Description
Introduction
In 2024, we completely redesigned the RX series road bicycle carbon rims. The inner width has been updated from 18mm in the old versions to 19mm. We have also made a comprehensive upgrade based on the old version, and the weight has been further reduced.
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.
The weight of RX 45 is only 360g. The profile drawing is as below.
The tire size for this model of rim is recommended at 22 ~ 40mm Road / 28 ~ 40mm Cyclocross. The tire pressure is recommended at 47 ~ 116psi Road / 28 ~ 56psi Cyclocross.
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 RX 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.
