The S4 is the latest update of the long line of MRP's dual roller chain guides, and it''s out to be the one of the best all-mountain and downhill guides out there. Actually living up to the all too oft-used ''bombproof'' label, the polycarbonate bash guard takes a pounding and keeps trucking while a honeycomb backside and face full of cutouts shed weight. A breeze to install, the dual roller design offers quiet, smooth, hassle-free retention. A thinner back plate offers more frame clearance, which means that more riders than ever can find out what world-class chain retention is all about.
