Walker Brothers “WideBoy” range wheel sets have an extra wide 28mm braking surface width which widens out to a maximum of almost 30mm. They have an angled 4 degree braking surface and when fitted with 25mm tyres gives an excellent aero profile of tyre and rim combined.
The “WideBoy” wheel sets are targeted more for road bikes as there may be clearance issues with some TT frames that have limited brake caliper adjustment. If purchased for TT frames the clearance should be checked before purchase.
Chris King R45 Ceramic was chosen the as the top of the range hub for the Fleet Wheelsets. The R45 rear hub combines a redesigned RingDrive™ system with 45 teeth for lower drag and near instant engagement with a lightweight hub body and the legendary made-in-house bearings. Ceramic bearings, roll on heat-treated, surgical grade steel races that are machined simultaneously, with tools of equal wear to ensure perfectly matched inner and outer races. The quality and speed of the bearings is what sets it apart from the competition and they are what you will feel and notice on every single ride. As Chris King bearing tracks burnish they get faster with age and all our hubs and bearings are fully serviceable for years upon years of demanding use. The patented Chris King RingDrive with 45-points of simultaneous-engagement will get your power to the ground fast, provide unmatched engagement, and give you that legendary Chris King angry-bee sound. Inside the sleek hub body is a stiff 17mm alloy axle for superior performance under the lateral stresses encountered in corners and aggressive sprints. The hub is 11-speed Shimano and Campagnolo compatible. Unique to the R45 rear hub is the King patented 45 tooth RingDrive engagement system, creating a quieter, faster engaging freehub body.
