{"product_id":"avian-versus-carbon-bmx-race-fork-stealth-black-evo","title":"Avian Versus Carbon BMX Race Fork - Stealth Black Evo","description":"\u003cp\u003eThe Avian Versus Carbon BMX Fork is our flagship race fork. It's the fork our factory-supported riders run at the UCI World Cup, and it covers every BMX class in one product family — Youth 20x1\", Youth Cruiser 24\", Pro 20x1-1\/8\", Pro Tapered 20\", and Cruiser Tapered 24\". Six configurations, one design standard.\u003c\/p\u003e\n\n\u003cp\u003eThe thing we're most proud of isn't the Toray carbon fiber legs (though they're excellent). It's the integrated internal locking system. Every other carbon fork on the market uses either a star nut pressed into the steerer — which concentrates crushing force on a thin carbon tube wall — or an aftermarket expander plug that adds weight and a failure point. Ours uses an M10 aluminum bolt that threads directly into the steerer. You install it with a 5mm Allen key, it preloads the headset and locks your stem, and nothing touches the outside of your steerer tube. Simpler, lighter, and structurally cleaner than either alternative.\u003c\/p\u003e\n\n\u003cp\u003eYouth versions use a full carbon steerer for minimum weight. Pro and Tapered versions use a 4mm thick 7005 aluminum steerer — stiffer under adult-class sprint loads and more forgiving of stem overtightening. Torque the locking bolt to 4–5 Nm. Maximum is 5.5 Nm. Exceed that and you strip the threads in the steerer — there's no repair for that.\u003c\/p\u003e\n\n\u003ch3\u003eConfigurations Available\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eVersion\u003c\/th\u003e\n\u003cth\u003eSteerer\u003c\/th\u003e\n\u003cth\u003eDropout\u003c\/th\u003e\n\u003cth\u003eWheel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eYouth\u003c\/td\u003e\n\u003ctd\u003eCarbon 20x1\"\u003c\/td\u003e\n\u003ctd\u003e10mm\u003c\/td\u003e\n\u003ctd\u003e20\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eYouth Cruiser\u003c\/td\u003e\n\u003ctd\u003eCarbon 24\"x1-1\/8\"\u003c\/td\u003e\n\u003ctd\u003e10mm\u003c\/td\u003e\n\u003ctd\u003e24\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePro\u003c\/td\u003e\n\u003ctd\u003e7005 alloy 20x1-1\/8\"\u003c\/td\u003e\n\u003ctd\u003e10mm or 20mm\u003c\/td\u003e\n\u003ctd\u003e20\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePro Tapered\u003c\/td\u003e\n\u003ctd\u003e7005 alloy 20\"x1-1\/8\"–1.5\"\u003c\/td\u003e\n\u003ctd\u003e20mm\u003c\/td\u003e\n\u003ctd\u003e20\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCruiser Tapered\u003c\/td\u003e\n\u003ctd\u003e7005 alloy 24\"x1-1\/8\"–1.5\"\u003c\/td\u003e\n\u003ctd\u003e20mm\u003c\/td\u003e\n\u003ctd\u003e24\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003cp\u003e\u003cstrong\u003eLocking bolt torque:\u003c\/strong\u003e 4–5 Nm recommended | 5.5 Nm maximum\u003cbr\u003e\n\u003cstrong\u003eStem clamp torque:\u003c\/strong\u003e Carbon steerer: 4–5 Nm | Alloy steerer: 10–12 Nm\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eSelect your configuration from the dropdown.
