The new 1x CS (Core Series) brings our 20+ years of chainguide expertise to a new price point. Taking design cues from our class-leading V3 family of 1x guides, the CS model utilizes a stiff and light glass-filled composite backplate and durable nylon upper guide to add major security to your 1x10, 11, or 12-speed drivetrain at minor cost. We’ve tested several backplate material formulations and zeroed in on a proprietary mix that delivers the high level of retention and security befitting the MRP name. Cost has been contained not through any short- cutting when it comes to quality and performance, only by the removal of a few of the bells and whistles found within our premium line.
