The MRP SB-3 Slalom Chain Device w/Alloy Outer Ring is a budget version of the System 3. It offers all of the chain retention of the patented Twin roller MRP system with a rotating outer plate, but uses a robust steel back plate and a 5mm thick outer disc. It fits most MTB frame designs and set-up is simple, without the inner plate, allowing for more standard fits offering ISCG and non-ISCG mounting options.
