Designed and exclusive to MSC Bikes. The new and improved Freedom Rotation Crankset allows independent movement of the front and rear crankset on a tandem bike. A simple solution which is lightweight and easily used on other Tandem bicycles. The front uses a 39T chainring and the rear a triple (22x32x42t) with both crank arms 170mm in length.
The Freedom Rotation Crankset comes as standard gear on our Zion Tandem MPS2
