    Set di ruote Bola CLA 40R 700C Road in carbonio per freni a disco tubeless: un set aerodinamico da 40 mm leggero e versatile per strada e gravel, realizzato in carbonio Toray T700/T800.

    Pedala più velocemente su superfici miste con un set di ruote progettato per bilanciare aerodinamica, durata e praticità quotidiana. Le Bola CLA 40R abbinano un cerchio da 40 mm con struttura tubeless-ready e un profilo leggero di circa 1370g: un upgrade in carbonio affidabile senza costi eccessivi.

    Guida all'acquisto.

    Larghezza interna - 21mm: utilizza uno pneumatico da 28mm a 75-90 PSI per asfalto liscio.

    Larghezza interna - 24mm: monta uno pneumatico da 30-32mm a 65-80 PSI per strade miste.

    Larghezza interna - 26mm: utilizza uno pneumatico da 35-45mm a 50-65 PSI su asfalto ruvido e sterrato.

    Peso massimo del ciclista: classificato per un peso del sistema di 105kg: verifica il peso del ciclista e dell'attrezzatura prima di ordinare.

    Serie con profondità analoga: tra i modelli stradali a profilo più basso, le ELT 40R aggiungono un mozzo in ceramica a $579 e le ULT 40R aggiungono raggi CX-Ray a $698: scegli queste CLA come il modello tuttofare dal miglior rapporto qualità-prezzo.

    Profondità adiacente: le CLA 50R aggiungono aerodinamicità per percorsi pianeggianti, mentre queste 40R rimangono più leggere e stabili con raffiche di vento: la scelta ideale per i ciclisti che affrontano salite.

    Target di riferimento e note sull'utilizzo.

    Per ciclisti su strada e gravel che passano dall'alluminio, per chi si allena e per gli scalatori.

    Richiede perni passanti 12x100/12x142 e freni a disco.

    Peso massimo del sistema 105kg.

    Tubeless-ready; compatibile con copertoncino.

    L'esperienza di guida che ti attende.

    Un percorso con colline ondulate sembra quasi facile: il cerchio a profilo basso ti accompagna sui dossi senza risentire del vento laterale, e la vivacità della coppia rende ogni spinta in salita un vero piacere. Le pressioni tubeless intorno ai 60psi assorbono completamente le vibrazioni della strada. Spedizione gratuita, IVA inclusa e una garanzia di 3 anni sui cerchi / 2 anni sul set di ruote con copertura del 30% per sostituzione in caso di incidente significano che puoi effettuare l'upgrade oggi e sentirne i benefici alla prossima uscita.

    Trade-offs & Considerations
    • Aero vs Climbing: The 40mm rim depth provides a good aero balance, while the 1360g weight keeps it light enough for climbing. This makes it a versatile choice for hilly races and flat time trials.
    • Stiffness vs Compliance: The carbon layup offers high stiffness for efficient power transfer, but the tubeless setup allows pressures as low as 60psi to enhance ride comfort without losing much speed.
    • Tire Volume vs Speed: You can run tires from 25mm to 45mm wide, but narrower tires (25-28mm) will yield lower rolling resistance, while wider (35-40mm) provide more grip and compliance for gravel.
    • Price vs Grade: This wheelset retails for significantly less than premium carbon options (around $1,200 vs $2,000+), making it an excellent value for the performance and ISO4210 safety certification.

    FAQ

    Is this wheelset suitable for gravel riding?

    Yes, the 40mm depth and tubeless-ready design make it versatile for both road and gravel. With a wide tire clearance (up to 45mm), you can run aggressive treads for mixed terrain while enjoying low pressures for comfort and traction.

    What tire pressure should I run?

    For road use, start around 80-90 psi for 25mm tires. For gravel, lower to 35-45 psi for 40mm tires. Tubeless setups allow lower pressures without pinch flats, improving comfort and grip.

    Is the hub engagement suitable for climbing and sprinting?

    The hub features a 54-tooth ratchet with 6.7 degrees of engagement, providing quick acceleration response. This is ideal for technical sections and sprinting.

    Can I upgrade to these wheels without changing my bike?

    The wheelset fits standard 12x100mm front and 12x142mm rear through-axles, which are common on modern disc brake road and gravel bikes. Ensure your frame and fork are compatible with disc brakes.

    What is the weight limit for this wheelset?

    The wheelset is rated for a system weight of 120kg (rider plus bike). For riders above this, we recommend consulting our technical team for tailored advice.
