# Bola ULT 50R 700C Carbon Disc Wheelset — 50mm Toray T800, Tubeless-Ready, 1250g Clip into the pedals and feel the difference on a long group ride or a mixed-surface adventure: the Bola ULT 50R 700C wheelset blends a 50mm aerodynamic rim profile with a lightweight 1250g set weight to help you maintain speed with less effort. Built for riders who split time between road and gravel, these wheels are tubeless-ready and engineered to balance acceleration, stability, and long-ride comfort. ## Bola ULT 50R 700C Carbon Disc Wheelset - Designed for road and mixed-surface endurance The mid-profile 50mm rim delivers aerodynamic gains without the extreme handling trade-offs of deeper rims, making it suitable for fast group rides, endurance road events, and gravel routes where predictable crosswind behavior matters. Toray T800 unidirectional matte carbon construction provides a high strength-to-weight ratio that supports reduced rider fatigue over hours in the saddle, while the tubeless-ready design lets you run wider tires at lower pressures for added traction and comfort on rougher surfaces. ### Why it fits your routine - **Aerodynamic yet manageable:** 50mm rim depth balances aero efficiency and crosswind stability for road speed without sacrificing control on mixed surfaces. - **Modern tire support:** Internal widths of 21mm or 24mm with external widths of 28mm or 30mm accommodate 28–48mm tubeless tires, enabling lower pressures for comfort and grip. - **Lightweight performance:** 1250g wheelset weight reduces rotational mass to improve acceleration and sustain higher speeds with less energy expenditure. - **High-quality construction:** Toray T800 unidirectional carbon rim paired with Sapim CX-Ray stainless spokes and a 2-cross lacing pattern for a responsive, reliable ride feel. - **Precision hubs and bearings:** BL1 alloy hub with 54T engagement and TPI ceramic bearings for efficient power transfer and consistent performance. - **Disc-specific safety and compatibility:** Disc brake design with 12x100/12x142mm axle or QR compatibility, ISO 4210-7 and EN-tested for validated durability. - **Tubeless-ready versatility:** Ready to run modern tubeless setups for improved puncture resistance and ride comfort across pavement and gravel. - **Durability and support:** 24-month limited global warranty backing construction and testing standards. These wheels are intended for riders upgrading from alloy wheels to carbon disc systems who want one versatile wheelset for both fast road use and mixed-surface adventures. The combination of a mid-depth rim, modern rim widths, and tubeless capability means you can tailor tire choice and pressure to the terrain while relying on a tested carbon layup and robust hub system. Whether your priority is cutting seconds on group rides, reducing cumulative fatigue on long endurance days, or using a single wheelset across road and gravel, the Bola ULT 50R presents a balanced engineering package that focuses on efficiency, reliability, and comfort. ## Details - **Price:** 698.0 USD - **Type:** Carbon Road & Gravel Disc Wheelsets - **Tags:** 28mm wide, 30mm wide, 50mm, 50mm carbon rims, 50mm rim depth, 50mm rim depth wheelset, 700c, 700C carbon disc wheelset, 700c disc brake wheels, 700C disc wheelset, 700C road bike wheels, aero carbon wheels, aero carbon wheelset, aero road wheels, aero wheelset, carbon bike components, carbon disc wheelset, carbon wheelset, center lock disc brake wheels, ceramic bearing hub, disc, endurance cycling, gravel bike wheelset, gravel cycling wheels, gravel wheelset, gravel wheelset 1250g, ISO certified, ISO EN tested, lightweight carbon wheels, lightweight carbon wheelset, lightweight road bike wheels, road, road bike upgrade, road bike wheel upgrade, Sapim CX-Ray spokes, Toray T800, Toray T800 carbon rim, Toray T800 rim, tubeless, tubeless bike wheels, tubeless ready carbon wheels, tubeless ready wheels, tubeless ready wheelset, tubeless-compatible, ult, wheels, wheelset ## Variants | Variant | Price | Available | |---------|-------|-----------| | 28/21 mm / Shimano HG / Black Bola | 698.00 USD | In stock | | 28/21 mm / Shimano HG / White Bola | 698.00 USD | In stock | | 28/21 mm / Shimano HG / Customized | 698.00 USD | In stock | | 28/21 mm / Sram XDR / Black Bola | 698.00 USD | In stock | | 28/21 mm / Sram XDR / White Bola | 698.00 USD | In stock | | 28/21 mm / Sram XDR / Customized | 698.00 USD | In stock | | 28/21 mm / Compy / Black Bola | 698.00 USD | In stock | | 28/21 mm / Compy / White Bola | 698.00 USD | In stock | | 28/21 mm / Compy / Customized | 698.00 USD | In stock | | 30/24 mm / Shimano HG / Black Bola | 698.00 USD | In stock | | 30/24 mm / Shimano HG / White Bola | 698.00 USD | In stock | | 30/24 mm / Shimano HG / Customized | 698.00 USD | In stock | | 30/24 mm / Sram XDR / Black Bola | 698.00 USD | In stock | | 30/24 mm / Sram XDR / White Bola | 698.00 USD | In stock | | 30/24 mm / Sram XDR / Customized | 698.00 USD | In stock | | 30/24 mm / Compy / Black Bola | 698.00 USD | In stock | | 30/24 mm / Compy / White Bola | 698.00 USD | In stock | | 30/24 mm / Compy / Customized | 698.00 USD | In stock | ## Images - Bola ULT 50R 700C Carbon Disc Wheelset – 50mm, 21/24mm Inner, Tubeless Ready, 1250g Carbon Fiber Sporting Goods - Bola ULT 50R 700C Carbon Disc Wheelset – 50mm, 21/24mm Inner, Tubeless Ready, 1250g Carbon Fiber Sporting Goods - Bola ULT 50R 700C Carbon Disc Wheelset – 50mm, 21/24mm Inner, Tubeless Ready, 1250g Carbon Fiber Sporting Goods ## Additional Information - **Product rating count:** 11 - **Related products settings:** ahead - **AI Summary:** The Bola ULT 50R 700C Carbon Disc Wheelset is a Toray T800 carbon wheelset for road and gravel cyclists seeking a lightweight, tubeless-ready disc-brake setup for fast road riding and mixed-surface routes.
