Integral Design, No Sub-Assemblies
Instead of being a combination of components and sub-assemblies, EXAR carbon fiber wheelsets are quality and high-performing products featuring an integral design of appearance, weight, and performance.

Lighter Always with You
EXAR Pro series rims are made of HI-MOD carbon fiber. While keeping the rim, spoke and hub stiff, we optimized materials and structure to reduce overall weight. The light design effectively reduces driving weight and improves sprinting performance. Automatic carbon fiber winding technology is applied, therefore, the carbon fiber is prestressed and is more straight and evenly forced. The stiffness and consistency of wheelset are ensured. *The wheelset weight does not include the weight of quick-release bar and rim tape; A tolerance of ±3% applies to the weight, and the actual wheelset weight should prevail.

Flat Engagement Ratchet, Ensure Stable Performance
Adopt 36-tooth flat ratchet, which has tighter engagement with larger surface. This can make the ratchet more durable, with fast and precise engagement as well as stability. The rotating sound is more even with flat wire spring. It’s highly free that you could replace the original ratchet with other ratchet of different tooth amount.

Wider for Better Aerodynamics
Pro series wheelsets have an external width of 27mm and an internal width of 20mm. The 27mm wide rim provides a flatter aerodynamic surface with 25c and 28c outer tires and thus reducing air resistance.

UCI Approved
EXAR Pro series wheelsets have passed UCI impact tests. After applying an energy of 40 J on the bare carbon rim, the deviation complies with UCI standard.

Unique Design of Rim
To improve the wheelset stability, stiffness and crosswind resistance of different frame heights, targeted wheel rim designs were made. For disc brake wheels, symmetric structure is adopted and the flange width is optimized so that the spoke tension on both sides are close to the same. The cross-sections of Pro series wheelsets are redesigned for greater stability and rigidity.

Elaborate Hub Structure
The rear-wheel hub WR size is increased to ensure the spoke tension on the driving side is consistent with that on the non-driving side, hence to deliver outstanding lateral stiffness. Adopting FEA technology and conducting several tests to identify the maximum force on the hub, to get a light and sturdy hub. To obtain a better balance lateral stiffness, driving stiffness and braking effect, the front and rear spokes of the disc brake variants have applied a 2:1 balanced lacing pattern, and the hub geometry has been adjusted accordingly. The rear-wheel drive side flange diameter is increased and the spoke direction is aligned with the torque direction and the wheelset driving efficiency is improved.

Balanced Design of Spoke Tension
For both front and rear wheels of the the disc brake wheels, the 2:1 balanced lacing pattern is applied to reasonably distribute spoke tension and enhance the pedalling force. With a standard design of highly stiff spokes, the spoke tension of all models of rear-wheel drive side is 120kgf ±10%, with vigorous and powerful treading.

More Powerful Design
The Pro series feature Pillar Wing21 flat spokes for excellent performance of aerodynamics and driving stiffness. The self-locking spoke nipple for both internal and external use is applied, where the nipple is tighter and the spokes are not easy to loose. Support tubeless tires and clincher tires. Tubeless rim tape has been attached at the factory so that tubeless tires can be installed directly.
