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

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 rear wheel of the rim brake model is designed with an external width of 26mm and an internal width of 19.5mm for better compatibility with the caliper brake. 
The 27mm wide rim provides a flatter aerodynamic surface with 25c and 28c outer tires and thus reducing air resistance.

Braking Rim Dewatering Line Design

The unique grooved dewatering line of the rim brake wheelsets quickly drains water and improves braking performance. The braking rim is made of resin that be resistant to high temperature up to 240, eliminating the concern of rim blowing up or melting.

Uncompromising Stiffness

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 the 58mm deep rim brake rear wheel, a symmetric structure is adopted to prevent deflection due to uneven airflow.
  • 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 the rear wheel of the rim brake variant, and both front and rear wheels of the the disc brake variant, the 2:1 balanced lacing pattern is applied to reasonably distribute spoke tension and enhance the pedaling 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 Pro series with a rim brake come with carbon fiber composite brake blocks, providing excellent braking effect and less debris.
  • 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.
