C washers

If your bike has quick release wheels with a ridge around the dropouts (like pictured below), you will need c washers to chock up this space, so the axle nut has a good solid surface to tighten onto.

This is only necessary for the Grunt and Smart kits, whose wheels have 14mm axles (with shaved sides, to slot into 10mm dropouts).  Other kits with 12mm axles normally don't require these, as the washers supplied will fit into this space.
