NFS Blue Devil is made for the most extreme conditions without compromise. Designed for gravel and road riding in challenging conditions. This would be the one stop shop for rides like DK, 600k Brevet in the rain or RAAM.
Blue Devil is not perceptively heavier than NFS Ultimate Chainlube you know and love. Blue Devil is made to outlast even NFS Ultimate when put head to head while keeping to the tradition of suuuuper quiet chains that run clean.
Blue Devil Formula is the Ultimate gravel and road chain lube.
