The new CS (Core Series) line from MRP brings our 20+ years of chainguide expertise to new price points. CS-level models are now available in the 1x, AMg, SXg, and G4 guide families.
They feature all the performance or their premium alloy and carbon siblings, but use either glass-filled composite or premium finished steel backplates. Unlike other guides found at these price points, the CS models feature co-molded upper guides for silent chain retention and alloy guide hardware.
