# BOLA 32er 45mm Carbon Road & Gravel Rim | 38mm Outer, 32mm Inner, Tubeless Ready

Take the confidence of aerodynamic performance to mixed roads and long rides with a rim designed to suit modern wide-tire builds. The BOLA 32er 45mm carbon rim pairs a 45mm deep aero profile with a wide 32–33mm internal platform to support tubeless setups for both road and gravel bikes. It’s engineered to deliver predictable handling, tire volume compatibility, and certified safety without a heavy brand premium.

## BOLA 32er 45mm Carbon Road & Gravel Rim - Designed for road and gravel endurance

Riders will feel the practical benefits on sustained rides and variable terrain: the 45mm depth helps slice through wind for improved efficiency while the wide internal width lets you run 28–32mm tires at comfortable pressures, improving comfort and traction. Built from Toray T700 UD carbon and tested to ETRTO and ISO standards, this rim aims to balance lightweight performance and structural reliability for training, mixed-surface rides, and endurance events.

### Why it fits your routine

-   **Aerodynamic depth:** 45mm rim profile reduces drag for sustained speed on flats and rolling terrain.
-   **Wide tire support:** 38mm outer width with 32mm (hooked) / 33mm (hookless) internal width is optimized for tubeless tires in the 28–32mm range.
-   **Tubeless-ready construction:** Compatible with modern tubeless and clincher setups to lower rolling resistance and reduce pinch flats at appropriate pressures.
-   **Trusted material:** Toray T700 UD carbon fiber offers a strong, cost-effective layup used across multiple weight options (445g–530g) to suit different priorities.
-   **Disc brake compatibility:** Supports both 6-bolt and Centerlock disc brake systems for versatile wheel builds.
-   **Standards and testing:** ETRTO and ISO certified with dynamic balance testing to meet industry safety and fitment expectations.
-   **Practical sizing:** 32-inch (ISO 696mm BSD) rim size with ERD 612mm for standard spoke and hub compatibility in modern road and gravel wheel builds.
-   **Warranty:** 3-year manufacturer warranty against defects (excluding crash damage), offering reassurance for regular use and retail or OEM stocking.

Engineers selected an asymmetric U-shaped profile to improve lateral stiffness and aerodynamics while preserving predictable crosswind handling, and the rim is available in multiple layups to prioritize lower weight or added durability depending on build goals.
