Light, Integral, Aerodynamic Design, Excellent Performance
EXAR carbon wheelset Standard 2022 has been upgraded in many aspects. It has lighter body, wider rim, unique braking rim design. To get the best stiffness, it adopts elaborate hub structure, rim design and lacing pattern.
EXAR standard series rims are made of T700 carbon fiber with special rim structure which offers an optimized blend of weight, strength and durability. The light design effectively reduces driving weight and improves sprinting performance.
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.
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 27mm wide rim is wider than most of the current wheelsets, providing a flatter aerodynamic surface with
25c and 28c
outer tires and thus reducing air resistance.
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.
The rear-wheel hub WR size is increased to ensure consistent spoke tension on both 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.
To obtain a better balance lateral stiffness, driving stiffness and braking effect, 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.
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.
The spoke tension of all models of rear-wheel drive side is 120kgf ±10%, with vigorous and powerful
treading.
