EXAR Ultra Wheelset is Designed for Ultimate Performance
The wheelset is fully equipped with top-level materials from spokes to bearings, creating an elaborate hub and rim. No matter in terms of appearance, quality or speed, EXAR Ultra has been improved to a higher level.

Integral Design, Lighter and Faster
Riders want wheelsets that are lighter, stiffer, and faster. EXAR engineers have risen to the challenge with Ultra wheelset to help riders ride faster in the race. The EXAR Ultra wheelset applies HI-MOD T800 carbon fibre, following the integrated and systematic design. The primal materials allow a great reduction in weight while retaining outstanding stiffness. These help riders get a smooth start and faster acceleration.

Lower Front Wheel and Higher Rear Wheel Design
The EXAR Ultra wheelset features a new design concept of a low front wheel and a high rear wheel. While ensuring high inertia of the rear wheel, also keeps the controllability of the front wheels, allowing the rider to ride more efficiently and stably.

More Aerodynamic and Comfortable
A 30mm width rim and 23mm internal width are purely designed for disc brake structure. It ensures optimal aerodynamic performance in complex wind conditions, improving stability in crosswinds as well.
After installing the 28-32c tyre, the contact surface between the tyre and rim is flat. As a result, It creates a flatter aerodynamic surface and enhances cycling comfort.

Full Carbon Fiber Spokes, Contribute Ultra-Stiffness
EXAR Ultra carbon fibre wheelset features HI-MOD T800 carbon fibre spokes. Each spoke weighs only 2.8g, 30% lighter than top-level steel spokes. Carbon fibre spokes have higher tensile strength and can withstand 30% more tensile force. Lower strength loss of transmission brings higher driving efficiency.
The wheelset applies a 2:1 balanced lacing pattern, which distributes tension perfectly. The spoke tension of the rear-wheel drive side is 130kgf±10%, and the non-drive side is 110kgf±10%.

Ceramic Bearing, Smooth and Durable
Compared to steel, ceramic is lightweight with low resistance, which can be used to make smoother bearings. A well-made ceramic bearing has lower resistance, thus saving you energy and allowing rapid acceleration.
The contact surface of the bearing and body is processed with smooth edges to create precise synergy.

Flat Engagement Ratchet Design
Details reveal the optimal configuration. Adopt a 36-tooth flat ratchet, which has tighter engagement with a larger surface. This can make the ratchet more durable, with fast and precise engagement as well as stability.

Improve Flange Diameter, Extending Endurance
The flange diameter has been calculated scientifically in terms of the stiffness of carbon fibre spokes. We reduce the amount of stress concentration point where the spoke contacts with the hub, thus improving driving stiffness and extending endurance.

Professionally Tested, Approved by UCI
Pro riders are the best test of the wheelset. They demand the highest performance and most reliable wheelset design. The EXAR Ultra wheelset has passed the UCI impact tests. After applying an energy of 40J on the bare carbon rim, the deviation complies with UCI standards, helping professional riders lead the field.
