SGV Series – Supreme Edition Super-Wide Gravel Carbon Rims (32mm Internal)

With the booming development of gravel bike in recent years, gravel bikes are becoming more and more popular among cyclists, mainly because they can be ridden almost anywhere, on the road and off it. Gravel-related bicycle products are also constantly upgraded and expanded to meet a wider range of riding needs. The change of gravel bicycle wheels is one of the biggest improvements.

Wider rims can be installed with wider tires, thereby improving riding stability and grip. Lighter rims can make riding easier. Our carefully crafted SGV carbon fiber gravel rim series just meet these new product needs. The SGV series remain 6 different heights, and the internal width is uniformly designed to be 32mm. As the newest series of products, we manufacture these rims with the high module carbon fiber material Toray T1000 added. The combination of SGV rims with new materials greatly reduces the rim weight while ensuring sufficient strength.

Core Innovations

1. Wide Profile for Modern Gravel Riding.

The SGV series features a 32mm internal width, purpose-built for modern gravel and adventure riding. Wider rims allow you to run wider tires with more air volume, lower rolling resistance, greater cornering grip and improved ride comfort.

2. Toray T700 + T800 + T1000 Carbon Fiber.

SGV series uses a combination of Toray T700, T800 and T1000 carbon fiber materials as its main structural material. This material system allows us to control the rigidity and deflection of the rim within 0.2mm — a very high accuracy for a gravel rim, without sacrificing strength.

3. Tubeless-Compatible Design.

Lower rolling resistance. By eliminating the inner tube, the friction between tire and tube is also eliminated, allowing the tire to 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.

4. Highly Strict Technical Test Methods — 100J / 110J / 120J (UCI Test Standard).

We applied the UCI test conditions to test SGV series carbon rims. The impact test results reached 100J for SGV 39, 110J for SGV 44 and 49, and 120J for SGV 54, 59 and 64. All results are much higher than the UCI's baseline strength requirement for bicycle rims. IMPACT TEST VIDEO.

Whether it is fearlessly challenging new and nasty gravel terrain on weekends, or simply tackling with daily commuting, a gravel bike equipped with the SGV wheels can allow you to easily cope with it and to enjoy the new riding fun.
