El Bola CE 40R es un juego de ruedas de disco de carbono UD T800 de 40 mm, montado sobre un buje DT Swiss OEM de 36T con radios de carbono aerodinámicos, con un peso de 1270 g, diseñado para ciclismo de carretera y gravel orientado a la escalada.
La cuchilla escaladora: 40 mm, 1270 g, sistema de trinquetes DT Swiss. El Bola CE 40R combina una llanta de carbono mate T800 de 40 mm (28-30 mm de ancho externo, 21-24 mm de interno) con un buje de trinquetes DT Swiss OEM de 36T y radios de carbono aerodinámicos: un modelo polivalente orientado a la escalada, lo suficientemente bajo para ascender y lo suficientemente profundo para ser aerodinámico.
Guía de compra.
Ancho interno - 21 mm: 28c a 70-85 PSI para asfalto liso.
Ancho interno - 24 mm: 32c a 50-60 PSI para uso mixto (all-road).
Peso máximo del ciclista: clasificado hasta 105 kg, el más bajo de la serie CE; los ciclistas más pesados deberían considerar el modelo CE 45R.
Serie de la misma profundidad: el EXP 40R (~999 $) mantiene los radios de acero CX-Ray y el EXT 40R (~1111 $) incorpora rodamientos cerámicos más ligeros; el CE 40R combina un buje de trinquetes DT con radios de carbono aerodinámicos.
Profundidad adyacente: el CE 45R, de mayor perfil, aporta más aerodinámica; elija el 40R para escalar y el 45R para obtener velocidad.
Público objetivo y notas de uso.
Cuadros de carretera y gravel con frenos de disco, eje pasante de 12x100/12x142.
Peso máximo del sistema 105 kg (el más bajo de la serie CE); los ciclistas más pesados deben considerar el modelo CE 45R (110 kg).
No apto para uso extremo fuera de pista.
La experiencia que le espera.
La primera subida lo confirma: cada tramo empinado se supera sin esa carga que recuerda, y la profundidad de la llanta nunca se siente como un peso. En el descenso mantiene la trayectoria frente a las ráfagas; los trinquetes suenan con precisión a la salida de cada horquilla. Envío gratuito y una garantía de 3 años para la llanta y 2 años para el juego de ruedas hacen que las subidas sean más agradables.
Specifications

Trade-offs & Considerations
- Aero vs Climbing: This 40mm depth balances aerodynamic efficiency with lightweight 1270g, favoring climbing over deep-section aero, but still offering decent aero for flat sections.
- Stiffness vs Compliance: The T800 carbon and foil carbon spokes provide high stiffness for power transfer, while the wide rim profile allows lower tire pressures for added compliance on rough roads.
- Weight vs Durability: At 1270g, the wheelset is lightweight but relies on durable DT Swiss hub and carbon construction; however, it may be less robust than heavier alloy wheelsets for extreme abuse.
- Crosswind vs Aero: The 40mm depth reduces crosswind sensitivity compared to 50mm+ rims, making it more controllable in gusty conditions, but it sacrifices some aerodynamic drag reduction.

FAQ
What riding scenarios is this wheelset best suited for?
This wheelset is designed for mixed road and gravel riding, excelling in climbing, endurance, and daily training. Its 40mm depth and lightweight 1270g make it versatile for varied terrain, and the wide rim supports larger tires for comfort on rough roads.
How does the weight affect stiffness and responsiveness?
The lightweight construction (1270g) reduces rotational mass, improving acceleration and climbing efficiency. The T800 carbon rims and foil carbon spokes provide high lateral stiffness, ensuring responsive power transfer without excessive weight penalty.
What is the hub engagement and how does it impact performance?
The DT Swiss OEM hub features a 36-tooth ratchet, providing fast and reliable engagement on technical sections. This quick engagement enhances acceleration out of corners, making it ideal for racing and group rides.
What tire pressures are recommended for tubeless setup?
For tubeless setups, pressures typically range from 60-80 psi for 28-32c tires, depending on rider weight and terrain. The wide rim allows lower pressures for better traction and comfort without compromising rolling resistance.
What industry hot topics does this wheelset address?
This wheelset addresses bearing longevity with DT Swiss steel bearings known for reliability, and spoke tension maintained by the straight-pull foil carbon spokes. It also meets ISO 4210-7 certification for safety and REACH compliance for material standards, addressing impact damage and crosswind handling concerns.
