KOIBIKE 46mm carbon road rims offer enhanced traction and stability, reduced drag, and exceptional stiffness. Their versatile design opens up endless riding possibilities. If tubeless tires are used to reduce overall weight, they can be installed airtight with bead tape, reducing rotational weight and minimizing the risk of flats. They also allow for lower tire pressures for improved traction and vibration damping, making them ideal for endurance riding and high-speed cornering. These braking road rims are compatible with both rim brake and disc brake systems. Rim brakes offer high-temperature resistance, while disc brakes offer convenient and fast braking. The rim profile enhances speed retention on flats and descents. These carbon road rims are available in a variety of spoke counts (16-36H) and premium finishes (unidirectional, marbled, 12K, and twill), making them ideal for custom and high-end wheel sets. Whether you're building a competition-grade brake wheelset or upgrading to a wider, higher-performance tubeless-ready wheelset, KOIBIKE is your most trusted OEM/ODM partner and the best choice.

KOIBIKE: A leading Chinese carbon wheel manufacturer, established in 2015. With over 10 years of expertise in carbon fiber bicycle parts, KOIBIKE is a trusted OEM/ODM partner for global brands.

The EM-MA28X38HL-29ER-UL is a structurally evolved carbon rim developed by KOIBIKE specifically for endurance racing and high-intensity all-mountain riding. Its 38mm diameter accommodates tires sized 2.1- to 2.6-inch, and its 28mm structural depth provides a stable balance between lightweight and impact resistance. Weighing 490 ± 15g per rim, it utilizes high-modulus Toray carbon fiber with an impact energy dissipation ply to effectively absorb high-frequency impact forces during continuous descents, rock ledges, and jumps. The 3mm offset spoke holes optimize tension distribution and enhance the wheelset's structural consistency under asymmetric loads. It supports tire pressures from 18–30 psi and is tubeless compatible, making it suitable for modern low-pressure, wide-tire strategies. Available in four finishes: UD, marble, 12K plain, and 12K twill, it meets both performance and aesthetic needs.

-1) 2 grams super light carbon fiber bicycle bladed spokes for road/gravel/MTB bike wheels. -2) Titanium made of thread and nut, lighter weight, better quality and stability. -3) T head design, better fitting, locking and stability to match with T head design hubs. -4) Glue-free mechanical locking pultrusion technology, no glue required nipples, never fall off. -5) Light weight, high stiffness, high spoke tension and fatigue resistance, less maintenance costs.

*88mm depth rims are highly aerodynamic, reducing drag and allowing for faster speeds, especially on flat or rolloing terrain. *19mm inner width, 26mm outer width tubeless structure design, can reduce rollowing resistance, further enhacing speed. *The 88mm carbon tubeless wheelset is primarily designed for speed and aerodynamic efficiency, making it ideal for time trials, triathlons, and flat, fast courses.

-1) Aerodynamic streamlined design with 3 spoke, reduce the drag, allows for high speed races with less effort. -2) The solid structure and T800 fiber provide excellent stiffness, which translates to efficient power transfer. -3) With Toray T800 high quality materials, make the trispoke wheel a light weight, which contributes to overall performance and acceleration.
