MRP 2X Dual Ring Chain Device Black

MRP is one of the industry leaders in chain management devices and now their all-new 2X guide brings their patented integrated skid chainring protection and introduces the dual pulley tensioning system to 2-chainring mountain bike cranks. This fantastic chain device has been in the making for two years and during that time MRP have refined and advanced the design to ensure this is one of the highest performing devices for 2012. 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. In the development of this chain guide, MRP have applied a range of cutting-edge technologies in order to give you the ultimate solution for 2x10 drivetrains. Through collaboration with SRAM and extensive system, MRP have concluded that to deliver amazing lightweight the 2X needs to share elements of the G2sl, LRP, and XCG products. 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 with ease. Notable in the design of this MRP chain guide is the absence of an outer capture ring on the cranksets, relying on the front derailleur and lower pulley assembly for complete chain retention. The integrated skid provides superb protection for the chainrings against any impact, without adding the full weight of a bash ring. What's more, the dual pulley tensioning system ensures that the chain is properly tensioned and in the right position, keeping it on the chainring even in the roughest conditions. The dual pulleys also reduce drag and noise compared to other designs, ensuring a supreme riding experience. To complete this outstanding guide, there's a raised topfin profile which prevents the chain from dropping onto the BB shell.
