  • [TX] Classic Road Carbon Rim Tubular 30mm


The RX road bike rims are a series of road rims in classic size. They are premium edition and made of the materials of Toray T700+T800 carbon fibers. They are aerodynamic optimized design, could efficiently break the wind, so they could be ride very fast.

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 NXT30TX is only 300g. The profile drawing is as below.

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.
