A gummed up drivetrain is a slow drivetrain. Finish Line's Speed Bike Degreaser uses a powerful solvent to quickly remove grease, grime,and other organic elements from your bike, without scrubbing. It leaves no residue and doesn't use water so that there is no rinsing required. More impressive, it dries so fast you're able to re apply lube to the chain and cassette right away so you'll be back out riding fast. The Finish Line Speed Bike Degreaser comes in a 17oz can with mechanical agitation for added cleaning power.
