# Bola 700C Carbon Tubeless Ready Rim — 88mm Deep, 25mm Outer, U-Shape (TT & Triathlon) When you need every second and every watt to count, this 700C full-carbon rim delivers the aerodynamic advantage and controlled handling that time trial and triathlon riders expect. Built with an 88mm U-shaped profile and a 25mm outer width, it is engineered to pair with road and time-trial setups where speed, stability, and predictable tire behavior are priorities. Available in Standard and Superlight weights, the rim supports tubeless setups and a rider limit of 100 kg for racing and training scenarios. ## Bola 700C Carbon Tubeless Ready Rim - Designed for TT and Triathlon The deep 88mm profile smooths airflow and reduces drag on flat and rolling courses while the 25mm outer width and 18mm inner channel provide stable tire support for 25–32mm road tires. Precision tolerances and ISO-tested structural metrics ensure consistent ride quality, allowing riders to focus on pacing and power rather than equipment unpredictability. The construction balances stiffness for power transfer with controlled handling characteristics, giving a confident feel during sustained efforts and high-speed sections. Available in two trim weights (690g standard and 650g Superlight ±15g), the rim suits riders and brands prioritizing low mass without sacrificing certified strength. ### Why it fits your routine - **Aerodynamic performance:** 88mm deep U-shaped profile reduces drag for sustained high-speed efforts typical of time trials and triathlons. - **Optimized tyre pairing:** 25mm outer width and 18mm inner channel are tuned for 25–32mm tyres to balance aero integration and rolling resistance. - **Tubeless ready:** Compatible with tubeless tyre setups for lower rolling resistance and improved puncture resilience in race conditions. - **Weight options:** Choose Standard (approx. 690g) or Superlight (approx. 650g) to match your priority between durability and mass reduction. - **Structural certification:** ISO lab-tested strengths—forward compressive >300 kg, lateral torsion >50 kg, spoke hole tension >280 kg—ensure reliable performance under load. - **Precision build quality:** Dynamic equilibrium <3g and tight flatness/roundness tolerances (<0.15mm / <0.3mm) for predictable wheelbuilding and consistent ride feel. - **High pressure rating:** Maximum tire pressure rated up to 125 psi, accommodating high-pressure road setups when appropriate. - **Rider limit and safety:** Rated for riders up to 100 kg; warranty covers manufacturing defects for 3 years. Practical details for wheelbuilders and spec sheets: 700C rim size with an 18mm internal width and 25mm external width, ERD 462mm for spoke length calculation, and a 6.5mm Presta valve hole. The rim is a full carbon clincher designed for tubeless-ready assembly and is manufactured to ISO-compliant testing standards in China, trusted by small and medium cycling brands across Europe and North America. ## Details - **Price:** 390.0 USD - **Type:** Carbon Bicycle Clincher Rim - **Tags:** 18mm inner width rim, 25mm wide, 25mm wide carbon rim, 25mm wide rim, 50mm deep road rim, 700c, 700C carbon clincher rim, 700C rim, 88mm, 88mm deep rim, aero carbon rim, aero road rim, bolacarbon, carbon, carbon bike rim, carbon clincher rim, custom carbon rim, https, ISO tested carbon rim, lightweight carbon rim, lightweight road rim, performance road rim, rims, time trial rim, triathlon bike rim, tubeless ready rim, type, U-shape rim, U-shape road rim ## Variants | Variant | Price | Available | |---------|-------|-----------| | UD Matt / 20/24 / Standard | 390.00 USD | In stock | | UD Matt / 20/24 / Superlight | 390.00 USD | In stock | | UD Matt / 24/24 / Standard | 390.00 USD | In stock | | UD Matt / 24/24 / Superlight | 390.00 USD | In stock | | UD Matt / Customs / Standard | 390.00 USD | In stock | | UD Matt / Customs / Superlight | 390.00 USD | In stock | | UD Glossy / 20/24 / Standard | 390.00 USD | In stock | | UD Glossy / 20/24 / Superlight | 390.00 USD | In stock | | UD Glossy / 24/24 / Standard | 390.00 USD | In stock | | UD Glossy / 24/24 / Superlight | 390.00 USD | In stock | | UD Glossy / Customs / Standard | 390.00 USD | In stock | | UD Glossy / Customs / Superlight | 390.00 USD | In stock | | Marble Matt / 20/24 / Standard | 390.00 USD | In stock | | Marble Matt / 20/24 / Superlight | 390.00 USD | In stock | | Marble Matt / 24/24 / Standard | 390.00 USD | In stock | | Marble Matt / 24/24 / Superlight | 390.00 USD | In stock | | Marble Matt / Customs / Standard | 390.00 USD | In stock | | Marble Matt / Customs / Superlight | 390.00 USD | In stock | | Marble Glossy / 20/24 / Standard | 390.00 USD | In stock | | Marble Glossy / 20/24 / Superlight | 390.00 USD | In stock | | Marble Glossy / 24/24 / Standard | 390.00 USD | In stock | | Marble Glossy / 24/24 / Superlight | 390.00 USD | In stock | | Marble Glossy / Customs / Standard | 390.00 USD | In stock | | Marble Glossy / Customs / Superlight | 390.00 USD | In stock | ## Images - 700C Carbon Tubeless Ready Rim, 88mm Deep, 25mm Wide, U-Shape for TT and Triathlon, Bola Carbon Fiber Sporting Goods - 700C Carbon Tubeless Ready Rim, 88mm Deep, 25mm Wide, U-Shape for TT and Triathlon, Bola Carbon Fiber Sporting Goods - Detail view of carbon fiber layup on 700C 50mm clincher bicycle rim - Surface finish of 700C carbon clincher rim, 50mm depth - 29er Asymmetric Carbon MTB Rim | 30mm Height, 30mm Inner Width | Freeride & Enduro Carbon Fiber Sporting Goods - 29er Asymmetric Carbon MTB Rim | 30mm Height, 30mm Inner Width | Freeride & Enduro Carbon Fiber Sporting Goods ## Additional Information - **Related products settings:** ahead - **AI Summary:** The Bola 700C Carbon Tubeless Ready Rim 88mm is a full-carbon 700C rim made for time trial and triathlon cyclists building high-profile aerodynamic wheels.
