LIGHTER, ALWAYS WITH YOU EXAR Pro series rims are made of HI-MOD T800 carbon fiber with special rim structure which offers an optimized blend of weight, strength and durability. EXAR wheelsets are 70-160g lighter than most of other products of the same rim deep. 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. WIDER FOR BETTER AERODYNAMICS EXAR 2022 wheelset series have an external width of 27mm and an internal width of 20mm, which are wider than most of existing wheelset products. The rear wheel of the Pro series with a rim brake is designed with an external width of 26mm and an internal width of 19.5mm for better compatibility with the caliper brake. BRAKING RIM DEWATERING LINE DESIGN The unique grooved dewatering line of the Pro series 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. UNIQUE RIM DESIGN To improve the wheelset stability, stiffness and crosswind resistance of different frame heights, targeted wheel rim designs were made. The cross-sections of EXAR 2022 wheelsets are redesigned for greater stability and rigidity. ELABORATE HUB STRUCTURE The rear-wheel hub WR size is increased to ensure consistent spoke tension on bothe driving and 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. Balance Stiffness 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.
