# Bola 700c Carbon Tubeless Road Rim — 45mm Depth, 28mm Outer Width, 21mm/23mm Inner (Hooked or Hookless) Ride longer, push harder, and dial in faster race setups with a rim designed for modern tubeless road performance. The Bola 700c carbon rim blends a 45mm aerodynamic profile with a wide 28mm outer width to create a stable, aerodynamically efficient platform for 28–35c tires. Choose hooked or hookless inner widths to match tire technology, pressure preferences, and mixed-use riding plans. ## Bola 700c Carbon Tubeless Road Rim - Designed for performance road and race builds The rim's tubeless-ready bed and U-shaped 45mm profile deliver measurable aero gains when paired with appropriately sized tires, while the wider rim section increases air volume for improved compliance and lower rolling resistance. Structural tolerances and strength ratings focus on long-term stability and predictable handling whether you build a training wheelset or a race-oriented lightweight pair. ### Why it fits your routine - **Aero and volume balance:** 45mm rim depth with 28mm outer width forms a continuous airfoil with 28–32c tires to reduce the 'light bulb' effect and improve aerodynamics for fast group rides and race efforts. - **Tubeless-ready out of the box:** Factory tubeless bed requires no conversion tape, making setup straightforward for tubeless road tires and sealant installation. - **Choice of bead type:** Hooked (21mm inner) supports a wider range of clincher and tubeless tires and higher pressures; hookless (23mm inner) increases air volume and ride compliance when used with ETRTO-approved hookless-compatible tires at recommended pressures. - **Pressure range and compatibility:** Rim supports typical road pressures with a stated minimum/maximum tire pressure range of 100/125 psi for compatible setups and recommended hookless operating pressures of approximately 72–87 psi with compliant tires when using the hookless option. - **Multiple weight grades:** Available in Standard (430 ±15 g), Super Light (405 ±10 g), Ultra Light (375 ±10 g), and Extreme Light (355 ±10 g) per rim to tailor wheelset weight for training durability or race-optimized builds. - **Robust structural specs:** Forward compressive strength >300 kg, lateral torsion resistance >50 kg, spoke hole tension rating >280 kg, dynamic equilibrium <3 g, flatness tolerance <0.15 mm, and roundness tolerance <0.3 mm. - **Customizable details:** ERD 548mm with customizable valve hole (standard 6.5mm), spoke hole diameter (standard 4.5mm), assembly hole diameter (standard 7.5mm), and nipple angles (front 7°; rear 5°–7°) to match build preferences. - **Hub and brake compatibility:** Built to accept standard road hub widths (100mm front; 130mm or 142mm rear) and can be specified for center-lock or 6-bolt disc configurations at the build stage. - **Rim width guidance:** The 21mm inner width (hooked) is optimized for 25c–32c tires; the 23mm inner width (hookless) is best matched to 28c–35c tires for an aerodynamically flush profile. - **Load rating:** Maximum recommended rider weight is 120 kg (264 lb), providing a clear guideline for safe use across rider types. Every rim arrives with precise manufacturing tolerances to support consistent wheel builds: ERD 548mm, valve hole customizable at 6.5mm, spoke hole 4.5mm, and assembly hole 7.5mm, enabling builders to optimize spoke choice and nipple fit for the intended application. ## Details - **Price:** 310.0 USD - 340.0 USD - **Type:** Carbon Road Rim - **Tags:** 28mm wide, 28mm wide rim, 50mm rim depth, 700c, 700c bike rim, 700c rim, aero bike rim, bolacarbon, carbon bike rim, carbon cycling rim, carbon road rim, carbon tubeless road rim, endurance rim, hooked rim, hooked tubeless rim, hookless rim, https, lightweight climbing rim, lightweight road rim, racing rim, rims, road, road racing rim, tubeless, tubeless road