EXAR PRO SERIES 58 WHEELSET '25
Instead of being a combination of components and sub-assemblies, EXAR carbon fiber wheelsets Pro series are quality and high-performing products featuring an integral design of appearance, weight, and performance.
PRODUCT HIGHLIGHTS
- 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 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.
