These new guides look pretty sweet. We're currently running MRP systems on a couple of our bikes with great success. These look promising as an option for riders looking to keep the chain on without limiting gear range.
Here's what they have to say:
MRP, a leader in chain management devices, introduces the new 2x guide for 2-chainring MTB cranks. In development for several years, the 2x utilizes a patented chainring protection system as well as new patent-pending dual pulley tensioning set up.
The 2x is designed to work seamlessly with the new wave of 2x10 drivetrains being spec'ed on many new mountain bikes.
Extensive testing and collaboration with SRAM created a light weight chain guide solution sharing time tested technologies borrowed from the MRP product line.
Features:
• MRP's patented skid, removable for those who prioritize weight savings over protection
• Patent-pending dual pulley design provides precise chain engagement
• Raised top fin profile prevents the chain from dropping to the BB shell
• ISCG, ISCG-05, and BB mounting options
• Compatible with 9 and 10 speed drivetrains
• Available in black or white
