Description

Introduction

The carbon fiber bicycle industry has been innovating and advancing all the time. Being lighter and stronger has always been the pursuit of the professional bicycle industry, especially for the mountain rims for XC (Cross Country) riding, where riders have extreme weight requirements. The Supreme Edition was created to explore the performance and weight limits of carbon fiber materials applied to bicycle wheels. We know that different materials would affect the performance and weight of rim products. What if we change the appearance design of a rim? Would it bring any difference or improvements in the strength and weight?

We have found that the most vulnerable part of a rim is the rim lip. If we could enlarge the area of rim lip where it contacts the tire, in theory, under the same impact force, the pressure on a rim with a wider lip area would be less, which could perform a higher impact resistance. Based on this theoretical premise, we newly designed the Supreme Edition Omega 36U mountain bicycle rim for cross country with a rim lip thickness at 3.0mm.


The impact test result reaches 105J for the 280g version of Omega 36U. This is a huge improvement compared to the Premium Edition. IMPACT TEST VIDEO (280g).

On 2024.08.08, we successfully developed a lighter version of Omega 36U, the weight is 260g only. The impact test result reaches 100J. IMPACT TEST VIDEO (260g).

ChristianVerified Buyer September 3, 2026

I purchased a pair of Nextie Omega 36U Supreme rims for my XC mountain bike and I am very impressed. They are extremely light, stiff and responsive, and the 30 mm internal width works perfectly for my XC setup. The build quality and finish are excellent.

What impressed me even more was Nextie's customer service. I dealt with Alice regarding a couple of issues and her support was exceptional from beginning to end. She was always kind, responsive and genuinely interested in finding the best solution. Communication was quick and clear, and Nextie really stood behind their product.

Problems can happen with any product; what really makes the difference is how a company handles them. My experience with Alice and Nextie gave me great confidence in the brand.

Excellent rims and truly outstanding after-sales support. Highly recommended!
