Eccentric crank

When you have limitation in the knee or hip, for example a limited ability to bend your leg (max. 45 degrees), an eccentric crank will allow you to make a different rotation movement with this leg, while the other one continues to make a regular pedal movement. This way your complaint will no longer impede your ability to cycle. Here you can download the order form for an Excentric Crank from Van Raam.
