Air-cooled drum brake 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 ( "Flat" and "Highend" ) can be used.
