700c Carbon Tubular Rim — 45mm Depth, 28mm Outer Width, Asymmetric Options

Designed for fast road miles and endurance days in the saddle, this 700c carbon tubular rim pairs aerodynamic depth with a wide 28mm profile to improve tyre contact and handling. Precision-engineered for hub builders and pro-level wheel builds, it balances low weight with structural strength for long rides, group efforts and race-day demands.

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

This rim brings a measured combination of aerodynamic performance and tyre-friendly width. The 45mm rim depth reduces drag at speed while the 28mm external width supports wider tubular tyres for improved traction and shock absorption. Offered in asymmetric (offset) or metric drilling to reduce spoke tension imbalance, the rim is targeted at rear-wheel or custom OEM builds where durability and balanced tension matter most.

Riding feel improves as the wider profile smooths small bumps and provides greater tyre volume for controlled cornering and confidence on mixed road surfaces. Lightweight options (330 ±10g superlight; 355 ±15g normal) let builders prioritise acceleration or durability without sacrificing consistent handling at pace.

Why it fits your routine

• Aerodynamic depth: 45mm profile tuned to reduce drag for sustained high-speed riding and endurance events.
• Wide tyre compatibility: 28mm outer width accommodates wider tubular tyres to increase traction and ride comfort while improving crosswind behavior when matched to tyre choice.
• Asymmetric/metric drilling: Optional offset spoke drilling reduces spoke tension disparity for stronger rear-wheel builds and longer service life.
• Lightweight construction: Choice of superlight (≈330g) or normal (≈355g) builds to suit race or training priorities.
• Precision materials: Constructed from Toray T700 / T800 carbon composite for a balance of stiffness and impact resistance.
• Measured performance: Manufactured to meet structural benchmarks including forward compressive strength >300kg, lateral torsion >50kg, dynamic balance <3g, flatness <0.15mm and roundness <0.3mm.
• Compatibility: ISO 622 (700c) diameter with 549mm ERD and tubular tyre fit; supports hooked and hookless tubeless-compatible tyre types when used in appropriate configurations.
• Pressure rating: Maximum tyre pressure for hooked setup up to 125 psi.
• Warranty: Includes a 3-year structural defects warranty for peace of mind in professional and enthusiast use.

Technical specifications include 700c (ISO 622) diameter, U-shaped rim profile, 45mm depth, 28mm external and internal width, ERD 549mm, and material specification Toray T700 / T800 carbon composite. Weight options and custom drilling choices support OEM and pro-team wheel builds where tailored spoke counts and balance are required. These characteristics make the rim suitable for endurance road racing, wide-tyre road setups and bespoke wheelbuilding projects where aerodynamic efficiency, tyre support and long-term durability are priorities.
