700c Carbon Tubeless Rim — 50mm Depth, 30mm Outer Width, Ultralight Options for Road & Gravel

Hit a long rolling route, chase a crit PR, or build a lightweight gravel grinder with rims tuned to real-world demands. These 700c carbon tubeless rims combine a 50mm asymmetric V-profile with a 30mm outer / 24–25mm inner width to balance aerodynamics, tyre support, and climbing efficiency across four verified weight tiers.

700c Carbon Tubeless Rim - Designed for road and gravel performance

The generous 30mm outer width stabilises 25c–32c tubeless tyres for a more stable contact patch and improved cornering confidence, while tubeless compatibility and a hookless-friendly bead seat enable lower tyre pressures for added comfort and traction on mixed surfaces.

Riders will feel the tradeoff between aero gains and rotating mass: the 50mm profile offers tangible drag reduction at higher speeds, and the selectable weight tiers let you prioritise durability or minimal mass depending on your race or training goals.

Why it fits your routine

• Performance-tuned profile: 50mm asymmetric V-shape provides aerodynamic advantage at sustained speeds above ~35 km/h while maintaining lateral stiffness for responsive handling.
• Wide tyre compatibility: 30mm outer / 24–25mm inner width supports tubeless tyres from 25c to 32c, optimising tyre profile for lower pressure, better grip, and reduced rolling resistance compared with narrower rims.
• Four verified weight tiers: Choose Normal (475g ±15g), Superlight (435g ±10g), Ultralight (405g ±10g), or Extreme Light (380g ±10g) to match rider mass and intended use, from durable training to race-day builds.
• Structural reliability: Forward compressive strength >300 kg, lateral torsion >50 kg, and spoke hole tension >280 kg provide robust load handling for daily use and spirited efforts.
• Precision manufacturing: Dynamic equilibrium <3g imbalance, flatness tolerance <0.15mm, and roundness tolerance <0.3mm support consistent wheelbuilding and predictable ride feel.
• Customisable details: Valve hole (6.5mm), spoke hole (4.5mm), and assembly hole (7.5mm) diameters plus nipple offset and valve specifications can be customised to fit wheelbuilder preferences.
• Practical limits: Tyre pressure range 100–125 psi and maximum rider weight 120 kg; Extreme Light tier is optimised for riders under ~75 kg on smooth roads.

Technical measurements important to builders: ISO 622mm diameter, ERD 538mm, available inner widths of 24mm or 25mm (specify at order), and a valve hole diameter that can be customised; these rims are built for tubeless setups and wheelsets targeting sub-1,400g with the lighter tiers.
