In Amoy Wheels,we have the tests standard for our carbon rim production.Usually,we have twelve kinds of tests on our carbon rims.Before each wheel is released it must have to pass all the testings including UCI vertical impact test,additional impact,stiffness,trueness,longevity test,frequency torque fatigue test and tire pressures test.With strict high-quality standards on the manufacturing processes and 100% quality test&check to guarantee all the rims greater than UCI/ISO Test standard.
Test Standards:UCI Vertical Impact Test
The impact resistance test shows the overall
structural performance of the wheels.Impact point
includes air nozzle,45°,90°,180°,270°,315°.The
striker (15.45kg) is dropped from a specific height
above. The higher the striker is raised, the greater
the impact force is.
Test Standards:Lateral Rigidity Test
The lateral rigidity test measures the stiffness or
rigidity of a bicycle rim in the lateral direction,
which is perpendicular to the plane of the wheel.
This test evaluates the performance and safety of
a bicycle wheel, particularly in racing or high-performance applications, where precise handling
and stability are critical.
Test Standards:Spoke Hole Tension Test
This test confirm that the key position around the
holes has been precisely reinforced during the
layup process.The rims are capable of
withstanding a spoke force of more than 300kgf
when hand built which offers better wheel
performance, durability and reliability.
Test Standards:Lateral Vertical Rigidity Test
The test is to predict the behavior of wheels by
precisely measuring the lateral vertical rigidity of a
raw rim. The test shows how well a rim resists
flexing and deforming laterally and vertically.The
stiffness of the rim can affect the responsiveness
of the bike, the control and stability of the ride,
and the transmission of power from the rider to
the road.
Test Standards:Compression Test
Carbon wheel compression test is conducted to
evaluate the ability of carbon wheels to withstand
compression and ensure that they are safe and
durable for use in cycling.The striker weight
120kg and compress rim for two minutes.The rim
deformation ＜1 mm, rim keeps inact and no
sound vibration.
Test Standards:Dynamic Balancing Test
The balance of wheels is very important during
riding.Unbalanced wheels would wobble at high
speed, which undermines the control ability of the
bike.We test the overall dynamic speed balance
of our wheels to make it more stable and higher
performance during riding.
Test Standards:Tire Pressures Test
We inspect the compatibility of rim and tire, the
ease of mounting and disassembly the tire, actual
tire width, and brake track deformation due to
inflation pressure.
Test Standards:Roundness & FlatnessTest
Assuring rims are accurately flat and round out of
the molds which means greater stability when
assembling the rims into wheels.If the roundness
of rim is imprecise,it would affect the spoke hole
tension and wobble under higher riding speed.
Test Standards:Brake Test
The test evaluates the braking performance and
heat tolerance of the rims.The result would be
affected by factors such as rim shape, brake track
material, and weather conditions.This test can
detect the safety and reliability of wheels during
riding.Braking temperature and braking distance,
were mainly adopted to reflect the qualification.
Test Standards:Wheel Building Test
All the defects of rims can be magnified during
wheels building process.If the spoke hole angle is
off,wheels would be wobbled.The wheel is
predictable and within tight tolerances.
Test Standards:X-ray Test
Through X-ray inspection,we can easily can
detect the abnormal layups,impurities, inner wall
shape, etc.
Test Standards:Rim Pieces Inspection
We gather all the rims pieces with quality problem
tto R&D department.Our researchers would
analyse these rim pieces and improve.
