La llanta de carretera de carbono Bola 700C de 50 mm: una llanta para disco de 50 mm con forma en U y pestaña, 34 mm exterior / 28 mm interior, 370-445 g, para montajes de carretera aerodinámicos y all-road de neumáticos anchos.
Una sección aerodinámica de 50 mm con una base ancha y moderna, diseñada para el ciclista que se niega a elegir entre la velocidad y la comodidad de un neumático de 32 mm.
Guía de compra.
Nivel de peso - ligero ~370 g (Ultraligero): para ciclistas de aero-all-road que buscan escalar y acelerar, deseando la comodidad de neumáticos anchos.
Nivel de peso - superior ~445 g (Ligero/Peso medio): para carreteras más irregulares y ciclistas de mayor peso, añadiendo un margen contra impactos.
Ancho interno - 28 mm: 30-40 mm a ~50-75 PSI para aero-all-road, 40-45 mm a ~40-60 PSI para superficies mixtas irregulares.
Serie de misma profundidad: la llanta UV de 50 mm y 23 mm ($310) es la opción de velocidad con base estrecha; la llanta asimétrica de 50 mm y 36 mm ($320) es aún más ancha.
Profundidad adyacente: la llanta de 45 mm y 34/28 mm ($310) es más ligera y más estable ante el viento cruzado.
Solo para montajes con disco; respete el límite de peso del sistema.
Público objetivo y notas de uso.
Corredores de aero-all-road, ciclistas de gran fondo y montadores de ruedas.
Solo para cuadros con frenos de disco; perforación 20/20, perforación personalizable. Límite de peso del ciclista de 120 kg.
Utilice cinta de llanta de 30 mm para tubeless.
La experiencia que le espera.
Montada con un neumático tubeless de 32 mm, se siente rápida en llano y, a la vez, notablemente relajada sobre superficies all-road irregulares: lo suficientemente ancha para brindarle comodidad, lo suficientemente profunda para impulsarle.
Llegará más rápido y menos agotado.
Envío gratuito y una garantía de 3 años en la llanta respaldan el montaje.

- Material: carbon fiber
- Perfil: 50mm
- Ancho exterior: 34mm
- Ancho interior: 28mm
- Tamaño: 700c
- Profile: U-shaped
- Peso Tier: 370-445g
- PSI máximo: 90
Translation missing: es.product.metafields.tradeoffs
- Aero vs Climbing: The 50mm profile and 34mm outer width reduce drag but add approximately 50-100g over a 45mm rim. Riders prioritizing low Peso for climbs may prefer lighter shallower options.
- Stiffness vs Compliance: High-modulus carbon construction ensures lateral stiffness (≥8N/mm) for sprinting, but the U-shaped hooked profile and 28mm inner width provide some vertical compliance to absorb road buzz without sacrificing power transfer.
- Tire Volume vs Speed: The 28mm internal width supports 25-32mm tires, optimized for 28mm; wider tires increase comfort and grip but slightly increase rolling resistance and aerodynamic drag at higher speeds.
- Peso vs Durability: Available layups range from 370g to 445g; lighter options save ~75g per rim but may have slightly reduced impact resistance, while heavier options offer more robust fatigue life (verified >300kg compressive strength).

- Sprinting / Criterium: Good. Stiffness and aero help in sprints, but Peso may be a factor for punchy climbs.
- Triathlon / TT: Excellent. 50mm Perfil provides significant aero advantage at sustained speeds.
- Road Racing: Good. Balanced aero and stiffness, suitable for race days.
- Gran Fondo / Endurance: Good. Wide tire compatibility and Tubeless ready enhance comfort on long rides.
- Climbing / Hill Repeats: Not recommended. Peso (370-445g) is heavier than dedicated climbing rims; shallower profiles are lighter.
- Not Recommended For: Not recommended for extreme off-road or heavy gravel; designed for road and light gravel.

What tire sizes are compatible with this rim?
The 28mm inner width supports tires from 25-32mm, optimized for 28mm. Modern wider road tires (28-30mm) pair well with the 34mm external width for optimal aero and comfort. Clincher and tubeless tires are both compatible.
How do I set up tubeless on this rim?
Use 30mm rim tape specifically for tubeless to ensure a reliable seal. Install the tire, add sealant, and inflate to seating pressure. The rim's hooked profile and 28mm inner width provide secure bead retention. Maximum pressure is 125 psi, but typical road pressures are 80-100 psi for 28mm tires.
What is the weight and how does it affect performance?
The rim weight ranges from 370g to 445g depending on the layup grade. Lighter rims reduce rotational weight, improving acceleration and climbing, while heavier options offer more robust durability and impact resistance. Choose based on your priority: climbing vs all-round performance.
Can I customize the rim for my build?
Yes, valve hole size (default 6.5mm), spoke hole diameter (default 4.5mm), and nipple angle (front 7°, rear 5° or 7°) can be adjusted. This allows wheelbuilders and OEMs to match specific hub and spoke requirements. Custom layup options are also available for weight vs strength trade-offs.
What maintenance is required for carbon rims?
Regularly inspect the rim for cracks, delamination, or impact damage. Clean with mild soap and water; avoid harsh chemicals. Check spoke tension periodically. Avoid overheating (e.g., prolonged braking) as it can degrade the resin. The rim's fatigue-tested construction (750,000 cycles) ensures durability under normal use.
