Hope zs55 40 g headset bottom assembly

Product Description Durable and reliable: the ZS55/40 G Headset Bottom Assembly by Hope The Hope ZS55/40 headset bottom assembly is distinguished by its reliability and durability. The reason for this is the corrosion-resistant stainless steel bearing and the rubber seal. In addition, the headset cup is made of high-quality aluminium. The crown race is slotted to facilitate assembly.

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)Manufacturer Number:black:HSCGContents:1 x Hope lower headset cup incl. stainless steel bearings1 x crown race1 x O-ring Manufacturer: Hope Mill Calf Hall Road Barnoldswick Lancashire BB18 5PX United Kingdom info@hopetech.com Distributor: bc GmbH Carlo-Schmid-Straße 12 52146 Würselen Germany info@bike-components.de
