  • WATER DROP REINFORCED NIPPLE HOLE

    WATER DROP REINFORCED NIPPLE HOLE

    This design is our totally new idea. It comes from Chinese traditional arch bridges which are strong enough to stand more than 1000 years. With this design, our rim looks like combined with many different small arch bridges. The spoke hole beds are designed to like the piers of the bridge. So the total wheelset is supported by 28 pcs of piers. This makes the rims more impact resistant.

    IMPACT RESISTANT DESIGN(Hookless&trapezium tire bead design)

    Now, most MTB rims are with hookless design because of better impact resistance. Starting from this idea, we still make an improvement. The bead of our MTB rims is also hookless design, but it's not with an equal-thickness from top to bottom. We designed a wider thickness in the bottom to better "support" the impact. This design could improve the impact-resistance around 10%. We also work out a sp...

    CARBON BICYCLE RIM MID HOOK TIRE BEAD DESIGN

    CARBON RIM MID HOOK TIRE BEAD DESIGN For our disc brake specific rim family, we ultimately worked out a Mid-Hook design. With this technology, the rims could be as impact resistant as MTB rims, and they are around 80g lighter than rim brake models. however, they could take much higher tire pressure, as high as 90PSI with a 28C tire.

    CARBON WHEELS IMPACT TEST

    CARBON WHELLS IMPACT TEST This test is mainly for MTB wheels to make sure the rim's impacting strength is qualified. It will required 3 times impact at different position from a required impacting height. Different wheels would have different impacting height requirements. ● Test condition: air pressure 28psi, special shaped steel anvil go to impact the wheel directly from a certain height. The im...

    Carbon bike wheels BRAKE DISTANCE TEST&RIDING FATIGUE TEST

    CARBON WHELLS BRAKE DISTANCE TEST This test is reflect how the brake track and brake pads perform together. For a good rim brake wheel, we not only demand it to be heat-resistant enough, also wish to have a good braking performace with less noise and shorter braking distance no matter in dry or wet conditions. ● Test condition: Air pressure 120psi, load 100kgf , brake lever tforce 18kg, speed 25km...

    CRABON ROAD RIM INFLATION TEST

    Inflation test is very important for every rim brake clincher wheels, which usually apply a quite high tire pressure. If the rim could pass this test, it means the rim's structurer is strong&reliable enough, and it will reduce the wheel failure risks greatly.  every each YISHUN rim brake wheels have to pass this test. ● Test Condition: 150psi air pressure, test one time. ● Test Standard: ...
