Cerchio da strada in carbonio da 60mm con profilo a V certificato UCI, larghezze 30/24mm e canale tubeless-ready per gare su strada competitive e endurance.
Aero pronta gara, prezzo diretto di fabbrica
Il cerchio in carbonio BOLA da 60mm UCI mantiene la velocità in pianura, in discesa e negli sprint. Il suo profilo a V da 60mm, la larghezza esterna di 30mm e quella interna di 24mm ottimizzano il flusso d'aria supportando i moderni pneumatici tubeless da strada da 27–42mm.
Guida all'acquisto.
Classe di peso - Standard ~515g: la scelta per i ciclisti più pesanti e per le giornate di gara più dure che richiedono un margine di resistenza agli impatti.
Classe di peso - Superlight ~490g: l'opzione versatile, ottimo risparmio di peso senza rinunciare alla durata.
Classe di peso - Ultralight ~460g: per gli scalatori che desiderano comunque prestazioni aerodinamiche in pianura; da scegliere solo se si guida con fluidità.
Classe di peso - Extreme Light ~440g: il minimo assoluto per i corridori leggeri su strade lisce; il margine più sottile.
Peso del ciclista - rated elevato, ma le versioni più leggere richiedono ciclisti più leggeri; rispettare il limite.
Altre altezze - questo è il profilo più alto della gamma stradale Bola; scegliere un cerchio più basso per terreni ondulati dove un profilo alto può risultare svantaggioso.
Pubblico di destinazione e note d'uso.
Ciclisti su strada in gare UCI, triatleti su percorsi ondulati e ciclisti endurance che desiderano un cerchio aero tuttofare.
Non raccomandato per salite ripide (scegliere un cerchio da 30–40mm), fuoristrada o utilizzo gravel.
L'esperienza di guida che ti aspetta.
Aggancia i pedali, arriva sulla linea di partenza e lascia che quel profilo a V tagli il vento mentre tieni il manubrio saldo: il canale largo sostiene al meglio i tuoi pneumatici, la struttura rigida risponde a ogni scatto come se la strada fosse complice. Regolare UCI e ineccepibile, mantiene la velocità sui percorsi ondulati come una promessa silenziosa. Tre anni di garanzia e spedizione gratuita significano che l'unica cosa che resta da fare è gareggiare.
Specifications
- Material: Unidirectional carbon
- Rim depth: 60mm
- External width: 30mm
- Internal width: 24mm
- Size: 700C
- Profile: V-shaped
- Weight Tier: Light: ~440g, Heavy: ~515g
- Max Tire Pressure: 90
Trade-offs & Considerations
- Aero vs Climbing: The 60mm depth and V-shape profile reduce drag, but the weight (440-515g) is higher than typical climbing rims. This makes it less ideal for steep ascents, though the weight tier can be chosen for lighter builds.
- Stiffness vs Compliance: The unidirectional carbon construction provides high stiffness for power transfer, but the 24mm internal width allows wider tires at lower pressures, offering some compliance. The trade-off is between direct response and ride comfort.
- Tire Volume vs Speed: The 24mm internal width supports 25-32mm tires, increasing volume and comfort, but wider tires can slightly reduce aerodynamic efficiency. However, the rim's external width (30mm) is designed to smooth airflow with wider tires.
- Weight vs Durability: Rim weight ranges from 440g to 515g. Lighter builds (440g) favor climbing and acceleration, while heavier builds (515g) offer more robustness for heavy riders (up to 125kg) and long-term durability.
Performance Test Data
- Fatigue Test: 750,000 cycles @640N (ISO 4210-7 Annex A, informative only)
- Impact Resistance: >40J (ISO 4210-7 reference)
- Flatness: <0.25mm (internal QC)
- Roundness: <0.3mm (internal QC)
- Max Spoke Tension: >300kg (internal QC)
- Ultimate Strength: >100kg (internal QC)
- Dynamic Equilibrium: <3g (internal QC)
- Radial Stiffness: 90–110 N/mm (internal lab)
- Lateral Stiffness: ≥8N/mm
- Max System Weight: 125
Recommended Use Cases
- Sprinting / Criterium: Excellent. The 60mm depth and stiff construction provide aerodynamic efficiency and responsive acceleration for sprint finishes.
- Triathlon / TT: Excellent. The aerodynamic profile reduces drag at high speeds, ideal for time trials and triathlons.
- Road Racing: Excellent. UCI certified and designed for competitive road racing, balancing aero and stiffness.
- Gran Fondo / Endurance: Good. The tubeless compatibility and wider internal width (24mm) allow lower pressures for comfort over long distances, but the depth may be less forgiving on climbs.
- Climbing / Hill Repeats: Not recommended. While the rim is light for its depth (440g minimum), the 60mm profile is not ideal for steep climbs where low weight is prioritized.
- Not Recommended For: Off-road, gravel, or rough terrain due to aerodynamic depth and road-specific design.
Compatibility
- Frame Compatibility: Standard 700C frames and hubs
- Tire Type: Tubeless-ready, also compatible with clincher tires
- Tire Width Range: 27-42mm
- Brake Standard: Rim brake
- Drivetrain: Compatible with standard road drivetrains (Shimano, SRAM, Campagnolo)
- Rotor Standard: N/A (rim brake only)

FAQ
How do I set up this rim tubeless?
Ensure you use tubeless-specific tape and valves (Presta). Mount tubeless tires rated for 25-32mm width. Use sealant per manufacturer's recommendation. Inflate to the recommended pressure range of 100-125 psi, but adjust based on rider weight and conditions. The rim is designed to be airtight and easy to set up.
What tire sizes are compatible?
This rim is compatible with tubeless road tires from 25mm to 32mm width. The 24mm internal width supports modern wider tires for improved grip and comfort. It also works with clincher tires if you prefer.
How much weight can I save compared to a standard aluminum rim?
The BOLA 60mm carbon rim weighs approximately 440-515g (depending on tier). Typical aluminum rims of similar depth weigh 500-600g, so you can save up to 100g per rim. This reduces rotating mass and improves acceleration.
Can I customize the spoke and valve hole drilling?
Yes, the rim offers build customization. You can specify spoke hole drilling and valve hole size to match your hubs and valve types. Consult the manufacturer for custom requests and compatibility checks.
How do I maintain and inspect the rim for safety?
Regularly inspect the rim surface for cracks, delamination, or impact damage, especially after heavy braking or impacts. Check spoke tension and ensure spoke nipples are secure. Clean the braking surface with isopropyl alcohol to maintain brake performance. The rim is rated for riders up to 125kg, and pressure should be within 100-125 psi.