rim, type, wide rim ## Variants | Variant | Price | Available | |---------|-------|-----------| | UD Matt / 20/20 / Standard | 310.00 USD | In stock | | UD Glossy / 20/20 / Standard | 310.00 USD | In stock | | Marble Matt / 20/20 / Standard | 310.00 USD | In stock | | Marble Glossy / 20/20 / Standard | 310.00 USD | In stock | | UD Matt / 20/20 / Superlight | 320.00 USD | In stock | | UD Matt / 20/20 / Ultralight | 330.00 USD | In stock | | UD Matt / 20/20 / Extremlight | 340.00 USD | In stock | | UD Matt / 24/24 / Standard | 310.00 USD | In stock | | UD Matt / 24/24 / Superlight | 320.00 USD | In stock | | UD Matt / 24/24 / Ultralight | 330.00 USD | In stock | | UD Matt / 24/24 / Extremlight | 340.00 USD | In stock | | UD Matt / Customs / Standard | 310.00 USD | In stock | | UD Matt / Customs / Superlight | 320.00 USD | In stock | | UD Matt / Customs / Ultralight | 330.00 USD | In stock | | UD Matt / Customs / Extremlight | 340.00 USD | In stock | | UD Glossy / 20/20 / Superlight | 320.00 USD | In stock | | UD Glossy / 20/20 / Ultralight | 330.00 USD | In stock | | UD Glossy / 20/20 / Extremlight | 340.00 USD | In stock | | UD Glossy / 24/24 / Standard | 310.00 USD | In stock | | UD Glossy / 24/24 / Superlight | 320.00 USD | In stock | | UD Glossy / 24/24 / Ultralight | 330.00 USD | In stock | | UD Glossy / 24/24 / Extremlight | 340.00 USD | In stock | | UD Glossy / Customs / Standard | 310.00 USD | In stock | | UD Glossy / Customs / Superlight | 320.00 USD | In stock | | UD Glossy / Customs / Ultralight | 330.00 USD | In stock | | UD Glossy / Customs / Extremlight | 340.00 USD | In stock | | Marble Matt / 20/20 / Superlight | 320.00 USD | In stock | | Marble Matt / 20/20 / Ultralight | 330.00 USD | In stock | | Marble Matt / 20/20 / Extremlight | 340.00 USD | In stock | | Marble Matt / 24/24 / Standard | 310.00 USD | In stock | | Marble Matt / 24/24 / Superlight | 320.00 USD | In stock | | Marble Matt / 24/24 / Ultralight | 330.00 USD | In stock | | Marble Matt / 24/24 / Extremlight | 340.00 USD | In stock | | Marble Matt / Customs / Standard | 310.00 USD | In stock | | Marble Matt / Customs / Superlight | 320.00 USD | In stock | | Marble Matt / Customs / Ultralight | 330.00 USD | In stock | | Marble Matt / Customs / Extremlight | 340.00 USD | In stock | | Marble Glossy / 20/20 / Superlight | 320.00 USD | In stock | | Marble Glossy / 20/20 / Ultralight | 330.00 USD | In stock | | Marble Glossy / 20/20 / Extremlight | 340.00 USD | In stock | | Marble Glossy / 24/24 / Standard | 310.00 USD | In stock | | Marble Glossy / 24/24 / Superlight | 320.00 USD | In stock | | Marble Glossy / 24/24 / Ultralight | 330.00 USD | In stock | | Marble Glossy / 24/24 / Extremlight | 340.00 USD | In stock | | Marble Glossy / Customs / Standard | 310.00 USD | In stock | | Marble Glossy / Customs / Superlight | 320.00 USD | In stock | | Marble Glossy / Customs / Ultralight | 330.00 USD | In stock | | Marble Glossy / Customs / Extremlight | 340.00 USD | In stock | ## Images - Bola 700c Carbon Tubeless Road Rim, 45mm Depth, 28mm Outer Width, 21mm/23mm Inner, Hooked or Hookless Carbon Fiber Sporting Goods - Bola 700c Carbon Tubeless Road Rim, 45mm Depth, 28mm Outer Width, 21mm/23mm Inner, Hooked or Hookless Carbon Fiber Sporting Goods - BOLA 88mm Aero Carbon Rim 700C – Hooked Tubeless, 27mm/20mm, TT & Triathlon（副本） - BOLA 88mm Aero Carbon Rim 700C – Hooked Tubeless, 27mm/20mm, TT & Triathlon（副本） - Bola 700c Carbon Tubeless Road Rim – 50mm Deep, 28mm Wide, Hooked or Hookless, 370–470g Carbon Fiber Sporting Goods - Bola 700c Carbon Tubeless Road Rim – 50mm Deep, 28mm Wide, Hooked or Hookless, 370–470g Carbon Fiber Sporting Goods ## Additional Information - **AI Summary:** The Bola 700c Carbon Tubeless Road Rim is a 45mm deep carbon rim built for road racing and endurance riders who want a tubeless-ready wheel without conversion tape.
