Cerchio da corsa in carbonio Bola 700C da 60mm: un cerchio a profilo a U da 60mm, tubeless-ready con canale interno da 23mm per freni a disco, disponibile nelle configurazioni Standard/Superlight/Ultralight, ideale per build aero road e crono.
Ben 60mm di carbonio aerodinamico: profondo, determinato e pensato appositamente per il ciclista per cui la pianura è una tela e il vento laterale un degno avversario.
Guida all'acquisto.
Livello di peso - Standard (Pesante/Durevole): per i ciclisti che privilegiano la stabilità e la resistenza agli impatti rispetto alla velocità in salita.
Livello di peso - Superlight (Peso medio): la scelta aerodinamica tuttofare, più leggera della Standard ma comunque resistente.
Livello di peso - Ultralight (Peso medio): la scelta del corridore, che riduce la massa per le salite pur mantenendo una configurazione aerodinamica.
Larghezza interna - 23mm: pneumatici da strada da 28-32mm a circa 70-95 PSI per bici da corsa aero e da crono.
Serie con stessa profondità: il cerchio tubeless da 60mm e 28mm ($310) offre una piattaforma per pneumatici più larga; il cerchio da 60mm UCI da 30mm ($310) è un'opzione aerodinamica orientata all'UCI.
Profondità adiacente: il cerchio a U da 50mm e 23mm ($310) è più gestibile con vento laterale; il cerchio da 65mm per triathlon ($340) offre una maggiore profondità per le crono.
Solo per build con freni a disco; rispettare il limite di peso del sistema.
Pubblico di riferimento e note di utilizzo.
corridori su strada aero, ciclisti crono e assemblatori di ruote.
Solo telai da strada per freni a disco (nessuna pista frenante per cerchio); foratura 20/20, angoli dei nippli personalizzati (anteriore 7, posteriore 5/7).

Translation missing: it.product.metafields.tradeoffs
- Aero vs Climbing: The 60mm Altezza gives a significant aerodynamic advantage at speed, but adds Peso compared to shallower rims. For climbing, this rim is heavier than a 30-40mm option, which could slow you on steep gradients. However, the availability of light layups (Superlight/Ultralight) helps mitigate this.
- Crosswind vs Aero: Deep 60mm rims can be more sensitive to crosswinds. The 23mm inner width and 34mm max outer width are designed to work with wider tires (28mm+), which can improve stability. The aerodynamic shaping reduces drag, but in gusty conditions, riders may need to be cautious.
- Tire Volume vs Speed: The 23mm inner width supports wider tires (25-32mm), offering more comfort and lower rolling resistance at appropriate pressures. While wider tires can slightly reduce top-end speed compared to narrow ones, the overall efficiency and ride quality are improved, especially on rough roads.
- Peso vs Durability: The rim is available in Standard, Superlight, and Ultralight layups. Standard offers maximum durability, while Superlight and Ultralight reduce Peso for racing but may be more prone to impact damage. The rim's high compressive strength (>300kg) and torsion resistance ensure durability across grades.

Translation missing: it.product.metafields.usecases
- Sprinting / Criterium: Good. The deep section provides aero benefit for accelerations and sprint speeds.
- Triathlon / TT: Excellent. The 60mm Altezza is ideal for sustained high-speed efforts, reducing drag.
- Road Racing: Excellent. Aero efficiency and Tubeless readiness suit competitive road racing.
- Gran Fondo / Endurance: Good. Wide tire support and Tubeless setup add comfort for long rides.
- Climbing / Hill Repeats: Not recommended. The deep section is heavy for steep climbs; a shallower rim would be more efficient.
- Not Recommended For: Off-road or gravel riding due to its deep profile and disc-Freno-only design; also not for rim Freno bikes.

- Frame Compatibility: Disc Freno road bikes with 700c (ISO 622mm) wheels. Compatible with standard road hubs.
- Tire Type: Clincher and Tubeless tires. Tubeless-ready, Senza uncino-compatible.
- Tire Width Range: 27-40mm (recommended).
- Freno Standard: Disc Freno only (no rim Freno track).
- Drivetrain: Compatible with standard road drivetrains (Shimano, SRAM, Campagnolo).
- Rotore Standard: N/D (rim only).

How do I set up this rim tubeless?
To set up tubeless, use 25mm rim tape and 6.5mm valves. The rim is hookless-compatible, so ensure tires are tubeless-ready. Install the tire, inflate to seat the bead, then apply sealant. Recommended tire pressure is 100-125 psi for clinchers; for tubeless, lower pressures are common, depending on tire width and rider preference.
What tire sizes are compatible?
The rim is designed for 700c (ISO 622mm) tires. Recommended tire widths are 25-32mm. The 23mm inner width provides stable support for wider tires, improving comfort and rolling resistance. Use tubeless or clincher tires; the rim is hookless-compatible.
How much weight can I save compared to standard rims?
The rim is available in three layups: Standard, Superlight, and Ultralight. Weight savings depend on the chosen grade. For example, Superlight and Ultralight options reduce weight for racing, while Standard prioritizes durability. Specific weights are not published, but Ultralight typically saves 100-150g over Standard.
Can I customize the rim for my build?
Yes, the rim is customizable for wheelbuilders. You can specify spoke hole count, valve hole (default 6.5mm), spoke hole diameter (default 4.5mm), assembly hole diameter (default 7.5mm), and nipple angles (front 7°, rear 5° or 7°). This allows for bespoke wheel builds and OEM branding.
What maintenance does the rim require?
Regular inspection for impact damage, especially after hard rides. Check spoke tension and rim trueness periodically. The rim has a three-year warranty; ensure proper installation and torque on components. Avoid exceeding the maximum pressure rating (125 psi for clinchers) and rider weight limit (120kg).
