Terra Labs. Ultra X 50 — Engineered for Speed, Stability, and Durability
The Terra Labs Ultra X 50 is the ultimate all-terrain performance wheelset, designed for riders who demand aerodynamic efficiency, durability and control across every surface — from smooth tarmac to rugged gravel.
At its core is a hooked carbon rim with a 32mm internal width, purpose-built to support larger tire formats from 2.0 to 2.25 inches. This wide stance enhances stability by reducing tire deflection and increasing air volume, allowing lower pressures for improved traction, comfort, and confidence on any terrain.
The 41mm external rim profile delivers a proven aerodynamic advantage, promoting smoother air attachment and reduced drag, so you can maintain speed and efficiency even in challenging wind conditions.
New to the Ultra X 50 is a bead lock system that simplifies tubeless setup, ensuring a secure, airtight seal whether you’re fitting tires in your workshop or trailside. This system enhances reliability and minimizes burping, giving riders peace of mind on every ride.
Every element of the Ultra X 50 is built for strength and longevity. A reinforced nipple bed allows for higher spoke tension, increasing stiffness and durability under demanding loads. High-quality Bladed Pillar spokes deliver precise handling, efficient power transfer, and lasting performance.
Constructed from T700 high-modulus carbon fiber, the Ultra X 50 balances lateral stiffness with vertical compliance, maintaining comfort without compromising responsiveness. Lightweight, robust, and aerodynamically refined — the Terra Labs Ultra X 50 sets a new benchmark for modern endurance and gravel performance.
