What Our Clients Are Saying

  • cbr carbon fiber rim client review 001
    Ethan

    I'm glad that I got a chance to try the CBR 26-inch mountain bike rims. The rims look nice. I didn't have any trouble building a wheel with a carbon rim compared to aluminum. The ERD measurement listed on the website said 516 mm but it was actually longer so measure twice before ordering spokes.

    The riding experience with a carbon rim is improved over previous rims I have used because of the reduced weight and improved stiffness. I had no trouble with this product and I would recommend these rims to anyone looking for carbon rims in this price range.

  • cbr carbon fiber rim client review 002
    William

    I am really glad that I got the chance to try the CBR 700c carbon road bike rims. I sent the rims to the bike shop and they built it up for me. I used the Halo Spin Master 6D road bike hubs, DT spokes, and Shimano 5800 11-speed cassette for these rims.

    Like most of the carbon road bike rims, the Neway rims have a 50mm (about 2 inches) deep V-shape profile with a 23mm wide rim bed. Both wheels have 24 holes. The rims are pretty light. They also look nice and provide a good riding experience.

About Products

Carbon rims are more sensitive to tire pressure and can crack under high pressure or hard impacts with low pressure, unlike alloy rims that may only dent. Proper attention to tire pressure is crucial to avoid damage to carbon rims.

While tire pressure is often a matter of personal preference, each rim has a recommended pressure range. Generally, wider rims or larger tires require lower pressure. The ideal air pressure should be high enough to prevent frequent rim bottoming but not too high that it makes the tire uncontrollable. On technical terrain, it's recommended to increase air pressure a few psi to prevent excessive rim strikes.

Checking air pressure before each ride is essential to prevent damage to the rim and ensure optimal performance. Consider your weight, riding style, tire choice, rim width, and terrain to determine the appropriate tire pressure. Good judgment is key in maintaining the health of your carbon rims.

UD, 3K, and 12K are just three different weaving types of carbon fibers that are widely used for manufacturing bicycle products. There are lots of debates online about the difference between carbon weaves of UD, 3K, and 12K. People who are just new to carbon fiber products maybe not know much about it.

UD is short for Uni-Directional, the fibers of UD weave are arranged in one direction, which is the most frequently used to make carbon fiber products. 3K means there are 3,000 filaments per "tow", and 12K means there are 12,000. They are decussated like a web. 3K weave carbon fiber is the most well-known.

The different weaving way makes the carbon fibers in different appearance and performance.

Appearance:
The illustration is as below, it shows different appearances of the weaves, and bicycle rims in different weaves. UD weave looks like plain black. Crossed 12K weave pattern is 4 times larger than the 3K weave. Customers may also know 1K, 6K, 18K, and 24K. They are also decussated/crossed, just in different sizes of the pattern.
what is the difference between weaves ud, 3k, and 12k
When it comes to fitting wheels onto your bike, it's generally safe to assume that road wheels will fit a road bike, and gravel wheels will fit a gravel bike. However, it's important to consider tire width and clearance between the tires and the fork/seat stays. To ensure a proper fit, start by measuring your tire width with calipers.

Next, use a set of Allen keys as feeler gauges to check the clearance at the chain stays, fork crown, and rear brake bridge. Once you find the wrench size that fits and the next size up doesn't, you have your clearance number for your existing setup. Keep in mind that Plus wheels will usually have wider and taller tires than those on narrower rims, so a 3mm clearance minimum is recommended.

If your bike frame is older (5-10 years old, depending on the manufacturer), it may not have the same level of tire clearance as more modern frames. Be sure to take this into consideration when choosing tires and wheels for your bike.
Asymmetrical and symmetrical rims differ in their design and drilling. Asymmetrical rims are specifically designed to compensate for the offset design of most hubs, resulting in more even spoke lengths, a stronger wheel build, and less truing than traditional rims. On the other hand, symmetrical rims utilize standard drilling practices and do not account for the offset hub design, resulting in a wheel build that may not be as strong as an asymmetrical build but is a more cost-effective option.
Free Coating Manufacturing process is a newly developed process in manufacturing carbon fiber rims, with no sanding or finish coating process conducted on the rim surface. Rims get polishing treatment right after the raw ones come out from the rim molds. The FCM process has been quite mature, All of our carbon fiber rims now are available with the FCM process. The advantages of an FCM-processed rim are lighter weight. scratch resistance. environment-friendly.
For all the Ultralight Edition rims and Premium Edition rims, we do make improvements over traditional tech (Standard Edition)) carbon fiber bicycle rims.

1. Materials: T1000 carbon fiber added to some Ultralight Edition rims, and/or T800 carbon fiber added to Premium Edition rims;

2. Optimized the layup system mixing T700 & T800/T1000 carbon fibers after many times of producing, testing, producing, and testing, found the best impact resistance over durability and tenacity.

3. We made a single mold to layer up the spoke bed wall. The flatness of the rim channel surface significantly improved so that the thickness at each spoke hole was completely consistent. It effectively prevents the carbon loop of the spoke hole wall from shifting;

4. Each rim would be attached with a card showing the flatness and roundness. The flatness and roundness are controlled quite well. Flatness is controlled within (+/-0.15mm), and roundness within +/-0.2mm, is easier to tune when doing wheelset assembly;

5. Three-year warranty offered for Ultralight and Premium Edition rims.
