{"product_id":"zeb-ult-b1-csu","title":"RockShox ZEB Ult B1 CSU","description":"\u003cp\u003eThe crown steerer upper assembly is the structural core of a RockShox ZEB Ultimate B1+ fork from the 2027 model year onward. It combines the steerer tube, the crown and both upper tubes as a single assembly, and it is replaced as one part after a crash or once creaking shows that the crown to upper tube joint has moved.\u003c\/p\u003e\n\u003cp\u003eThis assembly uses the ButterWagon Tech uppers that RockShox lists for the LinearXL generation of the ZEB Ultimate. The steerer is a 1.5 inch tapered aluminum unit, and the crown accepts both 27.5 and 29 inch lower leg assemblies, so wheel size follows the lowers. Fork offset is fixed by this part and cannot be altered afterwards.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQuick Facts\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%; border-collapse: collapse; border: 1px solid #ddd;\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color: #F2F2F2; text-align: left;\"\u003e\n      \u003cth style=\"padding: 12px; border: 1px solid #ddd;\"\u003eFeature\u003c\/th\u003e\n      \u003cth style=\"padding: 12px; border: 1px solid #ddd;\"\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003eRockShox ZEB Ultimate B1+ (2027 and later)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003e\u003cstrong\u003eFork Offset\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003e38 mm or 44 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003e\u003cstrong\u003eSteerer\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003e1.5 inch tapered\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003e\u003cstrong\u003eWheel Size\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003e27.5 inch and 29 inch\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #ddd;\"\u003eAluminum\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"RockShox","offers":[{"title":"44mm offset","offer_id":43080606679103,"sku":"943295-01","price":558.0,"currency_code":"CAD","in_stock":false},{"title":"38mm offset","offer_id":43080606711871,"sku":"943295-02","price":558.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0066\/2283\/8853\/files\/rockshox-zeb-ult-b1-csu-parts-suspension-service-parts-1259828071.png?v=1790219608","url":"https:\/\/bici.cc\/products\/zeb-ult-b1-csu","provider":"Bici","version":"1.0","type":"link"}
