Chris King R45D Rear Hub – Centerlock – 12x142mm – 32 Hole – SRAM XDR Discount

The ultra lightweight R45 hub has been designed expressly for the demands of road racing with two objectives. It must be light an fast.The R45 rear hub is 15 % lighter than a Classic hub. Because Chris King has designed a sleek new hubshell body and a new 17 mm axle. That’s 17 mm from dropout to dropout resisting deflection during cornering or when the power is full on. Additionally Chris King has designed a driveshell with a twin bearing design that responsibly removed as much weight as they could from the inner components. Even Chris Kings patented RingDrive engagement system has been redeveloped resulting in a quiet, fast-engaging 45-tooth stainless steel system unique to the R45 rear hub.Furthermore Chris King designed and built a bearing specifically for the R45 hub. As with every King bearing, these stainless steel sealed bearings are made in-house in Portland, Oregon and individually hand-checked for precision and smoothness. This proprietary bearing design allows the developers to place more rolling elements per bearing meaning greater durability and precision. R45 bearings also feature lightweight, low-friction seals for fast rolling and can be easily serviced at regular intervals using only a single 2.5 mm hex wrench and penknife.Compatible with SRAM Red eTap AXS, Eagle AXS, and all XDR and XD cassettes.Ceramic bearingsClearance: R45 rear hubs can be used with 2-or-more-crossed lacing at the drive side and radial lacing at the non-drive side.Material: Aluminium 2024 T6, stainless steel bearingsWeight supplement: in relation to R45D XDR rear hub – Centerlock – 12x142mm – 28 hole)(weighed by Bike 24
