The MRP 1x guide is the definitive cross-country chainguide. Used on the World Cup circuit and even in the 2012 London Games, the 1x has a proven track record of dependability and performance. The 1x is the perfect guide for riders and racers wanting a lightweight single-ring front drivetrain for cross-country use or riders wishing for more security out of their "narrow/wide" or XX1/X01 setups. The latest version has been freshly updated with a co-molded "TR" upper guide - lighter and quieter. With aluminium base plate. 
Notes:
All install and adjustment operations possible with just a single 4mm HEX wrench.
BB mounted version is only compatible with traditional, threaded BB systems
