La llanta de carbono aerodinámica profunda Bola de 180 mm: una llanta de contrarreloj/triatlón de perfil UV extremo de 180 mm, 28 mm exterior / 21,5 mm interior, ~815 g, tubeless con gancho, para montajes de rueda trasera aerodinámicos.
El susurro de velocidad más profundo que fabrica Bola: 180 mm de determinación de carbono, construida para recorridos donde el horizonte es plano y el cronómetro es el único juez.
Guía de compra.
Caso de uso: la llanta trasera de máxima aerodinámica solo para recorridos de contrarreloj y triatlón planos y protegidos del viento.
Valoración del recorrido: elígela para eventos planos y con viento neutro; es la opción más sensible a los vientos cruzados y penaliza en las subidas.
Elección de neumáticos: utiliza neumáticos de competición de alta presión de 25-28 mm en el lecho interior estrecho.
Serie de la misma profundidad: la llanta aerodinámica de 120 mm (420 $) es más ligera y manejable; la llanta ondulada de 90/95 mm (350 $) es más estable con ráfagas.
Profundidad adyacente: nada en la gama Bola es más profundo; opta por la llanta de 120 mm para cualquier tipo de viento o terreno ondulado.
Solo rueda trasera; combínala con una delantera más estable y respeta el límite de peso del sistema.
Público objetivo y notas de uso.
Montajes de rueda trasera para contrarreloj/triatlón en recorridos planos y con viento neutro.

Translation missing: es.product.metafields.tradeoffs
- Aero vs Climbing: 180mm Perfil maximizes aerodynamics at 45+ km/h but adds ~815g per rim, making climbing less efficient. Trade-off: ~0.8-1.0 kg for a pair adds rolling Peso that affects accelerations.
- Crosswind vs Aero: Deep 180mm profile is highly aero but noticeably affected by crosswinds, especially over 15-20 km/h side gusts. Riders may need to adjust steering inputs.
- Stiffness vs Compliance: High-modulus carbon offers high lateral stiffness (≥8N/mm) but vertical compliance is reduced; the 21.5mm inner width allows lower pressures for some compliance, but overall it is designed for stiffness over comfort.
- Tire Volume vs Speed: 28mm outer width accommodates up to 32mm tires, giving more volume and grip, but the deep rim aero benefit is maximized with narrower tires (25-28mm). Balanced choice between rolling resistance and aerodynamic drag.

What tire sizes are compatible with the BOLA 180mm rim?
The rim has an inner width of 21.5mm and outer width of 28mm, optimized for 25-32mm tires. For tubeless setups, we recommend 25mm for aero, up to 28mm for comfort, and 32mm for gravel. Avoid narrow tires below 23mm as they may not seat well on the wide rim.
How to set up tubeless tires on this rim?
Use a tubeless-compatible tire and sealant. Apply soapy water to the bead, inflate with a compressor or high-volume pump until the bead seats (typically around 60-80 psi). Then deflate to your desired pressure, between 100-125 psi as rated. Ensure the hooked bead engages properly; the rim meets ETRTO standards.
What is the weight savings compared to a clincher rim?
The rim weighs approximately 815g ±20g itself, which is lightweight for a 180mm deep section. When built into a wheelset with appropriate spokes and hubs, you can save 300-500g compared to a standard alloy aero rim. However, actual savings depend on the build.
Can I build this rim with any hub and spokes?
The rim is drilled for standard J-bend spokes (likely 20/24 holes) and is compatible with most road hubs. We recommend using high-quality butted spokes and a tension of 100-120 kgf for best durability. Consult a professional wheel builder for optimal lacing.
How should I inspect and maintain the rim for safety?
Regularly inspect the rim for cracks, delamination, or impact damage, especially after hard rides. Check spoke tension periodically to ensure evenness. The rim is designed for up to 125kg rider weight; exceeding this could cause failure. Clean with mild soap and avoid abrasive cleaners. If you notice any carbon defects, replace the rim.
