The R45 series is Chris King's response to market demand for a purpose-built road racing hubset. The R45's predecessor, the "Classic" series, was originally designed for mountain use, and merely adapted to standard road widths. Overbuilt bearing seals and the patently loud ratchet system that made these hubs so popular for mountain bikers hindered their success in the road market. Reengineering of that classic design has yielded a hub set with lower seal drag, quieter operation, and a 20% lower overall weight. The R45 hubs are also available in the lower spoke hole counts popular in modern road wheel sets. As with all of Chris King's products, these hubs feature immaculate finish work; the hub shells are highly polished prior to anodizing, which yields a deep, vibrant hue to each of the ten color options.
The R45 front hub features a super stiff 17 mm aluminum axle for superior performance under the lateral stresses that are encountered in cornering and hard sprints. The stainless steel in-house manufactured bearings are fully serviceable using simple tools. Detailed service instructions are included.
Chris King products are manufactured with pride and confidence in Portland, Oregon, USA. R45 hubs are covered under a 5 year warranty against manufacturing and materials defects.
