Road Carbon Rims ARX Series 31mm

On the road, riding wider wheels equate to a faster roll, a more subdued and smoother ride quality, and noticeably improved cornering grip with a more confident feel at the limit. This is why more and more cyclists are opting for wider wheels. As market demand continues to expand, we have developed the ARX series carbon fiber road rims, which are wider than the CRX series, to meet the riding needs of more road bike enthusiasts.

carbon road bicycle wheels and cycling experience

We made 8 types of ARX rims in a variety of depths to adapt to different usage environments, 29mm, 34mm, 39mm 44mm 49mm, 54mm, 60mm and 65mm, in style of clincher hookless version and hook version. All of these rims are tubeless-compatible. You may use these rims for road, triathlon, cyclocross, dirt, gravel, and adventure riding. 

Quality is what we have always guaranteed. Rigidity and deflection control are the most important factors in measuring the quality of a road bike rim. Because of the use of better carbon fiber materials, Toray T700+T800, and the latest manufacturing technologies, we are able to control the rigidity and deflection of premium edition road carbon rims within 0.2mm. This is a very high accuracy.

Hook and hookless versions are both available for these ARX series carbon rims. The tire size for these rims is recommended at 28 ~ 60mm. The tire pressure is recommended at 60 ~ 95psi.

In the year of 2023, another two models were developed to meet the market needs. They are the NXT60ARX 60mm depth rim and the NXT65ARX 65mm depth rim.

Advantage of Wider Wheels

Wide rims mean riding lighter, smaller performance tires with cushiony, high air volume and firm surface grip. Rolling resistance is lower with wider tires. Cornering grip is greatly improved. Ride comfort is greatly increased.

Aerodynamic Optimized Design

Nowadays, aerodynamic performance is one of the key factors considered when racing cyclists purchase new equipment, as the aerodynamic drag is known to be the main source of losses in cycling. The aerodynamic optimization of bicycle wheels can lead to decisive gains in running pace. For all of our CRX carbon rims, they have an optimized cross section. Please also note that choosing an appropriately sized tire for an aerodynamically optimized rim is also crucial to reducing air resistance and increasing riding speed.

Tubeless-Compatible Design

Lower rolling resistance. By eliminating the inner-tube, the friction between tire and tube is also eliminated, allowing the tire roll, flex, and conform to the road with greater efficiency.

Flat less, ride more. Flat tires are a buzz-kill. With a little sealant you can eliminate nearly all flats that would have been caused by an intrusive thorn or piece of debris.

Run the Best Pressure. Tubeless means you can run the pressure you want to maximize comfort, traction, and rolling efficiency. Visit our tire pressure page to dial in your best tire pressure.

Hookless Design

Tubeless performance depends on the tire maintaining a light press-fit with the rim on the bead seat diameter. We chooses a hookless tubeless rim profile as it allows the rim’s critical tolerance at the bead seat diameter to be both consistent and accurate. In short, hookless is chosen to deliver a more safe, reliable, and ultimately proper tire fitment.


We got UCI approval for our road rim NXT45RC. Learn more about the UCI Approval: UCI-APPROVAL
