Cyclists, keep dirt and water out of your headset bearings with these simple but effective rubber caps! The 10-pack means you'll always have spares when one goes missing (because they always do). Just pop them onto unthreaded stems to prevent grit from wrecking your bearings. Works on mountain, road, folding, and track bikes. The black color blends in cleanly with any bike's look. Pro tip: Replace yours every season - at this price, there's no excuse for crunchy headset bearings!
