This system takes into account a combination of frame and fork dimensions. Both the top and bottom parts of the headset are marked by two alphanumeric identifiers. The first identifier indicates the type of headset (External Cup, Zero Stack, Integrated) and head tube diameter. The second identifier - separated from the first by a backslash - indicates the diameter of the steerer tube. When referring to a complete headset, the specifications of both top and bottom parts must be combined.\n\nNomenclature:\nEC: Bearings contained within headset cups that are located outside of the frame (External Cup)\nZS: Bearings contained within pressed-in headset cups where the cup and bearings rest inside the frame (Zero Stack)\nIS: Bearings that fit directly into a bonded or machined interface that is integrated into the frame (Integrated)\n\nManufacturer Numbers:\nIS42\/28.6 (8.3 mm): 33035337004\nIS42\/28.6 (15.3 mm): 33035337005\n\nContents:\n1 x Ritchey Comp cartridge drop-in bearing\n1 x bearing cover\n1 x top cap with bolt and star nut\n\nWeight:\nblack | 1 1\/8\" | IS42\/28,6 (15,3 mm): 44 g\nblack | 1 1\/8\" | IS42\/28,6 (8,3 mm): 35 g\n\nManufacturer: Ritchey Design Inc. 575 Old County Road San Carlos CA 94070 USA info@ritcheylogic.com\nDistributor: Cosmic Sports GmbH Leyher Straße 47 90763 Fürth Germany info@cosmicsports.de","brand":"Ritchey","offers":[{"title":"Default Title","offer_id":47171784868159,"sku":"0796941332538","price":56.99,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0841\/3478\/9439\/files\/260dae58e4389924_fb189b3e-5907-43cd-8a2f-f4535cc1b951.jpg?v=1778399595","url":"https:\/\/tormino.com\/products\/ritchey-comp-drop-in-upper-balhoofd-15-3mm-top","provider":"Tormino","version":"1.0","type":"link"}
