The Speedplay Grease Gun makes re lubing your spindle bearings an easy task. It's a small bodied grease gun that takes a cartridge it comes with a 3oz tube of Sta Lube Marine Grease that fits inside the grease gun handle. Its needle tip allows direct grease injection in X, Zero, Light Action, and Frog pedals. For older X1 and X2 pedals, you'll need to install new dust caps with the provision for the needle tip. For all Speedplay pedals, just pump in fresh grease, purging the dirty grease until you see fresh stuff come out the other side. Wipe off the excess and you're ready to ride.
