# 700c Carbon Tubular Rim 50mm Depth 28mm Width — Asymmetric or Metric Race and endurance riders seeking a balance of aerodynamic depth and wide-tyre stability will notice the difference from the first wheel build. This 700c carbon tubular rim is engineered to deliver predictable spoke tension balance and a planted feel when paired with modern wide tubular tyres. Precision internal moulding and choice carbon layups make this rim suited to high-mileage training, long solo efforts, and team-level wheel builds where durability and consistency matter. ## 700c Carbon Tubular Rim 50mm Depth 28mm Width - Designed for road and endurance cycling This rim pairs a 50mm aerodynamic rim depth with a 28mm external/interior width to support wide tyre profiles without sacrificing stability. Asymmetric drilling reduces spoke tension disparity across the hub, improving rear-wheel durability and helping maintain true over extended use. Built from Toray T700 / T800 carbon composite, the rim is produced to meet rigorous structural benchmarks: forward compressive strength >300kg, lateral torsion >50kg, dynamic balance <3g, flatness <0.15mm, and roundness <0.3mm. Mood and ride feel: riders report a composed high-speed sensation when wheels are built around a balanced rim like this one — deeper aero performance with the tyre volume to smooth road irregularities while keeping confident cornering response. ### Why it fits your routine - **Aerodynamic advantage:** 50mm depth reduces drag on sustained efforts and improves high-speed efficiency for road and endurance use. - **Wide-tyre compatibility:** 28mm external/inter width supports modern wider tubular tyres for improved comfort and traction. - **Spoke tension balance:** Asymmetric or metric drilling options reduce tension differences between drive and non-drive sides, enhancing rear-wheel durability. - **Lightweight choices:** Available in Superlight (approx. 350 ± 10g) and Normal (approx. 375 ± 15g) variants to match weight and strength priorities for race builds or robust training wheels. - **Precise fit:** Effective Rim Diameter (ERD) 539mm simplifies spoke length calculations for accurate wheelbuilding. - **Proven materials:** Constructed from Toray T700 / T800 carbon composites for a performance-focused stiffness-to-weight ratio. - **Pressure rating (hooked):** Maximum tyre pressure up to 125 psi when used with hooked tyre systems per specification. - **Warranty:** 3-year structural defect warranty supports long-term use in team or personal builds.
