Introduction of KOIBIKE's New 36MM Outer Width Carbon Gravel Rims:
The 36mm outer width carbon fiber rims are our new developed series for all-road and gravel bikes, rims were with 30mm internal width and tubeless designs, which offer a balance of aerodynamics, stiffness and compliance, making them versatile for various riding conditions, the 30mm internal wider tubeless were designed to accommodate wider gravel tires from 35C to 55C, improving grip, comfort, and puncture protection.These wheels are designed to handle both smooth pavement and rugged gravel trails, providing a responsive and efficient ride, especially suitable for long distance touring.
The rim depth are available from 32mm, 42mm to 52mm, the mixed depth(e.g. front 42mm+rear 52mm) of front and rear offer a balance of aerodynamics and handling, making them a good choice for various gravel riding conditions. A deeper rear wheel enhances speed and aerodynamics, while a shallower front wheel improves stability, especially in crosswinds. This setup provides a good compromise between speed and control, making it suitable for both endurance rides and varied terrain.
The G32X36TL, G42X36TL and G52X36TL gravel rims were with two weight versions, SL refers to super light version, which have no limits for riders' weights, UL means ultra-light version, which were applied with Toray T800 high quality and premium carbon fibers and optimized layup design, maximum riders' weights are around 130kg, building with our 2 grams carbon spokes, 226 grams ratchet system hubs, the complete wheelset are only 1196 grams per pair based on the G52X36TL-UL model. The new carbon spokes Gravel wheels combined the advantages of carbon and steel spokes, which are features with light weight, aerodynamic, high stiffness, versatility and agility, suitable for different kinds of riding conditions and riders.
