La llanta asimétrica Bola 700C de 45 mm para gravel/carretera con freno de disco: una llanta tubeless de 45 mm de perfil medio y 30 mm de ancho, con un ancho interno de 24-25 mm, diseñada para gravel, all-road y ciclocrós con frenos de disco.
Creada para el constructor de ruedas con frenos de disco que busca una única llanta para afrontar rutas de gravel, días de all-road y el barro del ciclocrós por igual.
Guía de compra.
Nivel de peso - ligero ~360 g (Ultraligero): para carreras de gravel rápidas y ascensos, priorizando la aceleración sobre el margen de resistencia a impactos.
Nivel de peso - superior ~435 g (Ligero): para un uso intensivo en gravel y ciclistas más pesados, sacrificando un poco de peso por mayor robustez.
Ancho interno - 24 mm con pestañas (hooked): para cubiertas de 28-40c a ~50-75 PSI, ideal para ciclismo de carretera de resistencia y gravel rápido.
Ancho interno - 25 mm sin pestañas (hookless): para cubiertas de 38-50c a ~30-45 PSI, ideal para gravel irregular y barro de ciclocrós.
Serie de mismo perfil: la llanta para tubular de 45 mm (310 $) es una opción para carreras de carretera con neumáticos pegados; la llanta de 45 mm de 34/28 mm (310 $) cuenta con una base moderna mucho más ancha.
Perfiles adyacentes: la llanta de 30 mm para gravel/CX (310 $) es más ligera y estable con viento racheado; la llanta de 50 mm y 30 mm (310 $) aporta mayor aerodinámica en llano.
Solo para montajes con freno de disco; respete el límite de peso del sistema.
Público objetivo y notas de uso.
Constructores de ruedas DIY, mecánicos, ciclistas de gravel y cualquiera que necesite reemplazar una llanta dañada.
Esta es una llanta individual (bujes, radios y cabecillas se venden por separado).
Cuadros de gravel/CX de carretera con frenos de disco; espaciado de 142x12 o 135x9 según la elección del buje.
Peso máximo del sistema de 110 kg.
No apta para uso intensivo fuera de carretera/MTB.
La experiencia que te espera.
Apúntala hacia una pista de gravel y el montaje con desplazamiento (offset) se asienta en una trayectoria segura, con la base ancha flotando sobre las irregularidades del terreno a baja presión.
Te sentirás conectado a cada piedra pero aislado de lo peor de ellas, trazando más rápido de lo que el terreno debería permitir.
El envío gratuito y una garantía de 3 años en la llanta te respaldan desde el primer día de polvo hasta el último.
Specifications
- Material: Carbon fiber
- Rim depth: 45mm
- External width: 30mm
- Internal width: 24-25mm
- Size: 700c
- Profile: Asymmetric
- Weight Tier: Lightweight (360-435g)
- Max Tire Pressure: 90
Trade-offs & Considerations
- Aero vs Climbing: 45mm depth provides good aerodynamic efficiency on flats but adds weight (~380g) compared to shallower rims, making steep climbs slightly less effortless.
- Stiffness vs Compliance: Asymmetric carbon layup offers high lateral stiffness (≥8N/mm) for power transfer, but this can transmit road buzz; however, the wide 24-25mm internal width allows running lower tire pressures (e.g., 30-40 psi on 40c tires) to improve compliance.
- Tire Volume vs Speed: The 24-25mm internal width supports tires from 33-50c, maximizing volume and traction for gravel, but wider tires increase rolling resistance and reduce aero efficiency compared to 28c road tires.
- Price vs Grade: At ~$310, it offers a mid-range price with performance comparable to higher-priced rims, though the carbon grade (unidirectional + woven) and warranty (3 years) reflect a balance of cost and durability.

FAQ
How do I set up this rim tubeless?
Use tubeless tape (e.g., 25mm wide) and a tubeless valve (6.5mm). Ensure the rim bed is clean and dry. Mount a tubeless tire, seat it with a compressor or high-volume pump, and add sealant (about 60ml per tire). The rim is designed for tubeless and has a bead lock for secure seating.
What tire sizes are compatible?
The 24-25mm internal width supports tires from about 33mm to 50mm wide. For gravel, 40-45mm tires are ideal; for road, 28-35mm. Always check the tire manufacturer's recommended width range for your internal rim width.
How much weight can I save by using this rim?
Compared to a typical alloy rim of similar depth, this carbon rim saves around 300-400g per wheel. The rim weighs between 360g and 435g depending on width and drilling, whereas a comparable alloy rim often exceeds 700g.
Can I build this rim with any hub?
Yes, it's a standard 700C rim with a 622mm bead seat diameter. It's compatible with most hubs and spokes. Ensure you use the correct spoke length based on your hub and lacing pattern. The rim is drilled for either 20, 24, 28, or 32 holes, depending on the option.
How do I maintain this carbon rim and avoid damage?
Regularly inspect for cracks, delamination, or impact damage, especially after hard rides. Clean with mild soap and water, avoid harsh chemicals. When mounting tires, use tire levers carefully to avoid damaging the bead. Over time, check spoke tension and true the wheel as needed.
