A carbon fiber snow bike rim built for extreme winter conditions: 80mm wide for max snow/ice grip, 25mm tall for balanced stiffness and low drag. Tubeless-ready to avoid cold-weather punctures, disc brake-compatible for reliable stops. Lighter (40% vs aluminum) and -30℃ tough. Factory-direct with custom options—your ideal snow trail companion.

Product Features and Advantages

Snow-optimized performance:

80mm width amplifies tire-snow contact, boosting grip on ice/loose snow and minimizing sinking—ideal for deep powder.

Wide profile enhances lateral stability, reducing skidding when cornering on icy or packed trails.

Tubeless-ready design nixes cold-weather punctures, with adjustable air pressure for optimal adhesion to varying snow consistencies.

Disc brake compatibility ensures steady stopping power in snow/moisture, unaffected by ice buildup.

Seamless integration with wide snow tires prevents burping even under intense pressure.

Carbon fiber excellence:

40% lighter than aluminum, slashing rotational inertia for easier snow climbs and snappier acceleration, saving energy during long winter rides.

Lightweight nature makes maneuvering through tight snow-covered turns more responsive and effortless.

Withstands -30℃ extremes, boasting high impact strength to preserve rigidity on frigid, rough trails and resist cracks from sudden jolts.

Superior strength-to-weight ratio boosts durability without extra bulk, crucial for extended snow rides.

Resistant to corrosion from snow-melting salts, maintaining structural integrity and appearance over multiple seasons.

Practical additional features:

Offered via factory direct sales, cutting out middlemen to provide more competitive pricing.

Supports personalized customization, including options for colors, patterns, and spoke hole configurations (24/28/32 holes), allowing riders to tailor the rim to their unique style and bike setup.

25mm height strikes a balance between rigidity and aerodynamics, reducing wind resistance in snowy and windy conditions for a smoother ride.

Strict Quality Control:

KOBIKE do 100% tire pressure(150 PSI), flatness(＜0.2mm) and roundness(＜0.2mm) inspections before shipping, also offering 2 years warranty for our carbon rims.

Product Structure

Core rim structure:

25mm height profile: Crafted with a balanced cross-sectional design, combining vertical rigidity to handle impact forces from snow trails and horizontal flexibility for stable cornering.

80mm outer width: Features a slightly curved inner bead seat to securely lock wide snow tires, preventing slippage even under low air pressure settings.

Reinforced rim walls: Multi-layer carbon fiber layering enhances structural integrity, with thicker sections at stress points (e.g., valve hole and spoke holes) to resist deformation.

Material composition structure:

High-modulus carbon fiber layers: Arranged in alternating directional weaves (0°/45°/90°) to optimize strength-to-weight ratio, with additional resin infusion for cold-weather durability.

Anti-corrosion coating: A thin, weather-resistant film applied to the outer surface to protect against snow-melting salts and moisture, preserving the carbon fiber’s performance over time.

Connection & compatibility structure:

Standard spoke hole configurations (24/28/32 holes): Precisely drilled and reinforced with aluminum inserts to ensure secure spoke attachment and even load distribution.

Connection & compatibility structure:

Standard spoke hole configurations (24/28/32 holes): Precisely drilled and reinforced with aluminum inserts to ensure secure spoke attachment and even load distribution.

Disc brake mount integration: Machined mounting points (compatible with 6-bolt and center-lock systems) positioned to align with rotor dimensions, ensuring stable braking force transfer.

Tubeless valve hole: Strategically placed and sealed with a rubber grommet to maintain airtightness, supporting the tubeless tire system without air leakage in cold conditions.

Application Areas

Application areas for the FB25X80-24ER carbon bicycle rim:

• Professional snow trail riding:

Excels in alpine snowfields and backcountry trails, with 80mm width and tubeless design ensuring grip in deep powder/ice; carbon fiber’s lightness eases handling.

Ideal for snow bike racing: 25mm height balances rigidity and aerodynamics, while disc brakes offer reliable stopping in intense competition.

• Winter commuting:

Perfect for snow-covered urban roads—anti-corrosion coating resists salts, stable grip/braking reduces slips.

Handles luggage easily, thanks to reinforced walls and secure spokes for added weight.

• Recreational snow cycling: 

Great for family/group outings in snow parks; customization adds style, wide tires enhance comfort.

Enables exploration of snow-covered forests/countryside, with durability to adapt to varying snow conditions.

• Mountain bike snow adventures：

Fits snow expeditions: carbon fiber layers and reinforced stress points resist deformation from hidden rocks/stumps.

Suits technical descents—disc brake integration ensures precise speed control on steep, snowy slopes.
