The MRP 1x guide for seat tube mount is the definitive cross-country and cyclocross 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 or riders wishing for more security out of their "narrow/wide" or XX1/X01/CX1 setups.
- tracked and grooved upper guide / backplate interface increases stiffness and eases installation
- perfectly suited for 1x10 and 1x11-speed drivetrians
- suited for 28.6, 31.8 & 34.9 mm seat tubes (rubber shims included)
CX - chainline 40-42 mm (for inner chainring position on road double cranks)
MTB - chainline 49-51 mm (for middle chainring position on MTB Triple cranks). MTB version features significantly more vertical adjustment, due to the small chainrings that will be used (32t is common) and the large quantity of carbon bikes with flared seat tubes at the BB junction.
All install and adjustment operations possible with just a single 4mm HEX wrench.
