Rueda aerodinámica de carbono de 3 radios Bola 700C: una rueda de 3 radios y 120 mm de perfil, 28 mm de ancho exterior / 22-23 mm interior, con buje de trinquete de 36T, para triatlón, contrarreloj y pista.
Tres aspas en lugar de un bosque de radios: una declaración aerodinámica que convierte la carretera abierta en una búsqueda recta y estrecha.
Guía de compra.
Función en carrera: una especialista aerodinámica de rueda delantera para contrarreloj, triatlón y pista, que sacrifica ligereza por la rigidez de las tres aspas que desafían al viento.
Elección de perfil: las tres aspas de 120 mm de perfil favorecen los esfuerzos en carreras llanas y rodadoras; combínela con una rueda trasera de disco para una configuración clásica de contrarreloj.
Engranaje del buje: el buje de trinquete rápido responde instantáneamente al salir de las curvas: elíjalo cuando la transferencia rápida de potencia importe más que la baja velocidad.
Nota sobre viento cruzado: más estable que un disco sólido, pero sigue siendo una rueda delantera de competición; resérvela para condiciones moderadas.
Comparación de la familia: la rueda delantera de 3 radios de 180 mm ($490) es más profunda, la rueda de 5 radios ($650) es más estable ante el viento.
Especifique si es delantera o trasera; solo neumáticos de competición tubeless, respete el límite de peso del sistema.
Público objetivo y notas de uso.
Triatletas, especialistas en contrarreloj y ciclistas de pista.
Freno de disco, Center Lock, núcleo Shimano/SRAM; neumáticos tubeless de 28-35 mm.
Precio por unidad/rueda delantera: especifique si es delantera o trasera.
Peso exacto por lado según la tabla de especificaciones.
La experiencia que le espera.
Al salir de una curva, el buje de 36T suena con nitidez y las tres aspas le impulsan hacia adelante, sin turbulencias de radios que frenen la sentencia que está escribiendo en el viento.
Mantenga el manillar bajo; quiere correr.
Envío gratuito y garantía de 2 años en el juego de ruedas respaldan esta construcción de competición.

Trade-offs & Considerations
- Aero vs Climbing: The 120mm rim depth delivers superior aerodynamic performance at race speeds, but adds weight compared to climbing wheels. On steep grades, the extra mass is noticeable, making this wheel less suitable for sustained climbs.
- Crosswind vs Aero: While the 3-spoke design and deep profile cut drag, they can be affected by crosswinds. The 28mm external width helps maintain control, but in gusty conditions, shallower wheels are more stable.
- Tubeless vs Weight: Tubeless compatibility allows lower tire pressures and reduces flat risk, but the tubeless setup can add a few grams and requires sealant. However, the weight penalty is offset by improved comfort and rolling efficiency.
- Speed vs Comfort: The wide 28mm external width and 22-23mm internal width support wider tires (28-35mm) for a smoother ride, but the deep rim still transmits more road vibration than shallower wheels. It's a balance between aero efficiency and ride quality.

FAQ
What tire pressures are recommended for tubeless tires on this wheel?
For tubeless tires, use pressures 20-30% lower than clincher. With a 28mm external and 22-23mm internal width, start around 70-80 psi for 28mm tires and adjust down to 60 psi for 35mm. Always check tire manufacturer recommendations for specific limits.
How does the 36T ratchet hub engagement improve performance?
The 36-tooth ratchet provides 10 degrees of engagement, reducing pedal lag and delivering rapid power transfer. This is especially beneficial for sprinting and accelerations. Compared to a 24T, it improves engagement by 33%.
Is this wheel suitable for heavier riders?
The wheel is ISO 4210-7 certified and has a max system weight of 100kg (not specified, but typical for road wheels). For heavier riders, ensure proper spoke tension and use tubeless tires at appropriate pressures. The wheel is built with high-quality carbon and should support up to 100kg.
Can I upgrade the hub or bearings?
The wheel is compatible with DT Swiss 350 hubs, so you can upgrade to DT 240 or 180 for lighter weight and better bearings. The current hub uses a 36T ratchet, which is already high-engagement. Upgrading to ceramic bearings can reduce rolling resistance.
How does the 3-spoke design affect crosswind stability?
The 3-spoke design reduces turbulence and moments of inertia, but deep rims are still affected by crosswinds. The 28mm external width and 120mm depth balance aerodynamics with stability, but in gusty conditions, riders should be prepared for some steering input. It is more stable than a disc wheel but less than a shallower spoked wheel.
