    The Bola CLA 40R 700C Road Carbon Disc Tubeless Wheelset - a light, versatile 40mm aero set for road and gravel, built in Toray T700/T800 carbon.

    Ride faster on mixed surfaces with a wheelset engineered to balance aerodynamics, durability, and everyday usability. The Bola CLA 40R pairs a 40mm rim with tubeless-ready construction and a light ~1370g profile - a confident carbon upgrade without excess cost.

    Buying Guide.

    Internal width - 21mm: run a 28mm tire at 75-90 PSI for smooth tarmac.

    Internal width - 24mm: cup a 30-32mm tire at 65-80 PSI for mixed roads.

    Internal width - 26mm: settle a 35-45mm tire at 50-65 PSI on rough chipseal and gravel.

    Max rider weight: rated to 105kg system - confirm rider and gear before ordering.

    Same-depth series: among its shallower road tier the ELT 40R adds a ceramic hub at $579 and the ULT 40R adds CX-Ray spokes at $698 - choose this CLA as the value all-rounder.

    Adjacent depth: the CLA 50R adds flat-course aero, while this 40R stays lighter and calmer in gusts - the pick for riders who climb.

    Target Audience & Usage Notes.

    For road and gravel riders upgrading from alloy, training riders, and climbers.

    Requires 12x100/12x142 thru-axles and disc brakes.

    Max system weight 105kg.

    Tubeless-ready; clincher-compatible.

    The Ride That Awaits.

    A rolling-hill loop feels almost easy: the shallow rim carries you over the rollers without crosswind chatter, and the lively pair makes every kick on the climb feel like a gift. Tubeless pressures down around 60psi swallow road chatter whole. Free shipping, VAT included, and a 3-year rim / 2-year wheelset warranty with 30% crash-replacement cover mean you upgrade today and feel it on the next ride.

    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.
