Description

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 AGX series carbon rims are the widest rims we've ever made for gravel bicycle, strong and light, meeting the needs of elite gravel riders, racers and cycling enthusiasts. The AGX series provides a stable platform for wider gravel tires from 35mm to 70mm. This series are aerodynamic designed in width and depth dimensions, delivering a fast cycling speed. 

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 AGX 45 is only 430g. Hook and hookless versions are both available. The profile drawing is as below.

Recommendation of Tire Size and Tire Pressure.

Tire Size (Hook): 33 ~ 40mm Cyclocross / 33 ~ 72mm Gravel

Tire Size (Hookless): 38 ~ 40mm Cyclocross / 38 ~ 75mm Gravel

Tire Pressure (Hook): 24 ~ 38psi Cyclocross / 20 ~ 60psi Gravel

Tire Pressure (Hookless): 22 ~ 30psi Cyclocross / 19 ~ 48psi Gravel


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.

I bought AGX 45 hookless rims with custom decals and smaller holes for internal nipples.
Production time was estimated 3-4 weeks and shipping with tax prepayed another 2 weeks to Germany. The time estimate turned out to accurate.
For my custom wishes I contacted the customer service wich accompanied the entire process and kept me updated all the time. The time to answer was mostly less then 24h.
The quality and the finish of the rims were very good and up to specifications.
I build up the wheels with DT Swiss 350 hubs, Sapim CX Ray Spokes and Sapim Brass upside down nipples. The build trued up well and was overall nice to work with.
I used the Specialized Pathfinde Pro tire in 38 mm which was easy to mount and kept the pressure well. On the rim they measured 41mm.
Overall I am really happy with the way this project turned out and can honestly recommend the product and the service I recieved.
I will update this after some longer time of testing :)

I was looking for an aero gravel wheel and was considering the 3T Discus 40/45, but couldn’t stomach the price. 3T claim they have the widest aero gravel wheel, but they must not know about Nextie’s 45 deep AGX wheels which are internally 1mm WIDER (hookless) with the same width and depth externally. Nextie provides many more build options for about half the price of 3T’s wheels…

My AGX wheels were built up with black brass nipples, Sapim CX ray spokes laced to Onyx Vesper hubs. The wheels trued up with ease and have maintained their form perfectly with over 1k miles of hard riding - Rocky Mountain single track and rocky Jeep roads. I currently have the Challenge Strada Bianca 40mm tires mounted and with the combination of this fast tire and the super aero profile of this rim, these are by far the fastest wheels I have ridden.

I cannot recommend these wheels enough!

ich finde die abmessungen dieser felge sehr spannend... eine bewertung ist mir leider im augenblick nicht möglich, da ich sie ja noch nicht habe und daher nicht testen konnte
