Bracciano A42 42mm Full Alloy Aero Wheelset Small flange hubs for light weight, rolling on Japanese EZO bearings for low rolling resistance. Easy to service with two allen keys. Using our patented spoke braces which effectively increase the size of the flange for better power transfer, meaning when you pedal the force created isn’t lost in the wheel and propels you forwards. The spokes are at a special 90° bend and butted, meaning they are stronger than a standard spoke. We also use washers made with a special material against the hub flange so the spokes fit flush and this reduces lost power.
