It's what a lot of people have been waiting doublering configurations - and big bottom bracket SRAM BCD owners who may have been struggling to find a compatible device, in particular. You don’t need an outer bashguard thanks to the removeable lower skid plate, while the twin jockey wheel setup should help prevent the chain coming off the bottom of the rings. The back plate is made of aluminum and has an 'end' to protect the fall of the chain on the inside too. You can get it finished with a BB, ISCG or ride ISCG05, white or black and is available in two sizes to fit 42 or 36 39T 38T outer rings.
