The \u003cstrong\u003eWolf Tooth Premium IS Headset\u003c\/strong\u003e is built for riders who notice every detail—whether you’re dialing in a road, gravel, or mountain bike.\n\u003c\/p\u003e\n\n\u003cp\u003e\nMachined in Minnesota from aircraft-grade \u003cstrong\u003e6061 aluminum\u003c\/strong\u003e, these integrated (IS) headsets are designed for modern frames with molded-in bearing seats (\u003cstrong\u003e41 mm upper \/ 52 mm lower outer bearing diameter\u003c\/strong\u003e). The result is a low-stack, clean look with the kind of precision and durability you expect from Wolf Tooth.\n\u003c\/p\u003e\n\n\u003cp\u003e\nInside, you get \u003cstrong\u003eEnduro stainless steel sealed bearings\u003c\/strong\u003e with a lifetime warranty, backed up by Wolf Tooth’s multi-layer sealing system. An O-ring around the steerer, a custom-molded upper lip seal, and a dual-lip seal on the crown race all work together to keep water, grit, and winter road salt away from the bearings. In real riding, that means less creaking, less play, and more seasons of smooth steering.\n\u003c\/p\u003e\n\n\u003cp\u003e\nUppers and lowers are sold separately so you can match exactly what your frame needs. The \u003cstrong\u003eupper assembly\u003c\/strong\u003e includes Wolf Tooth’s Ultralight Stem Cap with Integrated Spacer, plus an aluminum bolt and star nut (for steel or alloy steerers). Top covers are available in \u003cstrong\u003e7 mm, 15 mm, and 25 mm\u003c\/strong\u003e options so you can fine-tune your stack height without stacking a tower of spacers. For forks with carbon steerer tubes, you’ll use a \u003cstrong\u003ecompression plug\u003c\/strong\u003e instead of the star nut.\n\u003c\/p\u003e\n\n\u003cp\u003e\nThe \u003cstrong\u003eIS lower headset\u003c\/strong\u003e is kept intentionally minimal: just the bearing and a black-anodized crown race that disappears once installed. The over-molded dual-lip seal on the crown race protects the lower bearing in harsh conditions—perfect for all-weather commuting, muddy cyclocross, or long gravel days.\n\u003c\/p\u003e\n\n\u003cp\u003e\nEvery headset component is precision-machined in-house at Wolf Tooth to tight tolerances, then finished in a range of anodized colors so you can either keep it stealth or add a small hit of color at the front of the bike.\n\u003c\/p\u003e\n\n\u003ch2\u003eKey Details\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eFor frames using IS (Integrated Standard) headsets with \u003cstrong\u003e41 mm upper \/ 52 mm lower outer bearing diameter\u003c\/strong\u003e\n\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnduro stainless steel sealed bearings\u003c\/strong\u003e (upper and lower) with lifetime bearing warranty\u003c\/li\u003e\n  \u003cli\u003eUppers and lowers sold separately\u003c\/li\u003e\n  \u003cli\u003eTop cover options: 7 mm (8 mm total stack), 15 mm (15 mm total stack), 25 mm (25 mm total stack)\u003c\/li\u003e\n  \u003cli\u003eBevel angle: \u003cstrong\u003e36° x 45°\u003c\/strong\u003e\n\u003c\/li\u003e\n  \u003cli\u003eMaterial: \u003cstrong\u003e6061 aluminum\u003c\/strong\u003e\n\u003c\/li\u003e\n  \u003cli\u003eWeight: 52 g (7 mm), 59 g (15 mm), 66 g (25 mm)\u003c\/li\u003e\n  \u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eImportant Notes\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIS42 