It isn't a full chain
case, but is fairly full coverage, ( I added a cut down foam plate behind to give better protection for the chain. ) It can be a pain to fit, often needs some careful trimming as well, but cuts down significantly on the amount of crud on the drivetrain. Should use it with full coverage fenders for the best results.
