MRP
Mountain Racing Products (MRP) is the Colorado brand that effectively invented the modern chain guide. Its legendary SRS (System Roller Slider) set the template every downhill and enduro guide has followed since, and chain guides remain the company's number-one product line. From CNC alloy plates with bright orange rollers in the late 1990s to today's composite and carbon guides, MRP has kept drivetrains on the chainring for three decades.
