The EXAR Ultra wheelset is engineered for optimal performance, incorporating top-tier materials from spokes to bearings to craft a sophisticated hub and rim. Whether considering aesthetics, quality, or speed, the EXAR Ultra has been elevated to a superior level, with nuanced details propelling riders to the forefront on the field.

Integrated Design for Enhanced Lightweight and Speed

Riders seek wheelsets that are lighter, stiffer, and faster, and EXAR engineers have met this challenge with the Ultra wheelset to enhance race speed. Utilizing HI-MOD T800 carbon fiber and employing an integrated and systematic design, the wheelset achieves a substantial reduction in weight while maintaining exceptional stiffness. This translates to a smooth start and accelerated performance for riders.

Innovative Front and Rear Wheel Design

The EXAR Ultra wheelset introduces a novel concept with a lower front wheel and a higher rear wheel. This design not only preserves the high inertia of the rear wheel but also ensures control over the front wheels, enabling more efficient and stable riding.

Aerodynamic and Comfortable 30mm Width Rim

Designed exclusively for a disc brake structure, the 30mm width rim with a 23mm internal width optimizes aerodynamic performance in varied wind conditions, enhancing stability, particularly in crosswinds. When paired with a 28-32c tire, the flattened contact surface between the tire and rim creates a more aerodynamic profile, contributing to increased cycling comfort.

Ultra-Stiffness with Full Carbon Fiber Spokes

The EXAR Ultra carbon fiber wheelset features HI-MOD T800 carbon fiber spokes, each weighing only 2.8g—30% lighter than top-tier steel spokes. These carbon fiber spokes exhibit higher tensile strength, withstanding 30% more tensile force and minimizing strength loss during transmission. The 2:1 balanced lacing pattern ensures optimal tension distribution, with 130kgf±10% on the rear-wheel drive side and 110kgf±10% on the non-drive side.

Ceramic Bearings for Smooth Durability

Opting for lightweight and low-resistance ceramic bearings over steel, the EXAR Ultra wheelset ensures smoother performance, saving energy and facilitating rapid acceleration. The carefully processed contact surface of the bearing and body enhances precision and synergy.

Flat Engagement Ratchet for Durability

The wheelset incorporates a 36-tooth flat ratchet, ensuring tight engagement with a larger surface for increased durability, swift and precise engagement, and stability.

Enhanced Flange Diameter for Extended Endurance

Scientifically calculated flange diameter considerations, in conjunction with carbon fiber spokes, reduce stress concentration points where the spokes meet the hub. This enhancement improves driving stiffness and extends overall endurance.

Professional Endorsement: UCI Approved

The EXAR Ultra wheelset has undergone rigorous testing and received UCI approval, meeting the demanding standards set by professional riders who demand peak performance and reliability.
