    Le Bola CE 40R sono ruote a disco da 40 mm in carbonio UD T800, montate su mozzi DT Swiss OEM 36T con raggi in carbonio lamellari, 1270 g, ideali per bici da corsa e gravel orientate alla salita.

    La lama da salita: 40 mm, 1270 g, sistema a cricchetto DT Swiss. Le Bola CE 40R abbinano un cerchio in carbonio T800 opaco da 40 mm (28-30 mm esterno, 21-24 mm interno) a un mozzo a cricchetto DT Swiss OEM 36T e raggi in carbonio lamellari: una soluzione all-rounder votata alla salita, abbastanza bassa per arrampicarsi e abbastanza profonda per l'aerodinamica.

    Guida all'acquisto.

    Larghezza interna - 21 mm: 28c a 70-85 PSI per asfalto liscio.

    Larghezza interna - 24 mm: 32c a 50-60 PSI per uso all-road.

    Peso massimo del ciclista: classificato fino a 105 kg - il più basso della serie CE; i ciclisti più pesanti dovrebbero considerare le CE 45R.

    Serie con stessa altezza: le EXP 40R (~999 $) mantengono i raggi in acciaio CX-Ray e le EXT 40R (~1111 $) offrono cuscinetti in ceramica più leggeri; le CE 40R combinano un mozzo a cricchetto DT con raggi in carbonio lamellari.

    Altezza adiacente: le CE 45R offrono maggiore aerodinamicità: scegliete le 40R per la salita, le 45R per la velocità.

    Pubblico di destinazione e note d'uso.

    Telai stradali e gravel con freni a disco, perno passante 12x100/12x142.

    Peso massimo del sistema 105 kg (il più basso della serie CE); i ciclisti più pesanti dovrebbero considerare le CE 45R (110 kg).

    Non adatte a fuoristrada estremo.

    L'esperienza di guida che ti attende.

    La prima salita lo conferma: ogni tratto ripido si affronta senza il peso che ricordavi, e l'altezza del cerchio non sembra mai gravare sulla pedalata. In discesa mantengono la linea nonostante le raffiche; il cricchetto emette un clic preciso in uscita da ogni tornante. Spedizione gratuita e garanzia di 3 anni sui cerchi e 2 anni sul set di ruote rendono le salite un po' più amichevoli.

    Trade-offs & Considerations
    • Aero vs Climbing: This 40mm depth balances aerodynamic efficiency with lightweight 1270g, favoring climbing over deep-section aero, but still offering decent aero for flat sections.
    • Stiffness vs Compliance: The T800 carbon and foil carbon spokes provide high stiffness for power transfer, while the wide rim profile allows lower tire pressures for added compliance on rough roads.
    • Weight vs Durability: At 1270g, the wheelset is lightweight but relies on durable DT Swiss hub and carbon construction; however, it may be less robust than heavier alloy wheelsets for extreme abuse.
    • Crosswind vs Aero: The 40mm depth reduces crosswind sensitivity compared to 50mm+ rims, making it more controllable in gusty conditions, but it sacrifices some aerodynamic drag reduction.

    FAQ

    What riding scenarios is this wheelset best suited for?

    This wheelset is designed for mixed road and gravel riding, excelling in climbing, endurance, and daily training. Its 40mm depth and lightweight 1270g make it versatile for varied terrain, and the wide rim supports larger tires for comfort on rough roads.

    How does the weight affect stiffness and responsiveness?

    The lightweight construction (1270g) reduces rotational mass, improving acceleration and climbing efficiency. The T800 carbon rims and foil carbon spokes provide high lateral stiffness, ensuring responsive power transfer without excessive weight penalty.

    What is the hub engagement and how does it impact performance?

    The DT Swiss OEM hub features a 36-tooth ratchet, providing fast and reliable engagement on technical sections. This quick engagement enhances acceleration out of corners, making it ideal for racing and group rides.

    What tire pressures are recommended for tubeless setup?

    For tubeless setups, pressures typically range from 60-80 psi for 28-32c tires, depending on rider weight and terrain. The wide rim allows lower pressures for better traction and comfort without compromising rolling resistance.

    What industry hot topics does this wheelset address?

    This wheelset addresses bearing longevity with DT Swiss steel bearings known for reliability, and spoke tension maintained by the straight-pull foil carbon spokes. It also meets ISO 4210-7 certification for safety and REACH compliance for material standards, addressing impact damage and crosswind handling concerns.
