    The Bola CE 40R is a 40mm T800 UD carbon disc wheelset on a DT Swiss OEM 36T hub with foil carbon spokes, 1270g, for climbing-oriented road and gravel riding.

    The climbing blade: 40mm, 1270g, DT Swiss ratchet. The Bola CE 40R pairs a 40mm T800 matte rim (28-30mm external, 21-24mm internal) with a DT Swiss OEM 36T ratchet hub and foil carbon spokes — a climbing-oriented all-rounder, shallow enough to climb, deep enough to aero.

    Buying Guide.

    Internal width - 21mm: 28c at 70-85 PSI for smooth tarmac.

    Internal width - 24mm: 32c at 50-60 PSI for all-road.

    Max rider weight: rated to 105kg - the lowest in CE; heavier riders should consider the CE 45R.

    Same-depth series: the EXP 40R (~$999) keeps steel CX-Ray spokes and the EXT 40R (~$1111) goes ceramic lighter; the CE 40R blends a DT ratchet hub with foil carbon spokes.

    Adjacent depth: the CE 45R above adds aero - choose the 40R for climbing, the 45R for speed.

    Target Audience & Usage Notes.

    Disc-brake road and gravel frames, 12x100/12x142 thru-axle.

    Max system weight 105kg (lowest in CE); heavier riders should consider the CE 45R (110kg).

    Not for extreme off-road.

    The Ride That Awaits.

    The first climb confirms it - each steep pitch spins up without the burden you remember, the rim depth never once feeling like a weight. The descent holds its line through the gusts; the ratchet clicks clean out of every hairpin. Free shipping and a 3-year rim / 2-year wheelset warranty mean the climbs are about to get friendlier.

    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.
