This wheelset is a high-performance carbon fiber option specifically engineered for mountain biking and off-road scenarios. It consists of three core components: a carbon fiber rim, an aluminum hub, and stainless steel spokes, with "strong performance, high adaptability, and lightweight experience" as its core advantages, precisely meeting the demands of complex off-road terrains.

The rim adopts a 29-inch size, combined with a 25mm low-profile design, 35mm external width, and straight-side structure—striking a balance between lightweight and impact resistance, easily navigating obstacles while effectively preventing tire bead separation. The eccentrically arranged spoke holes ensure even force distribution, enhancing the wheelset’s durability.

The hub is made of extended aluminum alloy, featuring a 15100mm (front) / 12148mm (rear) thru-axle and a straight-pull structure for strong rigidity and direct power transfer. It also offers two options: ball bearings or ceramic bearings, catering to different budgets and usage scenarios.

The spokes are professional-grade Sapim CX-ray stainless steel, which boasts low wind resistance and high tensile strength. Paired with a 28/28-hole symmetrical layout, they further enhance the wheelset’s stability.

Overall, the wheelset fits most mountain bike frames and tires, balancing handling performance with easy daily maintenance, making it an excellent choice for mountain biking and off-road rides.

Product Features and Advantages

The 29-inch wheel size easily navigates obstacles like gravel and tree roots, boosting passing efficiency. The 35mm wide straight-side rim enhances wide-tire support, increases ground contact and grip, and effectively prevents tire bead separation under intense impacts. The 25mm low-profile design balances light weight and impact resistance, ensuring stable and safe riding on rough terrain.

Flexible Adaptability for Diverse Needs: 

The hub offers two options—ball bearings (cost-effective, ideal for daily off-road training) and ceramic bearings (low friction, suitable for professional competitions)—matching different budgets and scenarios without replacing the hub itself. With 15X100mm/12X148mm thru-axle specifications, it fits most mountain bike frames on the market, boasting strong compatibility.

High Durability for Long Service Life:

Eccentrically arranged spoke holes ensure even force distribution across each spoke, avoiding deformation or spoke breakage caused by localized tension concentration. Paired with Sapim CX-ray stainless steel spokes (high tensile strength and rust resistance) and a 28/28-hole symmetrical layout, the wheelset’s torsion resistance and fatigue resistance are significantly improved. The carbon fiber rim uses high-modulus material, balancing strength and toughness, and is not easily damaged during long-term off-road use.

Excellent Riding Experience: 

Balancing Performance & Comfort: The carbon fiber rim is 150-200g lighter per wheel than aluminum rims of the same specification; the overall weight reduction of the bike facilitates acceleration and climbing, making riding less strenuous. Meanwhile, the carbon fiber material filters high-frequency road vibrations, relieving hand and waist fatigue during long-distance off-roading. The combination of straight-pull hub and flat spokes enables direct power transfer, low wind resistance, and more responsive handling.

Thoughtful Details & Easy Maintenance: 

The rim’s inner wall is coated with an anti-scratch layer to prevent damage during tire installation; the hub’s flange is thickened to reduce wear from long-term use. The straight-pull spokes and selectable bearing structure allow daily maintenance without complex tools, making it easy even for beginners to operate.

Application Areas

Application areas for the XC-MW25X35HL-29-SS-UL carbon spoke wheel:

• Core Mountain Off-Road Scenarios:

Specifically designed for gravel roads, rocky slopes, and wild trails with dense tree roots. The 29-inch wheel size and wide rim easily handle complex obstacles, while its high rigidity and impact resistance can withstand bumps and impacts during off-roading—making it a core suitable choice for mountain wild riding.

• Trail Riding:

Adaptable to changeable forest trail conditions (such as soft dirt roads and short steep slopes). The shock-absorbing property of the carbon fiber rim relieves road vibrations, and the stable combination of Sapim spokes and thru-axle hub ensures precise handling during steering and sudden braking, enhancing comfort and safety for long-distance trail riding.

• Mountain Training/Daily Off-Road Commuting:

If you need to commute regularly on mild off-road sections on the edge of the city (such as unpaved suburban roads), the wheelset’s lightweight feature (reducing riding burden) and the cost-effectiveness of ball bearings (lowering maintenance costs) can balance training needs and the economy of daily use.

• Professional Mountain Race Support:

For amateur mountain competitions (such as off-road circuit races and short-distance mountain races), ceramic bearings can be selected to reduce transmission resistance. Paired with low-wind-resistance spokes and lightweight rims, it improves acceleration and climbing efficiency, helping to optimize race results.

• Lightweight All-Terrain Adventure: 

Suitable for short-distance mountain adventures (such as one-day mountain crossings). Its compatibility with most mountain bike frames and wide tires allows it to handle transitions from mild undulating roads to moderate off-road roads. The durable structure and easy-maintenance design also reduce the risk of malfunctions during outdoor riding.
