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. Nomenclature:EC:Bearings contained within headset cups that are located outside of the frame (External Cup)ZS:Bearings contained within pressed-in headset cups where the cup and bearings rest inside the frame (Zero Stack)IS:Bearings that fit directly into a bonded or machined interface that is integrated into the frame (Integrated)tpi threads per inch Models:IS42/28.6 Design: integrated (IS)Application: topSteerer Tube: 28.6 mmHead Tube (Frame Inner Diameter): 42 mm IS52/40 Design: integrated (IS)Application: bottomSteerer Tube Crown Race: 40 mmHead Tube (Frame Inner Diameter): 52 mmManufacturer Number:BAA0783K Contents:1 x Cane Creek top dust cap1 x Cane Creek compression ring1 x Cane Creek crown race1 x Cane Creek top cap1 x Cane Creek star nut1 x Cane Creek hex boltincl. incl. stainless steel bearings Manufacturer: Cane Creek Cycling Components 355 Cane Creek Rd Fletcher NC 28732 USA info@canecreek.com Distributor: Cosmic Sports GmbH Leyher Straße 47 90763 Fürth Germany info@cosmicsports.de
