# Bola ULT 40R 700C Carbon Disc Wheelset, 40mm Tubeless, 1210g, T800 Carbon, Road and Gravel

The Bola ULT 40R 700C Carbon Disc Wheelset delivers a balanced combination of low weight, aerodynamic efficiency, and tubeless-ready versatility for road and gravel riders. Constructed from Toray T800 unidirectional matte carbon, the set weighs a verified 1210g (±30g) and is REACH compliant with ISO 4210-7 testing for structural reliability.

## Key Features

-   **Rim Depth:** 40mm aerodynamic profile for all-round performance.
-   **External Rim Width:** 28mm or 30mm options to optimize modern tire shapes.
-   **Tire Compatibility:** Tubeless-ready; recommended 28–48mm tire range.
-   **Hubs:** TPI ceramic bearing hubs with 54T ratchet for responsive engagement.
-   **Spokes:** Sapim CX-Ray stainless steel, 2x/1x lacing patterns.
-   **Axles:** 12x100mm front and 12x142mm rear thru-axle; quick-release compatible.
-   **Warranty:** 24 months with Bola global support.

## Performance & Use

At 1210g per set, the ULT 40R competes with higher-priced models by offering reduced rotational mass for quicker accelerations and improved climbing while maintaining rim stiffness and compliance suitable for mixed surfaces. The wider internal profile supports modern, larger-volume tires for enhanced comfort and traction on gravel, endurance road, and mixed-terrain rides. Compared with deeper 50mm race-specific rims, the 40mm depth offers a more controllable crosswind profile and broader everyday usability.

These wheels are ideal for riders seeking a cost-effective carbon upgrade, shops and OEMs requiring competitive value, and cyclists who need a single wheelset capable of covering long endurance rides, gravel events, and variable road conditions.
