Developed for Aerodynamics and Lightweight
With a rim profile of 45 mm and a weight of only 1150 grams, the Artech 4.G is the fastest and lightest aero gravel wheelsets developed for pure gravel purpose, without compromising on stiffness and durability.
Besides best in class aerodynamics and an extreme low weight, the Artech 4.G provides high lateral stiffness and doesn’t compromise in durability. The Artech 4.G offers a 28 mm internal hookless tire bed, optimized for a variety of gravel tires from 35 up to 83 mm.
Exceptional engineering
by creative minds
We think differently, more creative and from new perspectives. We pioneer new technologies and bring a new way of thinking into the cycling industry.
The Artech breaks industry norms with unparalleled performance to offer the best wheelsets on the market, anytime.
Algorithm Enhanced Aerodynamics
The shape of our rims is defined by our Algorithm Enhanced Aerodynamics (AEA) technology. This algorithm optimizes the most aerodynamic rim-profile guaranteeing optimal aerodynamic performance.
Surface Structure Aerodynamics
The Aeroscales generate velocity streaks travelling at different speed over our rim surface. This has a stabilizing effect on the airflow and reduces drag.
Lightweight design
With our Local Reinforcement carbon technology, we’ve increased the number of carbon layers around the spoke holes on the inside of the rim. This way we significantly reduce weight while preserving strength and stiffness.
Perfect tire-fit
The unique geometry of our Scope Tubeless System ensures easy mounting, direct inflation, long-lasting pressure and compatibility with all clincher and tubeless tires.
Lightweight 3D printed
The lightweight bone like hub structure design is a result of topology optimization. Using Scalmalloy material in combination with the latest 3D-printing technology we’ve been able to manufacture this unique, lightweight and strong hub design.
Lightweight and durable
The Diamond Ratchet SL system is made from titanium and finished with a diamond like carbon coating. This results in direct engagement, improved durability, and a significant reduction in weight.
Ultra-light and Aerodynamic
The lightweight Carbonlite Aerospokes provide high lateral stiffness resulting in increased efficiency when accelerating and climbing. The optimized aerodynamic shape of the spoke reduces aerodynamic drag.
