Air-cooled drum brakes for fast cars and mountainous topography. The basis for this hub is the Sturmey Archer drum brake X-SD. By mounted heatsinks hub can dissipate a lot of heat energy. So the brakes are less thermally stressed and the spoke tension can not fall so much. This extends the life of the wheel increases. The air-cooled + hub is available in various configurations. Make sure when choosing your vehicle. For the assembly of carbon caps only specimens with machined outer flange can be used.