is not compatible\u003c\/strong\u003e with Specialized mountain bikes or frames using the Campagnolo Hiddenset standard\u003c\/li\u003e\n  \u003cli\u003eSupplied star nut is for \u003cstrong\u003esteel or aluminum steerers only\u003c\/strong\u003e – use a compression plug on carbon steerers\u003c\/li\u003e\n  \u003cli\u003eStem cap bolt torque: \u003cstrong\u003e2–3 Nm\u003c\/strong\u003e with light grease on the threads only\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\nPair your Premium IS headset with \u003cstrong\u003eWolf Tooth precision headset spacers\u003c\/strong\u003e and the \u003cstrong\u003eWolf Tooth crown race installation adapter\u003c\/strong\u003e for an easier, cleaner build that will stay quiet and precise for years.\n\u003c\/p\u003e\n","brand":"Wolf Tooth","offers":[{"title":"Upper \/ IS41\/28.6 7mm Stack \/ Black","offer_id":45079752867884,"sku":"IS41U-5MM-BLK","price":64.95,"currency_code":"USD","in_stock":true},{"title":"Upper \/ IS41\/28.6 7mm Stack \/ Red","offer_id":45079752900652,"sku":"IS41U-5MM-RED","price":64.95,"currency_code":"USD","in_stock":true},{"title":"Upper \/ IS41\/28.6 7mm Stack \/ Blue","offer_id":45079752933420,"sku":"IS41U-5MM-BLU","price":64.95,"currency_code":"USD","in_stock":true},{"title":"Upper \/ IS41\/28.6 7mm Stack \/ Orange","offer_id":45079752966188,"sku":"IS41U-5MM-ORG","price":64.95,"currency_code":"USD","in_stock":true},{"title":"Upper \/ IS41\/28.6 7mm Stack \/ Gold","offer_id":45079752998956,"sku":"IS41U-5MM-GLD","price":64.95,"currency_code":"USD","in_stock":false},{"title":"Upper \/ IS41\/28.6 7mm Stack \/ Raw Silver","offer_id":45079753064492,"sku":"IS41U-5MM-RSIL","price":64.95,"currency_code":"USD","in_stock":false},{"title":"Upper \/ IS41\/28.6 7mm Stack \/ Ultraviolet Purple","offer_id":45079753097260,"sku":"IS41U-5MM-PRU","price":64.95,"currency_code":"USD","in_stock":true},{"title":"Upper \/ IS42\/28.6 7mm Stack \/ Black","offer_id":45079753392172,"sku":"IS42U-5MM-BLK","price":64.95,"currency_code":"USD","in_stock":true},{"title":"Upper \/ IS42\/28.6 7mm Stack \/ Red","offer_id":45079753424940,"sku":"IS42U-5MM-RED","price":64.95,"currency_code":"USD","in_stock":true},{"title":"Upper \/ IS42\/28.6 7mm Stack \/ Blue","offer_id":45079753457708,"sku":"IS42U-5MM-BLU","price":64.95,"currency_code":"USD","in_stock":false},{"title":"Upper \/ IS42\/28.6 7mm Stack \/ Orange","offer_id":45079753490476,"sku":"IS42U-5MM-ORG","price":64.95,"currency_code":"USD","in_stock":true},{"title":"Upper \/ IS42\/28.6 7mm Stack \/ Gold","offer_id":45079753523244,"sku":"IS42U-5MM-GLD","price":64.95,"currency_code":"USD","in_stock":true},{"title":"Upper \/ IS42\/28.6 7mm Stack \/ Raw Silver","offer_id":45079753556012,"sku":"IS42U-5MM-RSIL","price":64.95,"currency_code":"USD","in_stock":true},{"title":"Upper \/ IS42\/28.6 7mm Stack \/ Ultraviolet Purple","offer_id":45079753588780,"sku":"IS42U-5MM-PRU","price":64.95,"currency_code":"USD","in_stock":true},{"title":"Lower \/ IS52\/40 \/ Black","offer_id":45110127657004,"sku":"IS52L-40","price":44.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/wolf-tooth-premium-is-headsets-integrated-standard-8682097.jpg?v=1771292067","url":"https:\/\/ricycles.com\/es\/products\/wolf-tooth-premium-is-headsets-integrated-standard","provider":"RA Cycles","version":"1.0","type":"link"}
