Il cerchio per freno a disco in carbonio ondulato Bola 700C 55/60mm: un cerchio aero ondulato da 55/60mm con larghezza esterna di 28mm e interna di 22mm, disponibile in quattro livelli di peso, per allestimenti aero road e TT.
Un profilo ondulato a sezione profonda che trasforma la turbolenza in un vantaggio: profili da 55 e 60mm che mantengono la velocità senza il nervosismo tipico dei cerchi a sezione profonda con pareti piatte.
Guida all'acquisto.
Livello di peso - Extreme Light ~415g (Leggero): la scelta per salita e accelerazione, pensato per il giorno della gara.
Livello di peso - ~450g (Peso medio): la scelta aero bilanciata per la maggior parte dei ciclisti.
Livello di peso - ~470g (Peso medio): un tocco di durabilità in più per allestimenti più robusti.
Livello di peso - ~515g (Pesante): la scelta resistente agli urti per strade dissestate e ciclisti più pesanti.
Scelta della profondità: scegli 55mm per un compromesso in caso di vento laterale, o 60mm per la velocità sui percorsi pianeggianti.
Serie con stessa profondità: il cerchio ondulato da 90/95mm (350$) è lo specialista per il TT; il cerchio ondulato da 60/65mm da 28mm (330$) è un'opzione ondulata correlata.
Profondità adiacente: il cerchio ondulato da 40/45mm (310$) è più leggero e stabile per le salite.
Pubblico di destinazione e note sull'utilizzo.
Ciclisti su strada aero, specialisti TT e assemblatori di ruote.
Telai stradali per freni a disco; foratura a 24 raggi.
Limite di peso del ciclista 120kg.
Scegli 55mm per il compromesso con vento laterale o 60mm per pura velocità in pianura.
La guida che ti aspetta.
Costruito su 24 raggi, il profilo ondulato scorre magnificamente a ritmo sostenuto, con le sue pareti scolpite che mantengono la ruota stabile in presenza di vento laterale, laddove un cerchio profondo a parete piatta risulterebbe nervoso.
Mantieni la linea che hai scelto.
Spedizione gratuita e una garanzia di 3 anni sui cerchi rendono il cerchio aero ondulato una scelta facile.

Translation missing: it.product.metafields.tradeoffs
- Aero vs Climbing: The 55mm and 60mm depths prioritize aerodynamics over climbing Peso. At 415g, the extreme light option offers a balance, but deeper rims add 50-100g compared to shallower designs.
- Peso vs Durability: Peso options range from 415g to 515g. Heavier rims (515g) offer increased impact resistance and Raggio tension capacity (>300kg), while lighter rims (415g) enhance acceleration but may be less robust.
- Crosswind vs Aero: The wavy profile and 28mm outer width improve crosswind stability compared to traditional deep rims, but at 60mm Altezza, crosswinds still require attention. The 55mm option offers a compromise.
- Tire Volume vs Speed: The 22mm internal width supports 28-32mm tires, increasing volume and comfort. However, wider tires can slightly reduce aerodynamic speed compared to narrower tires, but stability and rolling resistance improve.

What tire sizes are compatible with the Bola 700C carbon rim?
The rim supports tubeless and clincher tires with widths from 28mm to 32mm. The 22mm internal width provides optimal support for 28-32mm tires, ensuring a stable contact patch and reducing pinch flat risk. Recommended tire pressure ranges from 100 to 125 psi. For tubeless setups, use a compatible tubeless valve and sealant. Always check tire manufacturer's recommended pressure range.
How does the tubeless setup work with this rim?
The rim is tubeless-compatible, meaning it has a bead lock design that allows tubeless tires to seat without tubes. For best results, install a tubeless valve, add sealant, and inflate to seat the tire. The rim's internal width of 22mm helps create a tight seal. Ensure the tire bead is properly seated before riding. Use a high-volume pump or compressor to seat the tire initially.
What are the weight options and how do they affect performance?
The rim is available in 415g, 450g, 470g, and 515g (each ±15g). The 415g option is 'Extreme Light' for climbing and acceleration, but may be less durable. Heavier options like 515g offer increased strength and impact resistance. The weight difference affects rotational inertia and overall bike weight. Choose based on your priority between weight savings and durability.
Can I customize the rim for my build?
Yes, the rim offers custom options. It features a standard 6.5mm valve hole, but custom drillings are available upon request. The 24-spoke configuration is designed for disc brakes, and you can choose spoke count based on your weight and riding style. Rim depth options include 55mm and 60mm, allowing you to tailor aerodynamics. Custom decals and finishes might also be available.
How do I maintain and inspect this carbon rim?
Regularly inspect the rim for cracks, delamination, or impact damage, especially after hard rides. Clean with mild soap and water; avoid harsh chemicals. Check spoke tension regularly (max 300kg). Ensure brake surfaces (if any) are clean, but since this is disc brake, focus on the rim bed. For tubeless, periodically check sealant levels. Also, torque all bolts to manufacturer specs.
