What Our Gearhead(R) Experts Are Saying:"I pack my headset and seatpost with this before wet season rides. It stays put through stream crossings, and I can actually see contamination in the grease when it's time for a service."Stream crossings and rain-soaked descents put bearings through it, and Crystal Grease is built to keep water out no matter how deep the puddle gets. Pack it into a headset, seatpost, or bottom bracket, and its clear, non-staining formula goes on clean and stays exactly where it's needed, leaving nothing behind but smooth, quiet rotation.
