Forged cranks black anodised. These cranks do not have a connection for chainrings, so only suitable for bicycles where the chainring is on the bottom bracket.
This crank set is available in sizes 155mm and 170mm.
This folding bellow is also suitable for the Versatile.
For the other velomobiles such as Quest, Mango, Strada, Alleweder, WAW, Milan and others, see dimensions in the illustration if this is suitable.
