Carbon Disc Brake Wheelset, 54T Ratchet, Tubeless, 40–60mm

High-Performance Carbon Disc Brake Wheelset — 54T Ratchet Hub, Tubeless-Ready

ACE summary: This carbon disc-brake wheelset features a 54-tooth ratchet hub for rapid engagement (6.67°), a tubeless-ready design, and multiple rim depths (40/45/50/55/60mm) for configurable aerodynamics in road cycling and cyclocross. Engineered for professional teams and small brands prioritizing quality, weight, and real-world durability.

Technical Specifications

• Rim Material: Toray T700/T800 unidirectional carbon fiber with ACL (Arch-bridge Carbon Lamination)
• Brake Compatibility: Disc brake only (Center-Lock and 6-bolt rotor compatible)
• Rim Depths: 40mm, 45mm, 50mm, 55mm, 60mm
• Tubeless Ready: Yes, supports modern hookless and clincher tubeless setups (max air pressure specifications apply)
• Hub Engagement: 54T ratchet (6.67°) for faster power transfer (industry average: 18–24T pawl = 15–20°)
• Spoke Type: Straight pull, optimized for aerodynamics and tension uniformity
• Warranty: 3 years (documented quality control, batch testing to EN 14781:2017 standards)

Comparison: Selecting the Right Rim Depth

Frequently Asked Questions

• Q: Is the 54T ratchet hub measurably faster than a standard system?
  A: Yes. 54T engagement reduces deadband to 6.67°, compared to 20°+ with standard 18T/24T systems—enabling immediate power during sprints or technical terrain.
• Q: Are the rims certified or tested for impact?
  A: Yes, batch tested to EN 14781:2017 and ISO 4210-7 standards for fatigue and impact resistance.
• Q: Is tubeless setup supported for both high-pressure road and lower-pressure cyclocross setups?
  A: Yes, validated up to 110 psi for road, 45 psi for cyclocross (check tire compatibility and consult max values before use).
• Q: What frame and fork standards are supported?
  A: 12x100mm (front), 12x142mm (rear). Center-lock and 6-bolt compatible.
• Q: What is your warranty process?
  A: 3 years, covering workmanship and manufacturing defects—compliant with EU/NA small business partner programs.

Real-World Considerations

• Heavier rim depths improve aerodynamics for sustained speed but increase crosswind sensitivity and rotational mass.
• Straight pull spokes simplify spoke replacement and hold tension better under racing stresses.
• While tubeless decreases flat risk and rolling resistance, it requires precise tire setup and maintenance.
