As I never really liked the Coerce sprocket covers and I was bored and also had a spare sprocket cover.....well you should be able to guess what happened next.....
First drill a bunch of holes....
Get rid of the big extra bit.....
After a little die grinder and dremel practice.....
Finally a bit of paint and superleggera sprocket cover ....
