Premium Edition CGX Series (25mm Internal) Wide Gravel Bicycle Carbon Fiber Rims

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 CGX series of our gravel bicycle carbon rims are wider than traditional size. Wider rims allow you to go for wider tires, more confortable. In the year of 2023, we upgraded the weight of CGX gravel rims, they are around 15g lighter than previous versions. The weights are listed as below:

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.

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.
