MRP, the leader in chain management devices, introduces the new 2x guide for 2-chainring MTB cranks (say ";two-by";). In development for almost two years, the 2x utilizes our patented integrated skid chainring protection and introduces a new patent-pending dual pulley tensioning system.
The 2x is designed to work seamlessly with the new wave of 2x10 drivetrains being specified on many new mountain bikes. These new 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.
