# 29er Asymmetric Carbon MTB Rim, 30mm Internal Width for Trail, Enduro, Freeride Take confident lines on aggressive trails and freeride descents with a rim engineered to balance strength, weight, and precise handling. The 29er Asymmetric Carbon MTB Rim is built from Toray carbon to support 2.3–2.6" tires while delivering predictable performance for trail, enduro, and freeride riding contexts. ## 29er Asymmetric Carbon MTB Rim - Designed for trail, enduro and freeride use Whether you are upgrading a stock wheelset or building a bespoke wheel for more demanding terrain, this rim focuses on the ride qualities that matter: lateral stability, even spoke tension and tubeless compatibility. Its asymmetric U-shaped profile and 30mm internal width provide a planted feel under braking and through corners while keeping rotational mass competitive for climbs and accelerations. ### Why it fits your routine - **Optimized tire support:** 30mm internal width is tuned for 2.3–2.6" MTB tires, promoting better tire profile, increased traction, and consistent sidewall support on rough terrain. - **Balanced spoke tension:** Asymmetric U-profile moves the spoke bed to equalize tension across the wheel, improving long-term trueness and reducing maintenance. - **Weight options to match priorities:** Choose Standard at 455 ±10g per rim for durability or Superlight at 385 ±10g per rim for performance-focused builds. - **Durable construction:** Premium Toray carbon layup with multi-stage quality control offers robust forward compressive strength (>300kg) and lateral torsion resistance (>50kg). - **Tubeless ready:** Hookless, tubeless-compatible design supports modern MTB tubeless setups to lower rolling resistance and reduce punctures. - **Precision manufacturing:** Flatness tolerance under 0.3mm and a 2-year global warranty provide measurable quality and after-sales protection. - **Factory-direct value:** Engineered to deliver Toray carbon performance with cost-effective pricing suited for individual upgrades, shop builds, and B2B supply. Key specifications include 29" (622mm BSD) rim size, 30mm rim height, 36mm external width, and compatibility intended for trail, enduro, and freeride riding. The rim compares favorably to higher-priced premium models by offering a similar carbon material standard and strict QC while remaining factory-direct in pricing. These design choices make the rim a practical option for riders upgrading from aluminum or worn carbon, for builders specifying balanced wheelsets, and for shops or OEM partners seeking consistent, serviceable components. ## Details - **Price:** 310.0 USD - 320.0 USD - **Type:** Bicycle Wheel Rims - **Tags:** 29 inch bike rim, 29 inch mountain bike rim, 29er carbon rim, 29er MTB rim, asymmetric MTB rim, asymmetric wheel build, B2B bike component, carbon mountain bike rim, custom MTB wheel build, enduro carbon rim, enduro wheel upgrade, freeride bike rim, freeride MTB rim, lightweight trail rim, mountain bike rim 29 inch, mtb, rims, Toray carbon fiber rim, trail MTB rim, tubeless ready rim, tubeless-ready carbon rim, U-shape profile rim, wide internal rim ## Variants | Variant | Price | Available | |---------|-------|-----------| | UD Matt / 28/28 / Normal | 310.00 USD | In stock | | UD Matt / 28/28 / Superlight | 320.00 USD | In stock | | UD Matt / 32/32 / Normal | 310.00 USD | In stock | | UD Matt / 32/32 / Superlight | 320.00 USD | In stock | | UD Matt / Customs / Normal | 310.00 USD | In stock | | UD Matt / Customs / Superlight | 320.00 USD | In stock | | UD Glossy / 28/28 / Normal | 310.00 USD | In stock | | UD Glossy / 28/28 / Superlight | 320.00 USD | In stock | | UD Glossy / 32/32 / Normal | 310.00 USD | In stock | | UD Glossy / 32/32 / Superlight | 320.00 USD | In stock | | UD Glossy / Customs / Normal | 310.00 USD | In stock | | UD Glossy / Customs / Superlight | 320.00 USD | In stock | | Marble Matt / 28/28 / Normal | 310.00 USD | In stock | | Marble Matt / 28/28 / Superlight | 320.00 USD | In stock | | Marble Matt / 32/32 / Normal | 310.00 USD | In stock | | Marble Matt / 32/32 / Superlight | 320.00 USD | In stock | | Marble Matt / Customs / Normal | 310.00 USD | In stock | | Marble Matt / Customs / Superlight | 320.00 USD | In stock | | Marble Glossy / 28/28 / Normal | 310.00 USD | In stock | | Marble Glossy / 28/28 / Superlight | 320.00 USD | In stock | | Marble Glossy / 32/32 / Normal | 310.00 USD | In stock | | Marble Glossy / 32/32 / Superlight | 320.00 USD | In stock | | Marble Glossy / Customs / Normal | 310.00 USD | In stock | | Marble Glossy / Customs / Superlight | 320.00 USD | In stock | ## Images - 29er Asymmetric Carbon MTB Rim set featuring a 30mm height and 30mm inner width, designed for freeride and enduro use. - 32er Asymmetric Carbon MTB Rim | 25mm Height, 30mm Inner Width | Tubeless-Ready | BOLA - 32er Asymmetric Carbon MTB Rim | 25mm Height, 30mm Inner Width | Tubeless-Ready | BOLA - 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 - **Product rating count:** 1 - **Related products settings:** ahead - **AI Summary:** The Bola 29er Asymmetric Carbon MTB Rim is a Toray carbon 29-inch mountain bike rim for riders and wheel builders seeking a lightweight, stable wheel platform for aggressive trail, freeride, and enduro riding.
