  • [GR] Classic Gravel Carbon Rim 40mm



Introduction

Gravel bikes can be ridden almost anywhere, on the road and off it. Adventure-ready features like disc brakes, additional clearance for wider tires, and comfortable geometry let these bikes adapt to everything from rugged terrain to winter exploration. These bikes are for the days when you're not sure where the journey will take you, but need the bike you know will get you there.

The GR series are the traditional gravel rims with internal width 22mm. They can be mounted traditional tires from 26mm to 50mm. They are standard edition made with T700 carbon fiber. For all premium edition rims, the deflection is controlled with in 0.3mm. 

The weight of NXT40GR is 440g. The profile drawing is as below. 

The tire size for this model of rim is recommended at 26 ~ 50mm. The tire pressure is recommended at 45 ~ 100psi. 


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.
