Product Description

Creator Derek Hermon has been tinkering with the (patent pending) design for six years, looking to create something that’s lighter, works better and is more versatile than the typical brass valve stems most of us are probably using. Anything that’s lighter and comes in various anodized colors immediately has our attention. When it promises to work better, too, we really perk up. He says they’re about half the weight, which means less rotating mass, particularly important on a part that can throw off the balance of the wheel, too.
