Both the upper and lower SXg guides are made from nylon and have a TPU co-molded liner to help reduce noise. They also swing out to allow for easy installation or drivetrain maintenance, and are adjustable to accommodate different sized chainrings. The alloy unit we tested can accommodate chainrings from 30-34t. There’s also a 34-38t version.

The inside of both the upper and lower guides are lined with a TPU that helps minimize noise from chain slap.

We mounted our test unit to a Santa Cruz Bronson late last year and the process was painless. The guide mounted without the need for spacers and we’ve had zero issues with dropped chains. More importantly, we’ve banged our bottom bracket into landings, slammed into rock ledges, and crashed into downed logs without bending our chainring.

MRP’s approach with their new WhipperSnapper equipped SXg guide provides the benefits of a full chain guide without impeding drivetrain performance in the slightest. Even if you’re not a full time racer, we’re fans of the system for the peace of the mind and protection it affords. At just over a 100g for the carbon version or 150g for the alloy, it’s light enough to make you say why not for anything but the most XC oriented of builds.
