This is a carbon fiber mountain bike wheel set designed for off-road riding scenarios, with a focus on high performance and compatibility.
♦Key features ⇓
◦ Braking method: Dual specifications of 6 bolts/center lock, compatible with mainstream disc brake systems.
◦ Freehub body compatibility: Supports mainstream drivetrain freehub body specifications such as Shimano 11-speed, Sram XD, and Shimano Micro Spline.
◦ Axle diameter specification: MTB boost specification (front 15×110mm, rear 12×148mm), enhancing wheel set rigidity and stability.
-
Spoke Parameters: Adopts SA-1423 spokes with both aerodynamic and high-strength properties, reducing wind resistance while ensuring wheel set durability.
-
Appearance Craftsmanship: The carbon fiber surface treatment offers 3K/UD/12K carbon pattern options, with both matte and glossy surface finishes available
- If you require a lighter and better configuration (for ceramic bearing or spoke like pillar 1420, sapim cx-ray), please contact us for an upgrade
This is the MD02 series hub for mountain bikes, available in two braking specifications: 6 bolts and center lock, featuring lightweight design and high compatibility. 
♦Key features ⇓
- Specification Compatibility: Adopts MTB boost axle spacing (front 15×110mm, rear 12×148mm), compatible with mainstream mountain bike frames and forks. It supports two disc brake mounting methods (6 bolts and center lock), meeting the needs of different braking systems.
- Structural Upgradeability: The ratchet structure is 36T by default and can be upgraded to 54T, improving engagement speed and transmission efficiency, suitable for high-intensity pedaling scenarios in off-road riding.
- Lightweight Design: The hub body is made of lightweight materials. The center lock version has a front hub of only 139.2g and a rear hub of 261.7g, effectively reducing the rotational inertia of the wheel set and improving riding maneuverability.
- Bearing Configuration: Equipped with high-precision 6902/6903/18307 series bearings. The freehub body and hub are equipped with independent bearings respectively, ensuring smooth rotation and durability for long-term use in complex road conditions.
1. High-Strength Performance: The AS-blade flat spoke has a breaking strength of 420-450kgf, far exceeding ordinary round spokes. It can withstand the stress of high-intensity riding scenarios such as off-roading and racing, improving wheel set stability and durability.
2. Lightweight Design: Each spoke weighs only 6.5-7.5g and each spoke nipple weighs 0.3-0.4g. Combined use can greatly reduce the rotational inertia of the wheel set and improve riding acceleration and climbing efficiency.
3. Specification Compatibility: The spoke length covers 200-310mm, adapting to bicycle rims of different sizes; the spoke nipple is a standard 14G 14mm specification, compatible with the assembly needs of most spokes and rims, with strong versatility.
4. Aerodynamic Advantage: The flat spoke shape has less wind resistance than traditional round spokes, which can reduce air resistance during riding and improve speed performance at high speeds.
