700c Carbon Tubular Rim — 40mm Depth, 28mm Outer Width, Offset Optional

Built for serious road and endurance cyclists, this 700c carbon tubular rim blends aerodynamic depth with a wide profile to improve high-speed stability and tyre support. Precision asymmetric construction and Toray carbon layups deliver measured strength and consistent manufacturing tolerances for professional wheel builds. It supports both hooked and hookless tyre interfaces and comes in selectable weight options to match performance priorities.

700c Carbon Tubular Rim — Designed for road and endurance cycling

The 40mm rim depth and 28mm external width are chosen to balance aero performance and wide-tyre aerodynamics, helping riders maintain speed while improving comfort when running broader tubular tyres. Asymmetric drilling reduces left/right spoke tension disparity, enhancing rear-wheel durability and making the rim well suited to high-torque applications and daily training loads.

The construction uses Toray T700 / T800 carbon composite and is manufactured to tight quality standards: forward compressive strength >300kg, lateral torsion >50kg, dynamic balance <3g, flatness <0.15mm, and roundness <0.3mm. Those parameters support reliable wheel build consistency and predictable handling at speed.

Why it fits your routine

• Aerodynamic profile: 40mm rim depth reduces drag for sustained high-speed riding and endurance events.
• Wide tyre compatibility: 28mm outer/inter width accommodates wider tubular tyres for improved traction and compliance on varied road surfaces.
• Asymmetric design: Offset drilling balances spoke tension between drive and non-drive sides to extend wheel life, especially on rear wheels.
• Lightweight options: Available in Superlight (320 ± 10g) and Normal (345 ± 15g) variants to match climbing or durability priorities.
• Precision ERD: Effective Rim Diameter (ERD) 559mm for accurate spoke length calculations during wheel builds.
• Tyre and pressure compatibility: Designed for tubular tyres with maximum hooked tyre pressure rated to 125 psi.
• Pro-level materials and testing: Toray T700 / T800 carbon composite and measured structural benchmarks support professional and OEM use.
• Build flexibility: Custom drilling and weight options enable tailored wheel builds for team, OEM, or high-spec aftermarket assemblies.
• Warranty: 3-year structural defects warranty covers manufacturing-related issues for rider confidence.

Technical summary: 700c (ISO 622) U-shape rim, 40mm depth, 28mm outer and internal width, ERD 559mm, tubular tyre only, weight 320–345g depending on option, max hooked tyre pressure 125 psi, Toray T700/T800 carbon, 3-year structural warranty. These specifications make the rim a practical upgrade for riders seeking an aerodynamic yet wide-platform tubular rim that integrates into professional wheel builds and endurance-focused setups.
