Cerchio Bola 700C 180mm Deep Aero in carbonio Tubeless | 28mm di larghezza TT Triathlon
Impossibile caricare la disponibilità di ritiro
Cerchio aero in carbonio Bola 180mm deep - un cerchio estremo da 180mm a profilo UV per TT/triathlon, 28mm esterno / 21,5mm interno, ~815g, hooked tubeless, per allestimenti aero su ruota posteriore.
Il sussurro di velocità più profondo di Bola - 180mm di fibra di carbonio, costruito per i percorsi in cui l'orizzonte è piatto e il cronometro è l'unico giudice.
Guida all'acquisto.
Caso d'uso: il cerchio posteriore a massima aerodinamicità esclusivamente per percorsi TT e triathlon piatti e riparati dal vento.
Valutazione del percorso: sceglilo per eventi piatti e con vento neutro; è l'opzione più sensibile al vento laterale e penalizza le salite.
Scelta dello pneumatico: utilizza pneumatici da gara ad alta pressione da 25-28mm sul canale interno stretto.
Serie stessa profondità: il cerchio aero da 120mm ($420) è più leggero e gestibile; il cerchio wave da 90/95mm ($350) è più stabile durante le raffiche.
Profondità adiacente: nulla nella gamma Bola è più profondo - passa al cerchio da 120mm per qualsiasi condizione di vento o terreno ondulato.
Solo per ruota posteriore; abbinalo a un'anteriore più stabile e rispetta il limite di peso del sistema.

Translation missing: it.product.metafields.tradeoffs
- Aero vs Climbing: 180mm Altezza maximizes aerodynamics at 45+ km/h but adds ~815g per rim, making climbing less efficient. Trade-off: ~0.8-1.0 kg for a pair adds rolling Peso that affects accelerations.
- Crosswind vs Aero: Deep 180mm profile is highly aero but noticeably affected by crosswinds, especially over 15-20 km/h side gusts. Riders may need to adjust steering inputs.
- Stiffness vs Compliance: High-modulus carbon offers high lateral stiffness (≥8N/mm) but vertical compliance is reduced; the 21.5mm inner width allows lower pressures for some compliance, but overall it is designed for stiffness over comfort.
- Tire Volume vs Speed: 28mm outer width accommodates up to 32mm tires, giving more volume and grip, but the deep rim aero benefit is maximized with narrower tires (25-28mm). Balanced choice between rolling resistance and aerodynamic drag.

What tire sizes are compatible with the BOLA 180mm rim?
The rim has an inner width of 21.5mm and outer width of 28mm, optimized for 25-32mm tires. For tubeless setups, we recommend 25mm for aero, up to 28mm for comfort, and 32mm for gravel. Avoid narrow tires below 23mm as they may not seat well on the wide rim.
How to set up tubeless tires on this rim?
Use a tubeless-compatible tire and sealant. Apply soapy water to the bead, inflate with a compressor or high-volume pump until the bead seats (typically around 60-80 psi). Then deflate to your desired pressure, between 100-125 psi as rated. Ensure the hooked bead engages properly; the rim meets ETRTO standards.
What is the weight savings compared to a clincher rim?
The rim weighs approximately 815g ±20g itself, which is lightweight for a 180mm deep section. When built into a wheelset with appropriate spokes and hubs, you can save 300-500g compared to a standard alloy aero rim. However, actual savings depend on the build.
Can I build this rim with any hub and spokes?
The rim is drilled for standard J-bend spokes (likely 20/24 holes) and is compatible with most road hubs. We recommend using high-quality butted spokes and a tension of 100-120 kgf for best durability. Consult a professional wheel builder for optimal lacing.
How should I inspect and maintain the rim for safety?
Regularly inspect the rim for cracks, delamination, or impact damage, especially after hard rides. Check spoke tension periodically to ensure evenness. The rim is designed for up to 125kg rider weight; exceeding this could cause failure. Clean with mild soap and avoid abrasive cleaners. If you notice any carbon defects, replace the rim.
