700c Asymmetric Carbon Clincher Rim — 38mm Depth, 25mm Wide

Answer: Precision-engineered for demanding cyclists, this 700c asymmetric carbon clincher rim combines a 38mm aerodynamic depth with a 25mm external width to maximize spoke tension balance and wide-tyre aerodynamics. Compatible with both hookless and hooked clincher tires, it supports tubeless and tube-type setups, with a weight range of 385–425g depending on option.

Context: Targeted for premium road and endurance cycling wheel builds, asymmetric drilling reduces spoke tension disparity, enhancing wheel durability—particularly for rear wheels. Built from tested Toray T700 / T800 composite, it meets advanced structural performance benchmarks (Forward Compressive Strength >300kg; Lateral Torsion >50kg; Dynamic Balance <3g; Flatness <0.15mm; Roundness <0.3mm) for professional and brand-level use.

Frequently Asked Questions

  • Q: What are the advantages of an asymmetric 700c carbon rim?
    A: Improves spoke tension balance for increased durability and reliability, especially for rear wheel builds.
  • Q: How does hookless vs. hooked compatibility affect tire setup?
    A: Hookless is preferred for tubeless with lower pressures; hooked supports higher pressures and standard clinchers.
  • Q: Is this rim suitable for endurance or racing wheel builds?
    A: Yes, optimally tested for both applications. Choose weight options based on use-case priorities.
  • Q: What is the recommended tyre size?
    A: Best performance with 25–32mm wide road tires, both tubeless and tubed.
  • Q: Are custom drilling/hole patterns available?
    A: Yes, to suit various spoke types and lacing patterns for professional wheel builders.
