Cerchio 700C in carbonio per Gravel & Ciclocross — 35mm Tubeless-Ready
Cerchio 700C in carbonio per Gravel & Ciclocross — 35mm Tubeless-Ready
Impossibile caricare la disponibilità di ritiro
Il cerchio Bola 700C in carbonio a profilo a V per gravel/ciclocross: un cerchio per freni a disco da 35 mm di profondità e 30 mm di larghezza (330-400 g) progettato per gravel e CX.
Stabile sui terreni accidentati: il profilo a V da 35 mm offre una forma costante nei settori gravel esposti e con vento laterale, mentre la larghezza esterna da 30 mm supporta i moderni pneumatici larghi.
Guida all'acquisto.
Fascia di peso - Ultralight ~330g: la versione per gare gravel e CX per ciclisti più leggeri che desiderano velocità di accelerazione.
Fascia di peso - Superlight ~360g: il giusto equilibrio tra gara e allenamento.
Fascia di peso - Standard ~400g: la versione ad alta resistenza per gravel impegnativo e lunghi chilometraggi a pieno carico.
Larghezza interna - 24 mm con gancio (hooked):
una piattaforma più ampia da 27-42c: scegliila per la compatibilità con camera d'aria e una sensazione di maggiore velocità.
Larghezza interna - 25 mm senza gancio (hookless): una piattaforma a bassa pressione più ampia da 29-44c: scegliila per un gravel confortevole e il ciclocross.
Della stessa linea: il modello specifico gravel/CX da 35 mm: il cerchio gravel da 40 mm ($310) aggiunge aerodinamicità, il cerchio da 30 mm offre maggiore comfort.
Omologato per un peso del sistema di 105 kg.
Target e note sull'utilizzo.
Gare gravel, ciclocross, bikepacking e gran fondo.
Peso massimo del sistema 105 kg; non adatto a downhill o percorsi trail pesanti.
Solo per freni a disco (Center Lock o 6 fori).
L'esperienza di guida che ti aspetta.
Affronta una curva nel ciclocross e senti come il profilo a V annulla il vento laterale: più stabile di un cerchio alto, più largo di un cerchio da corsa, costruito per il gravel esposto. Il clincher tubeless alloggia perfettamente gli pneumatici larghi e mantiene la traiettoria durante le lunghe gare. Scegli la larghezza interna e la stratificazione; la garanzia sul cerchio di 3 anni ti offre tutta la protezione necessaria.

Trade-offs & Considerations
- Aero vs Climbing: The 35mm depth offers a good balance between aerodynamic efficiency and low weight (330-400g). On steep climbs, the modest depth minimizes rotational weight, while still providing some aero benefit on flats.
- Tire Volume vs Speed: With internal widths of 24mm and 25mm, you can run tires from 33c to 50c. Wider tires improve comfort and grip, but may reduce aerodynamics; however, the 30mm outer width helps maintain a smooth transition.
- Stiffness vs Compliance: The carbon laminate is engineered to be laterally stiff (≥8N/mm) for precise handling, while the 35mm profile allows some vertical flex for comfort over rough gravel. It's a trade-off between responsiveness and ride quality.
- Crosswind vs Aero: The 35mm depth and 30mm outer width make the rim stable in crosswinds, reducing the need for constant correction. It's a compromise between aero gains and handling confidence, especially on exposed sections.

FAQ
How do I set up this rim tubeless?
Use a tubeless valve (6.5mm hole) and tubeless tire sealant. Mount the tire, inflate to seat the bead, then add sealant. Recommended pressure is 30-50 psi depending on tire width and rider weight.
What tire sizes are compatible with the 24mm internal width?
The 24mm internal width is ideal for 33c-42c tires. For 40c-50c, choose the 25mm internal width. Always check tire manufacturer's recommended rim width range.
How much weight can I save with these rims?
Each rim weighs 330-400g, saving 100-200g per rim compared to alloy versions. For a wheelset, you could save over 400g, improving acceleration and climbing.
Can I build a custom wheelset with these rims?
Yes, the rims are designed for custom builds. They are disc-brake compatible and work with center-lock or 6-bolt hubs. Spoke tension is certified above 280kgf, ensuring reliable builds.
How do I maintain and inspect carbon rims?
Regularly check for cracks, delamination, or impact damage. Clean with mild soap and check spoke tension. Avoid excessive braking heat, though these rims are rated for disc brakes. Always follow torque specs when mounting tires.
