The 2x is designed to work seamlessly with the new wave of 2×9/10/11 drivetrains being specified on many new mountain bikes. These drivetrains created new challenges to chain management with their unique gear ratios, chain lines, and impact protection requirements. The 2x solves all of these challenges. To create the 2x guide, MRP began the process of applying our range of technologies and systems to find the optimal solution for 2x drivetrains, and through collaboration with SRAM and extensive testing it was decided that the ultimate light weight solution was a chain guide sharing elements of the G2sl, LRP, and XCG products. Notable is the absence of an outer capture ring on the cranksets, relying on the front derailleur and lower pulley assembly for complete chain retention. MRP’s design goals are driven by the passion to design and produce products that allow riders to just ride – not worrying about chain damage or dropping a chain.
