The Bola CE 40R pairs a 40mm deep T800 UD carbon rim and wide profile with foil carbon spokes and a DT Swiss OEM 36T ratchet hub to deliver versatile performance for competitive and serious recreational cyclists. ## Bola CE 40R Carbon Disc Wheelset - Designed for road and gravel riding The 28mm or 30mm external rim width was developed to optimize modern 28–32c tires, producing a stable tire profile that improves grip and comfort on mixed surfaces. At 1270g (excluding tape and valves), the wheelset reduces rotational mass for quicker accelerations and easier climbing while the 40mm rim depth maintains aerodynamic efficiency without excessive crosswind sensitivity. ### Why it fits your routine - **Purpose-built rim geometry:** 40mm depth with 28mm or 30mm external width and 21mm or 24mm internal width to support 28–32c tires and improved tire shape. - **High-grade construction:** T800 UD matte carbon fiber rim for a balance of stiffness and measured compliance. - **Lightweight performance:** 1270g wheelset weight (excluding tape/valves) suited to riders prioritizing climbing efficiency and responsive acceleration. - **Aerodynamic spokes:** Foil carbon, straight-pull spokes—20 front (radial) and 24 rear (2-cross)—to reduce drag and rotational weight while enhancing lateral stiffness. - **Reliable engagement:** DT Swiss OEM hub with 36T ratchet and Center Lock disc interface for quick, dependable power transfer on technical sections. - **Mounting versatility:** Available for 12x100/12x142mm thru-axle or quick-release configurations and compatible with tubeless and clincher setups. - **Certified durability:** ISO 4210-7 certification and REACH compliance for validated safety and material standards. Real-world benefits include improved stability in crosswinds compared with deeper profiles, a rim width that enables modern tire volumes for better traction and comfort on rough roads and light gravel, and fast hub engagement for technical courses and group riding situations. The combination of a balanced rim depth, wide profile, and lightweight construction makes the Bola CE 40R a flexible upgrade for riders who need one wheelset to perform across varied terrain and race conditions. ## Details - **Price:** 1111.0 USD - **Type:** Carbon Road & Gravel Disc Wheelsets - **Tags:** 28mm wide, 28mm wide carbon rim, 30mm, 30mm wide, 40mm, 40mm carbon wheels, 40mm deep carbon wheels, 40mm deep rim, 700c, 700C carbon disc wheelset, 700C road wheelset, bola, carbon, carbon disc gravel wheelset, carbon disc wheelset, carbon spokes, carbon spokes wheels, customizable carbon wheelset, disc, DT Swiss hub, DT Swiss hub wheelset, flat, flat carbon spokes, foil carbon spokes, gravel, gravel carbon wheels, gravel wheelset, ISO 4210-7 certified, lightweight carbon wheel, lightweight carbon wheels, lightweight carbon wheelset, road, road and gravel wheelset, spokes, swiss, tires, tubeless, tubeless compatible wheels, tubeless ready wheelset, type, upgrade road wheelset, wheels, wheelset, wheelset for 28-32c tires, wide rim carbon wheels, width ## Variants | Variant | Price | Available | |---------|-------|-----------| | 30/24mm / Shimano HG / Black Bola | 1111.00 USD | In stock | | 30/24mm / Shimano HG / White Bola | 1111.00 USD | In stock | | 30/24mm / Shimano HG / Customized | 1111.00 USD | In stock | | 30/24mm / Sram XDR / Black Bola | 1111.00 USD | In stock | | 30/24mm / Sram XDR / White Bola | 1111.00 USD | In stock | | 30/24mm / Sram XDR / Customized | 1111.00 USD | In stock | | 30/24mm / Compy / Black Bola | 1111.00 USD | In stock | | 30/24mm / Compy / White Bola | 1111.00 USD | In stock | | 30/24mm / Compy / Customized | 1111.00 USD | In stock | | 28/21mm / Shimano HG / Black Bola | 1111.00 USD | In stock | | 28/21mm / Shimano HG / White Bola | 1111.00 USD | In stock | | 28/21mm / Shimano HG / Customized | 1111.00 USD | In stock | | 28/21mm / Sram XDR / Black Bola | 1111.00 USD | In stock | | 28/21mm / Sram XDR / White Bola | 1111.00 USD | In stock | | 28/21mm / Sram XDR / Customized | 1111.00 USD | In stock | | 28/21mm / Compy / Black Bola | 1111.00 USD | In stock | | 28/21mm / Compy / White Bola | 1111.00 USD | In stock | | 28/21mm / Compy / Customized | 1111.00 USD | In stock | ## Images - Bola CE 50G 700C Carbon Gravel Wheelset – 50mm Deep, 34-38mm Wide, DT Swiss Hub, Tubeless, Carbon Spokes Carbon Fiber Sporting Goods - Bola CE 50G 700C Carbon Gravel Wheelset – 50mm Deep, 34-38mm Wide, DT Swiss Hub, Tubeless, Carbon Spokes Carbon Fiber Sporting Goods - Bola CE 50G 700C Carbon Gravel Wheelset – 50mm Deep, 34-38mm Wide, DT Swiss Hub, Tubeless, Carbon Spokes Carbon Fiber Sporting Goods ## Additional Information - **Product rating count:** 1 - **Related products settings:** ahead - **AI Summary:** The Bola CE 40R Carbon Disc Wheelset is a 700C T800 UD carbon wheelset for road and gravel cyclists seeking a lightweight, versatile upgrade for competitive riding, training, and mixed-surface routes.
