{"product_id":"kfx-boost-29-wheelset","title":"FSA KFX Boost 29\" Wheelset","description":"\u003cp\u003eThe KFX Boost 29\" is FSA's in-house-built carbon mountain bike wheelset, notable because FSA makes the carbon itself rather than sourcing rims from a third party, and hand-assembles every wheel. It's built on Boost hub spacing for modern trail and enduro forks and frames.\u003c\/p\u003e\u003cp\u003eThe rim uses a variable-height, asymmetric, hookless design at 22-24mm depth, 33mm width, and 28mm internal width, giving it a wide tubeless-compatible platform for current trail tire widths. FSA's alloy PRS hub uses a 72-tooth ratchet system, matching the fast engagement found on the brand's road and gravel wheels, and it's compatible with both MicroSpline and XD freehub standards.\u003c\/p\u003e\u003ch4\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTrail and enduro riders on 29-inch Boost-spaced bikes who want an in-house-built carbon wheelset\u003c\/li\u003e\n\u003cli\u003eRiders who want fast hub engagement (72-tooth ratchet) for technical, punchy trail sections\u003c\/li\u003e\n\u003cli\u003eNot built for non-Boost frames — confirm your hub spacing before ordering\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003e\u003cstrong\u003eWhat to Look For\u003c\/strong\u003e\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHub spacing: TA-12 front and rear end caps, built specifically for Boost-spaced frames and forks\u003c\/li\u003e\n\u003cli\u003eFreehub standard: compatible with MicroSpline and XD — confirm which matches your cassette\u003c\/li\u003e\n\u003cli\u003eRotor mount: ISO 6-bolt, so check compatibility with your existing rotors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eRim:\u003c\/strong\u003e A variable-height (22-24mm depth), asymmetric, hookless carbon rim at 33mm width and 28mm internal width is built entirely in-house by FSA, including the carbon production itself.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHub:\u003c\/strong\u003e An alloy PRS hub with a 72-tooth ratchet system gives fast, precise engagement, useful when power needs to go down instantly on technical trail terrain.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBearings and spokes:\u003c\/strong\u003e Seven sealed cartridge bearings (2 front, 5 rear) and 2-cross double-butted spokes with brass nipples balance strength and weight.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFreehub compatibility:\u003c\/strong\u003e MicroSpline and XD compatibility covers the two dominant modern drivetrain standards, rather than locking riders into one.\u003c\/p\u003e\u003ch4\u003e\u003cstrong\u003eRider Intent Summary\u003c\/strong\u003e\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBiggest strengths: in-house carbon production and hand assembly, plus a fast 72-tooth ratchet hub\u003c\/li\u003e\n\u003cli\u003eTradeoffs: Boost spacing and TA-12 end caps only, so it won't fit older or non-Boost frames\u003c\/li\u003e\n\u003cli\u003eWhat makes it different: FSA's vertical integration — building its own carbon rather than sourcing it — is uncommon among wheel brands at this price\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003e\u003cstrong\u003eVictory's Take\u003c\/strong\u003e\u003c\/h4\u003e\u003cp\u003eWe recommend the KFX Boost 29\" through Victory Bicycle Studio to trail and enduro riders on Boost-spaced bikes who want a wheelset built and finished entirely under one roof.\u003c\/p\u003e","brand":"FSA","offers":[{"title":"29\" Rear Wheel - MS12","offer_id":53552455713075,"sku":"720-0094184031","price":1061.0,"currency_code":"USD","in_stock":true},{"title":"29\" Rear Wheel XD","offer_id":53552455745843,"sku":"720-0094188031","price":1061.0,"currency_code":"USD","in_stock":true},{"title":"29\" Front Wheel","offer_id":53552455778611,"sku":"720-0094183031","price":749.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0981\/3685\/0739\/files\/media_afc03b0a-3a33-4243-988a-2942fd373077.jpg?v=1782440695","url":"https:\/\/victorybicyclestudio.com\/products\/kfx-boost-29-wheelset","provider":"Victory Bicycle Studio","version":"1.0","type":"link"}
