Hubs

The Box One Stealth Expert Front Hub is designed to be light FOR lightweight riders, and features small hub flanges, lower spoke counts, and decreased material to keep the weight down. This makes the Stealth Expert Front Hub ideal for any Mini, Junior, or Expert wheel build, but may also accommodate a lightweight rider looking to move up to a pro-sized bike. FEATURES - Micro-Adjust Pre-Load Collar - Lightweight Design IMPORTANT NOTES Warning: The BMX spec is optimized for even lower drag with unsealed bearing. They are designed to be ridden in dry conditions. If ridden in wet conditions you will need to service the internals after each event or riding session. COMPATIBILITY - Box One XS Mini Carbon 1" Alloy Steerer 20" x 10mm Fork Black - Box One XE Expert Carbon 1” Alloy Steerer 20” x 10mm Fork - Box One 24x1-1/8" 28-Hole Front Rim Black - Box One 20X 1-1/8" 28-Hole Rim Rear Black

New Sheriff hubs are the ultimate in track racing hubs. They minimize weight with larger cutouts in the flanges, lightened axles, shorter bolts, and slimmer end caps than previous versions. The result is a hubset that weighs a mere 432g, 198g for the front, and 234g for the rear. This makes it one of the lightest track hubsets in the world, a figure even more impressive when you consider that All-City didn't eliminate the usefulness of a fixed / fixed or fixed / free option as most racing hubs do. They feature the finest Japanese manufactured 6902 bearings which roll incredibly fast and smooth while retaining excellent seals for all weather, all-day everyday durability. Front hub specs: - Weight: 198g - Torque Spec: 33nm (25ft lbs.) - Non-Drive Side Center to Flange: 34mm - Drive Side Center to Flange: 34mm - Non-Drive Side Flange Diameter: 62mm - Drive Side Flange Diameter: 62mm Rear hub specs: - Weight: 234g - Torque Spec: 33nm (25ft.lbs.) - Non-Drive Side Center to Flange: 29mm - Drive Side Center to Flange: 29mm - Non-Drive Side Flange Diameter: 62mm - Drive Side Flange Diameter: 62mm

WHY WE MAKE THIS Originally, we made this hub to be the cornerstone of our hub product line. It was one of those product releases where we put all our hub and bearing experience into, and ended up with a hub that struck that perfect balance between weight, performance, durability and looks. Since the advent of disc brakes (and the R45D), we keep making it, because it’s still that cornerstone hub, and so many of our riders still love to rock their rim brakes on road and off. WHY YOU WANT IT The R45 front hub is lighter and more aerodynamic than most built-to-last hubs on the market. Our R45 rear hub combines a redesigned RingDrive™ system with 45 teeth for lower drag and near-instant engagement with a lightweight hub body and our legendary made-in-house bearings. Our bearings, both steel and ceramic, have heat-treated, surgical grade steel races that are machined simultaneously to ensure perfect matching. The quality and speed of our bearings is what you will feel (and hear) on every ride. As Chris King bearing tracks burnish they get actually get faster. A little bit of regular love (i.e. service) will keep this hub rolling for years upon years of demanding use.
