La llanta de gravel Bola 700c asimétrica en carbono V: un aro de 30 mm de profundidad y 30 mm de ancho (335-405 g) en carbono Toray T700/T800 para gravel y all-road.
Para las jornadas largas de gravel, la comodidad y el soporte importan más que la velocidad pura. Un ancho externo de 30 mm proporciona un soporte lateral real a los neumáticos de gravel anchos, mientras que un desplazamiento asimétrico de 2,6 mm equilibra la tensión de los radios.
Guía de compra.
Nivel de peso - Ultraligero ~335 g: el montaje orientado a la escalada para ciclistas más ligeros de unos 80 kg; rápido en ascensos de gravel con carga.
Nivel de peso - Superligero ~365 g: el modelo polivalente para ciclistas de hasta ~95 kg; para competir y rodar sin márgenes mínimos.
Nivel de peso - Normal ~405 g: el montaje resistente para ciclistas de hasta ~105-120 kg; elígelo para bikepacking y caminos en mal estado donde la durabilidad es lo primero.
Ancho interno - 24 o 25 mm: elige el más estrecho para un neumático de competición más ágil, el más ancho para un neumático de gravel voluminoso de baja presión en pistas irregulares.

Carga la bicicleta para un largo día de gravel y siente cómo la llanta absorbe las vibraciones: neumáticos anchos, baja presión, una rueda que transporta tu equipaje sin quejas. Rueda sobre pistas irregulares con serenidad, absorbiendo piedras que harían vibrar una llanta estrecha. Elige la estructura que se adapte a tu carga y deja que la garantía de 3 años de la llanta asuma el riesgo.
Specifications
- Material: Toray UD carbon
- Rim depth: 30mm
- External width: 30mm
- Internal width: 24/25mm
- Size: 700c (ISO 622)
- Profile: Asymmetric V-shape
- Weight Tier: Normal 405g, Superlight 365g, Ultralight 335g
- Max Tire Pressure: 90
Trade-offs & Considerations
- Weight vs Durability: Choose from 405g (Normal), 365g (Superlight), or 335g (Ultralight) per rim. Lower weight reduces rotating mass for climbing but decreases load capacity and durability; Normal tier supports up to 120kg rider weight, Ultralight only 80kg.
- Tire Volume vs Speed: 30mm outer width supports 32-54mm tires for comfort and traction on gravel, but the wider profile increases drag compared to narrower aero rims. The 30mm depth favors stability over pure aero efficiency.
- Stiffness vs Compliance: The asymmetric 2.6mm offset and Toray T700/T800 construction provide lateral stiffness for precise handling, while the wide rim bed and tubeless setup allow lower pressures for compliance. However, stiffness is not as high as deeper-section rims, trading some responsiveness for ride comfort.
- Versatility vs Specialization: This rim is designed for gravel, endurance, and all-road use, accommodating various tire widths and tubeless setups. It is not optimized for pure road racing aerodynamics or heavy-duty MTB use, making it a versatile but not fully specialized choice.

Recommended Use Cases
- Gravel Racing: Good choice for mixed-terrain racing with wide tire support and reliable construction.
- Bikepacking: Good for loaded adventures; Normal tier supports up to 120kg rider weight for heavy loads.
- Gran Fondo / Endurance: Suitable for long rides with comfort from wide tire compatibility and tubeless setup.
- Road Racing: Not recommended; 30mm depth and wide profile lack aero efficiency for competitive road racing.
- Training / Daily Riding: Suitable for everyday riding; durable construction and tubeless compatibility make it practical.
- Not Recommended For: Heavy-duty MTB downhill or track use; this rim is optimized for gravel and all-road, not aggressive off-road or velodrome.

FAQ
How do I set up this rim tubeless?
Use a standard 6.5mm tubeless valve and tape the rim bed with tubeless tape. The hookless bead design ensures a secure fit. Inflate the tire to seat the bead, typically requiring a compressor or high-volume pump. Recommended tire pressures range from 30-50 psi depending on rider weight and terrain, but always follow tire manufacturer guidelines.
What tire widths are compatible?
The rim supports tires from 32mm to 54mm wide. The 30mm outer width provides strong sidewall support for wider gravel and all-road tires. The inner width is available in 24mm or 25mm, allowing a good range of tire volumes. For optimal performance, consider tires around 40-50mm for gravel riding.
How much weight can I save compared to an alloy rim?
The carbon rim weighs between 335g and 405g per rim depending on tier, while a comparable alloy rim often weighs 500-600g. This saves 100-200g per rim, reducing rotating mass and improving acceleration and climbing. The specific savings depend on the alloy rim you compare against and the chosen weight tier.
Can I build this rim with any spokes or hubs?
Yes, the rim supports custom spoke drilling for straight-pull or J-bend spokes with a 4.5mm nipple seat. This allows compatibility with a wide range of hubs and lacing patterns. Ensure you use appropriate spoke lengths for your chosen hub and lacing pattern. The asymmetric 2.6mm offset improves spoke bracing angle for disc brake wheels.
How do I maintain and inspect this rim for damage?
Regularly inspect the rim for cracks, delamination, or impact damage, especially after rough rides. Check spoke tension and true the wheel as needed. Avoid overheating the rim by using rim brakes for long descents; this rim is designed for disc brakes. Clean with mild soap and water, and avoid harsh solvents. The three-year warranty covers manufacturing defects.
