Introduction
In the relentless pursuit of carbon fiber bicycle rim innovation, NEXTIE continues to break boundaries. Now please allow us to introduce this top-level newly designed road rim —— Alpha 40.
For top-level road bike rims, it is different from mountain bike rims. Light weight is not the primary goal for road rims. The goals of road rims are to achieve a balance between optimizing the weight of the rim and ensuring a certain rotational inertia, excellent dynamic balance, sufficient stiffness to make the rim achieve a smaller deflection, better wind-breaking performance to increase riding speed, and greater strength. The newly launched Supreme Edition Alpha 40 carbon road bike rim embodies our revolutionary solution, incorporating multiple core technological innovations.
1. Advanced Single-Point (ASP) Reinforcement at Spoke Holes and Valve Stem Hole, Rims being Lighter and Stronger.
2. Material Breakthrough: Toray T1100 + M46J Aerospace Grade Carbon Fiber, Further Improving Performance.
3. Newest Layer-up Structure: All-Wrapping Technology & Optimize Wheel Weight Distribution to Improve Wheel Rotation Inertia.
4. Highly Strict Technical Test Methods.
