La llanta de carbono aerodinámica Bola de 120 mm de perfil: una llanta para contrarreloj/triatlón con perfil UV de 120 mm, 28 mm de ancho exterior / 21,5 mm de ancho interno, ~655 g, compatible con tubeless de gancho, para montajes de rueda trasera aerodinámica.
Una hoja de carbono de 120 mm equilibrada entre lo razonable y lo extremo: lo suficientemente profunda como para dominar un recorrido llano, lo suficientemente ligera como para seguir siendo, para los estándares de perfil alto, casi ágil.
Guía de compra.
Caso de uso: llanta trasera de perfil alto para contrarreloj y triatlón en terrenos llanos o ligeramente ondulados, más manejable que la opción de 180 mm.
Elección según el recorrido: elígela frente a llantas de menor perfil para mantener la velocidad en llano; sigue siendo más adecuada para recorridos protegidos del viento que para ascensos.
Elección de neumáticos: utiliza neumáticos de competición de alta presión de 25-28 mm en su base interna estrecha.
Serie de misma profundidad: la llanta aerodinámica de 180 mm ($450) ofrece mayor profundidad para velocidad en llano; la llanta ondulada de 90/95 mm ($350) es más estable y manejable.
Profundidad adyacente: la llanta de 88 mm compatible con tubeless de gancho ($350) es una opción clásica de perfil alto con radios inferior a esta.
Solo para rueda trasera; respete el límite de peso del sistema.
Público objetivo y notas de uso.

Translation missing: es.product.metafields.tradeoffs
- Aero vs Crosswind: The 120mm deep section provides excellent aerodynamic efficiency for straight-line speed, but the deep profile can be challenging in crosswinds. Riders may need to manage handling in gusty conditions, especially at speeds above 30 km/h.
- Aero vs Climbing: At 655g per rim, this carbon rim is lightweight for its Perfil, but when built into a wheelset it still adds significant inertia compared to shallower rims. On steep climbs, the aero benefit is minimal and the Peso penalty becomes noticeable versus a sub-40mm rim.
- Stiffness vs Compliance: The high-modulus carbon layup offers high lateral stiffness for power transfer, but this can translate to a harsh ride on rough roads. The 21.5mm internal width and Tubeless setup allow for lower tire pressures to help compliance, but the rim itself is not designed for comfort.
- Versatility vs Specialization: This rim is specifically designed for time trial and triathlon use, prioritizing aerodynamics over all-round performance. Its Perfil and narrow tire width range (25-28mm) make it less suitable for general road riding, where a shallower rim would be more balanced.

What tubeless setup do I need for this rim?
This rim is tubeless-ready with a hooked bead, so you can run tubeless tires without a tube. Use tubeless-specific tires, sealant, and a valve. For best performance, use a 25-28mm tubeless tire. The rim supports up to 125 psi, but typical road tubeless setups use lower pressure, around 80-100 psi.
What tire sizes are compatible with this rim?
The rim is designed for 700x25c and 700x28c tires. With a 21.5mm internal width, these tire sizes provide an optimized profile for aerodynamics. Using 25mm or 28mm tires is recommended for best performance and comfort.
How much weight does this rim save compared to a standard alloy rim?
This carbon rim weighs approximately 655g, which is about 300-400g lighter than a typical alloy rim of similar depth. Lighter rims reduce rotational mass, improving acceleration and climbing efficiency.
Can I build this rim with custom spokes and hubs?
Yes, this rim can be laced to any compatible hub using standard spokes. The rim has a spoke hole count that can be ordered with various drillings (e.g., 20/24/28). You can choose hubs, spokes, and nipples to suit your weight and riding style. A professional wheel build is recommended.
How do I maintain and inspect the carbon rim?
Regularly inspect the rim for cracks, delamination, or impact damage. Check spoke tension and trueness. Clean with mild soap and water, avoid harsh chemicals. For brake tracks (if applicable), use specific carbon brake pads. If you notice any damage, replace the rim immediately.
