I've always hated those dumb little plastic air valve caps that come with most tires. They crack easily under stress, they're not always easy to grip, and they're easy to lose. (Can't tell you how many times I've dropped the things into tall grass and had to initiate a Honey, I Shrunk the Kids-style search mission.)

Not so with these stainless steel stem caps, though. They're longer than typical plastic caps and have textured knurling along their entire lengths so you never have a hard time gripping them, whether you're wearing gloves or have cold-numb hands in the winter.

They're precision CNC-machined from surgical-grade 316L stainless steel for extreme durability and corrosion resistance, and a food-grade silicone gasket inserted at the end completely seals the air valve from water, snow, and road dust to prolong the life of your tires.

No matter how harsh the weather conditions, no matter how much flying road debris they take, no matter how rough the terrain...you never have to worry about these things crumbling apart or allowing your tires' valve stems to become points of vulnerability. They also just look cool, so they're a super cheap and easy way to upgrade the look of your ride.

A set of four is $15 on Amazon and comes in your choice of black, gold, rose gold, stainless, or rainbow.
