The Renegade Derby Cover is a stunning two piece engineered design. This allows our customers to choose the perfect combination of finishes to complete their bike with. The Derby Base Plate and the Derby Cover are machined from T6061 aircraft aluminum by craftsmen here in the USA. Both the base & cover come in show chrome or black anodized phantom cut and of course we offer cover designs to match all our Renegade or HHI wheel designs.
