Lopes SL Brian Lopes is the most decorated 4X and Slalom racer in the world, not to mention multiple time DH champion in the USA earlier on. Brian has only ever used MRP chain guides during his entire career. It is from this great relationship that MRP have dedicated a new product to his name. Brian has always depended on MRP chain guides for reliability and at the same time asked us MRP the lightest possible chain guide. For racers like Brian Lopes looking for the lightest possible chain guide with both upper and lower retention but without bashguard protection, the Lopes SL will be the guide of choice. The Lopes SL utilizes the same upper and lower guide pieces from the G2 SL, but with a dedicated backplate and inner lower guide piece only found on the Lopes guide. It fits chainrings from 32T to 38T, and weighs just over 100 grams. BB, ISCG and ISCG-05 mounting options. Black.
