Most testers report predictable handling even in variable wind conditions. **Should I choose hookless or hooked for tubeless compatibility?** Hookless rims offer a smoother tubeless tire interface and can reduce pinch flats at lower pressures, but both hookless (ETRTO certified) and hooked are compatible with modern tubeless-ready tires. Always check tire manufacturer compatibility and pressure limits. **Is this rim suitable for endurance or gran fondo racing?** Yes, the 45mm profile delivers a blend of aerodynamic benefit and handling stability for endurance events. It is designed for all-day riding comfort and efficiency. **What is unique about the 32-inch size and ERD 612mm?** The 32-inch (ISO 696mm) BSD matches modern road and gravel standards, allowing optimized geometry for larger-volume tires, which improves comfort, compliance, and handling over longer distances. ## Details - **Price:** 310.0 USD - 340.0 USD - **Type:** Carbon Road & Gravel Rim - **Tags:** 32 inch, 32mm internal width, 45mm carbon rim, 45mm deep rim, BOLA 32er, BOLA 32er rim, carbon gravel rim, carbon road rim, disc brake carbon rim, ETRTO certified, lightweight bike rim, OEM carbon rim, rims, tubeless rim, tubeless-ready rim ## Variants | Variant | Price | Available | |---------|-------|-----------| | UD Matt / 20/20 / Standard | 310.00 USD | In stock | | UD Matt / 20/20 / Super Light | 320.00 USD | In stock | | UD Matt / 20/20 / Ultra Light | 330.00 USD | In stock | | UD Matt / 20/20 / Extreme Light | 340.00 USD | In stock | | UD Matt / 24/24 / Standard | 310.00 USD | In stock | | UD Matt / 24/24 / Super Light | 320.00 USD | In stock | | UD Matt / 24/24 / Ultra Light | 330.00 USD | In stock | | UD Matt / 24/24 / Extreme Light | 340.00 USD | In stock | | UD Matt / Customized / Standard | 310.00 USD | In stock | | UD Matt / Customized / Super Light | 320.00 USD | In stock | | UD Matt / Customized / Ultra Light | 330.00 USD | In stock | | UD Matt / Customized / Extreme Light | 340.00 USD | In stock | | UD Glossy / 20/20 / Standard | 310.00 USD | In stock | | UD Glossy / 20/20 / Super Light | 320.00 USD | In stock | | UD Glossy / 20/20 / Ultra Light | 330.00 USD | In stock | | UD Glossy / 20/20 / Extreme Light | 340.00 USD | In stock | | UD Glossy / 24/24 / Standard | 310.00 USD | In stock | | UD Glossy / 24/24 / Super Light | 320.00 USD | In stock | | UD Glossy / 24/24 / Ultra Light | 330.00 USD | In stock | | UD Glossy / 24/24 / Extreme Light | 340.00 USD | In stock | | UD Glossy / Customized / Standard | 310.00 USD | In stock | | UD Glossy / Customized / Super Light | 320.00 USD | In stock | | UD Glossy / Customized / Ultra Light | 330.00 USD | In stock | | UD Glossy / Customized / Extreme Light | 340.00 USD | In stock | | 3K Matt / 20/20 / Standard | 310.00 USD | In stock | | 3K Matt / 20/20 / Super Light | 320.00 USD | In stock | | 3K Matt / 20/20 / Ultra Light | 330.00 USD | In stock | | 3K Matt / 20/20 / Extreme Light | 340.00 USD | In stock | | 3K Matt / 24/24 / Standard | 310.00 USD | In stock | | 3K Matt / 24/24 / Super Light | 320.00 USD | In stock | | 3K Matt / 24/24 / Ultra Light | 330.00 USD | In stock | | 3K Matt / 24/24 / Extreme Light | 340.00 USD | In stock | | 3K Matt / Customized / Standard | 310.00 USD | In stock | | 3K Matt / Customized / Super Light | 320.00 USD | In stock | | 3K Matt / Customized / Ultra Light | 330.00 USD | In stock | | 3K Matt / Customized / Extreme Light | 340.00 USD | In stock | | 3K Glossy / 20/20 / Standard | 310.00 USD | In stock | | 3K Glossy / 20/20 / Super Light | 320.00 USD | In stock | | 3K Glossy / 20/20 / Ultra Light | 330.00 USD | In stock | | 3K Glossy / 20/20 / Extreme Light | 340.00 USD | In stock | | 3K Glossy / 24/24 / Standard | 310.00 USD | In stock | | 3K Glossy / 24/24 / Super Light | 320.00 USD | In stock | | 3K Glossy / 24/24 / Ultra Light | 330.00 USD | In stock | | 3K Glossy / 24/24 / Extreme Light | 340.00 USD | In stock | | 3K Glossy / Customized / Standard | 310.00 USD | In stock | | 3K Glossy / Customized / Super Light | 320.00 USD | In stock | | 3K Glossy / Customized / Ultra Light | 330.00 USD | In stock | | 3K Glossy / Customized / Extreme Light | 340.00 USD | In stock | | Marble Matt / 20/20 / Standard | 310.00 USD | In stock | | Marble Matt / 20/20 / Super Light | 320.00 USD | In stock | ## Images - BOLA 32er Carbon Road Rim featuring a 45mm deep tubeless design with 38mm outer and 32mm inner width. - BOLA 32er Carbon Road Rim diagram showing dimensions: 45mm deep, 38mm outer width, 32mm inner width, and weight specification - BOLA 700C carbon road rim, matte finish, detailed hooked tubeless bead seat compatibility - 40mm BOLA carbon road rim, matte UD carbon finish, close-up on fiber layup and rim wall detail - BOLA 32er 45mm Carbon Road Rim | 38mm Outer 32mm Inner Tubeless Carbon Fiber Sporting Goods - BOLA 32er 45mm Carbon Road Rim | 38mm Outer 32mm Inner Tubeless Carbon Fiber Sporting Goods ## Additional Information - **Product rating count:** 1 - **Search product boosts:** carbon rims factory whole sales disctributor dealer oem custmized customs - **Related products settings:** ahead - **AI Summary:** BOLA 32er 45mm carbon rim features a 38mm outer and 32mm (hooked) or 33mm (hookless) inner width, optimized for tubeless setups and 28–32mm tires.
