Problem
The mechanism of the folding frame has a lot of bearing points that are exposed to extreme loads when the bike is ridden off-road. The bike is exposed to all kinds of weather conditions. Therefore, the bearings must work perfectly in wet, muddy and dusty conditions and also cope well with temperature fluctuations. Due to the large number and generous dimensions of the bearing points, Thomas Schwaiger, aka "Tonkel Om", therefore needed a bearing material suitable for these loads, which also had to be as light as possible.
