Wolf Tooth Ultralight Stem Cap and Bolt

Wolf Tooth Ultralight Stem Cap and Bolt is a refined finishing component for riders who understand that every detail matters in a high-quality bike build. Clean, minimal, and precisely machined, this stem cap delivers a flush interface with your stem while reducing unnecessary weight at the cockpit.

Machined from premium 7075-T6 aluminum, the Ultralight Stem Cap balances strength and durability with impressive weight savings. At just 8 grams total—including the alloy bolt—it cuts more than half the weight of a standard stem cap and steel bolt setup, without compromising performance or reliability.

The low-profile design sits flush with most stems for a seamless appearance, or it can be paired with a spacer beneath it depending on your stack configuration. Available in a range of anodized finishes, the Wolf Tooth Ultralight Stem Cap is an easy way to add subtle color coordination while maintaining a purposeful, performance-focused aesthetic.
