{"product_id":"fulcrum-xdr-alloy-freehub-body","title":"Fulcrum XDR Alloy Freehub Body For Racing\/Wind\/Airbeat DB Wheels","description":"\u003cp style=\"text-align:center;font-style:italic;font-size:18px;border:1px solid #ddd;background:#f7f7f7;padding:16px;\"\u003eA direct replacement XDR freehub body for the rider who has already made the jump to SRAM 11- or 12-speed road and gravel drivetrains, with enough precise, conical-bearing-matched engagement to keep an existing Fulcrum wheelset running exactly as it did on day one.\u003c\/p\u003e\n\u003ch5\u003eOverview\u003c\/h5\u003e\n\u003cp\u003eShimano\/SRAM freehub drivers wear out long before the hub shell or bearings do - the aluminium splines that the cassette sprockets bite into eventually get chewed up, and that is exactly the part this body replaces. Fulcrum builds this XDR freehub body specifically for its own conical-bearing hub platform, so it drops onto the existing axle and bearing system without needing a full hub rebuild.\u003c\/p\u003e\n\u003cp\u003eIt is machined from aluminium and uses a three-pawl engagement mechanism matched to the SRAM XDR spline standard, which is what SRAM's 11- and 12-speed XPLR and Eagle\/Red road and gravel cassettes key onto. Fulcrum includes the 1.8mm spacer ring needed if a rider ever wants to run an XD (not XDR) cassette on this XDR-spec body, which is a small but genuinely useful inclusion rather than an extra part to track down separately.\u003c\/p\u003e\n\u003cp\u003eIn the real world this is a wear-item swap: it makes sense for a rider whose cassette has started skipping or whose pawls have gone soft on a Fulcrum Wind 75\/750 DB, Airbeat 400\/500 DB, Racing 4\/5\/6 DA, Racing 800\/900 DB, or Rapid Red Carbon 3\/300\/900 wheel, rather than for anyone building a wheel from scratch.\u003c\/p\u003e\n\u003ch5\u003eWhy You'll Like It\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eDrop-in fit on your existing hub.\u003c\/strong\u003e Because it is built for Fulcrum's own conical-bearing hub architecture, there is no need to replace bearings, the axle, or the hub shell - just the worn driver.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSRAM XDR spline, with XD covered too.\u003c\/strong\u003e The driver is cut to the SRAM XDR standard used on current 11\/12-speed road and gravel groupsets, and the included 1.8mm spacer lets it accept XD-spec cassettes as well.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThree-pawl engagement.\u003c\/strong\u003e A three-pawl design gives reliable, even engagement under power, which matters when a rider is out of the saddle sprinting or grinding up a loose gravel climb.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGenuine Fulcrum part.\u003c\/strong\u003e Sourcing the exact branded replacement avoids the fitment and durability gamble of a generic freehub body on a precision Fulcrum hub.\u003c\/p\u003e\n\u003ch5\u003eWho Is It For?\u003c\/h5\u003e\n\u003cp\u003eThis is for an existing Fulcrum wheel owner - someone running a Wind, Airbeat, Racing DA\/DB, or Rapid Red Carbon wheelset - who has moved their drivetrain to SRAM 11- or 12-speed road or 1x gravel\/XPLR and needs the correct driver to make the cassette seat properly, or whose current freehub body is worn, skipping, or making noise under load.\u003c\/p\u003e\n\u003cp\u003eIt also suits riders in India doing their own seasonal drivetrain maintenance ahead of the winter riding season, where dust and grit on gravel routes around cities like Pune and Bangalore accelerate pawl wear faster than on a purely tarmac bike.\u003c\/p\u003e\n\u003ch5\u003eGood to Know\u003c\/h5\u003e\n\u003cp\u003eInstallation is a standard home-mechanic job with the usual cassette lockring tool and a hub axle wrench - no special press tools are needed since the body simply slides onto the existing axle splines and freehub mechanism.\u003c\/p\u003e\n\u003cp\u003eA light coat of a freehub-safe grease on the driver splines before refitting the cassette makes future cassette removal easier and helps keep the pawls running smoothly.\u003c\/p\u003e\n\u003cp\u003eBecause the spacer ring for XD cassette compatibility ships with the part, there is no need to separately source it if switching cassette standards down the line.\u003c\/p\u003e\n\u003ch5\u003eTechnical Specifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFreehub Type:\u003c\/strong\u003e SRAM XDR (3-pawl), XD-compatible with included 1.8mm spacer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeed:\u003c\/strong\u003e 11-speed and 12-speed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fulcrum Wind 75\/750 DB, Airbeat 400\/500 DB, Racing 4\/5\/6 DA (2022+), Racing 900 DB (2021+), Racing 800 DB, Rapid Red Carbon 3\/300\/900 (conical bearing hubs)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Not published by Fulcrum\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eAdditional Information\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e China\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImported By:\u003c\/strong\u003e We Snap India, M.
