Carbon Bicycle MTB Rim Test

Carbon Bicycle MTB Rims

There are several types of carbon bicycle MTB rims available on the market. Each type has its own unique features and is suitable for different riding conditions.

1. Tubeless Ready Rims: These rims are designed to work with tubeless tires. They offer several advantages, such as lower rolling resistance, better traction, and the ability to run lower tire pressures without the risk of pinch flats.

2. Clincher Rims: Clincher rims are the most common type of rims. They use a tire with an inner tube, which is held in place by the rim's bead. Clincher rims are generally more affordable and easier to maintain.

3. Hookless Rims: Hookless rims are a relatively new design. They eliminate the traditional hook on the rim, which can reduce the weight and improve the aerodynamics of the wheel.

Testing of Carbon Bicycle MTB Rims

1. Tension Test of The Spoke Holes

1. Standard tension (shall be no cracks and bulges)

2. Note: Touch the rims to check if bulges on the rims when testing. According to the drilling angle to test.

   

2. Resist Compression Test From The Forward Direction

1. Test conditions:

   Applying strength to the rims until the maximum of rims can withstand, speed 25.4mm/min.

   Rims placed: as valve as center, down placed the rims.

2. Test standards:

   rims depth > 30mm, damage > 90kg;

   rims depth < 50mm, damage > 200g;

   rims depth ≥ 50mm, damage > 300kg;

3. Test result description:

   According to test conditions，applying strength to 300kgf, test once, no apparent abnormality of the rim.

3. Resist compression test from the side direction.

1. Test conditions: The carrying capacity to 25kgf, keeping 1 min;

2. Test standards: Applying strength ≤ 50kg, there shall be no visible cracks or fracture on the rims;

3. Test result description: According to test conditions: applying strength 60kgf,no apparent abnormality of the rim.
