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)Models:IS42/28.6 Design: integrated (IS)Application: topSteerer Tube: 28.6 mmHead Tube (Frame Inner Diameter): 42 mmStack Height: 9 mm IS52/40 Design: integrated (IS)Application: bottomSteerer Tube Crown Race: 40 mmHead Tube (Frame Inner Diameter): 52 mmStack Height: 1 mmContents:1 x KCNC top cartridge bearing1 x KCNC bottom cartridge bearing1 x KCNC headset cap1 x KCNC top cap1 x star nut with bolt1 x crown race Manufacturer: KCNC International No. 5 Alley 1 Lane 123 Section 6 Mingzhong Rd Taichung Taiwan info@kcnc.com.tw Distributor: COOOLsport HandelsgmbH Feistritz 29 8843 St. Peter am Kammersberg Autriche info@cooolsport.com
