Lightweight Performance and Control
The EXAR Ultra carbon fiber wheelset is built for top-tier performance, combining HI-MOD carbon fiber with a sleek, weight-saving design for enhanced stiffness, smoother starts, and faster acceleration. Its unique lower front and higher rear wheel configuration strikes a perfect balance between stability and control, making it versatile for both climbs and flat terrain. The carbon fiber spokes, 30% lighter and stronger than steel, boost efficiency, while the 2:1 lacing pattern and concealed metal components reduce drag for optimal aerodynamics.
Precision Engagement and Aerodynamic Design
Equipped with a 36-tooth flat ratchet system, the EXAR Ultra series ensures quick, precise engagement and enhanced durability. The 30/32mm wide rims improve stability in crosswinds and, when paired with 28-32c tires, create a flat aerodynamic profile that adds comfort on varied surfaces. The hub’s optimized flange diameter and smoothly finished bearing interfaces maximize stiffness and longevity, while the well-calibrated WR size maintains balanced spoke tension for excellent lateral rigidity.
Smooth Rolling and Impact-Resistant
With low-resistance ceramic bearings, the EXAR Ultra wheelset allows for rapid acceleration and effortless rolling. UCI-certified for impact resilience, it supports both tubeless and clincher tires and comes with rim tape and plugs for weight reduction. Tailored for TPU inner tubes, this wheelset offers stable, high-speed performance, ideal for cyclists who demand reliability and efficiency.
