Stealth Cage UD Carbon

What Our Gearhead® Experts Are Saying:

"I’ve tested plenty of carbon cages, and this one stands out for its balance of stiffness and usability. It holds bottles firmly through chatter and hard hits, yet I can still grab a bottle one-handed without fighting it. The low weight is impressive, but it’s the consistent retention that keeps it on my bikes."

The Stealth Cage UD Carbon is engineered for riders who expect performance from every component, no matter how small. HiLine designed this cage to thrive under high-speed, high-vibration riding, where bottle security isn’t optional—it’s essential. Its sleek silhouette adds visual refinement without distracting from the bike’s lines.

Constructed from premium carbon fiber, the cage delivers exceptional stiffness-to-weight performance, tipping the scales at just 28 grams. The carbon layup is tuned for firm retention, preventing unwanted ejections during rough descents, sprint efforts, or fast gravel chatter, while still allowing intuitive bottle access mid-ride. Standard mounting compatibility makes it an easy upgrade across road, gravel, and mountain platforms.

Whether you’re building a race-ready gravel rig, dialing in a lightweight XC setup, or refining a clean road build, the Stealth Cage UD Carbon is a smart choice for riders who demand security, efficiency, and understated style on every ride.
