The new 2x guide for 2-chainring MTB cranks. In development for almost two years, the 2x utilizes MRP's 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. To create the 2x guide, MRP began the process of applying our range of technologies and systems to find the optimal solution for 2x10 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.
The integrated skid protects the chainrings from impacts without the added weight of a full bash ring. The dual pulley tensioning system ensures that the chain is properly tensioned and in the right position, keeping it on the chainring in the roughest conditions. The dual pulleys also reduce drag and noise compared to other designs, ensuring a better riding experience. Finally, the raised top fin profile prevents the chain from dropping to the BB shell.

Chain devices fit in various places around a mountain bikes transmission and help to eliminate chain suck and chain slap when riding over rough terrain or landing from big drops. There are a number of fitments, some frames have ISCG mounts which are lugs on the drive-side of the bottom bracket shell and allow direct fitment to the frame, other chain devices fit in between the bottom bracket and frame and require a specific bottom bracket with a larger drive-side cup, and finally there is the type that clamp around the seat tube in place of the front mech. Also within this section you can find single speed chain tensioners which fit in place of the rear mech and take up any chain slack.There is also a selection of wheel tugs which stop you pulling your wheel over in horizontal dropouts.
MRP have been producing high quality cycle chain guide systems since 1996. MRP guides are the consistent choice of the world’s best riders in every discipline on the mountain. Just ask the legends of the sport what chain guide they insist on using year after year. The answer is always ""MRP"" for their quality, dependability, and reliability.
