If you have a Speedplay Grease Gun and use it only to lube the spindles on your Speedplay pedals, chances are good that one cartridge of grease will last you a lifetime and beyond. However, the Sta-Lube that comes with the grease gun is good for just about everything that has moving parts and requires grease. So eventually you may need this Speedplay Grease Gun Refill. It's a 3oz tube of Sta-Lube Marine Grease that gets housed inside the grease gun handle. Because of its highly refined base oil and polymer formula, it's naturally water resistant and tacky enough to prevent washout. Use this versatile grease on your pedals, suspension pivots, hub bearings, etc.
