laced to Duke MadMax3 CL SP hubs: conical double-ratchet freehub, Center Lock rotors\u003c\/li\u003e\n\u003cli\u003eSRAM XDR driver\u003c\/li\u003e\n\u003cli\u003e130kg max system weight\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Duke","offers":[{"title":"56\/48W","offer_id":44475948236865,"sku":"210000010487","price":3690.0,"currency_code":"USD","in_stock":true},{"title":"48\/42W","offer_id":44475948302401,"sku":"210000010488","price":3690.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/8372\/5377\/files\/wheel-s-duke-sierra-aera-w-48-aera-56-duke-madmax3-cl-sp_db381388-ab4a-4062-82f1-a80b44c34319.jpg?v=1792282362","url":"https:\/\/thebicyclestation.com\/products\/duke-sierra-mm3-xdr-wheelset","provider":"The Bicycle Station","version":"1.0","type":"link"}
