Ultralight Stem Cap and Bolt

The Wolf Tooth Ultralight Stem Cap is a precision-engineered component designed for riders who believe every detail matters. Precision machined from high-strength 7075-T6 aluminum, this ultra-sleek cap provides a flush fit with your stem or can be used with a spacer, delivering a professional finish without any performance compromise.

Elite Lightweight Performance: Weighing only 8 grams for both the cap and the included black alloy bolt, this setup offers a substantial weight saving over the 18-gram industry standard. This ultralight construction ensures you maintain the lowest possible weight on your cockpit while benefiting from the durability of premium-grade aluminum alloys.

Universal Compatibility: Designed to fit 1 1/8" top steerer tubes—including both straight and tapered 1 1/2" to 1 1/8" configurations—this cap is a versatile addition to any modern bike. It pairs perfectly with anodized color kits and specialized headsets, allowing for a fully customized look that matches its high-end technical specifications.
