27.5" Asymmetric Carbon MTB Rim – 30mm High, 27mm Internal Width

Summary: Lightweight, durable carbon rim for cross-country (XC) and all-mountain (AM) riders needing balanced strength, weight, and handling. Choose Standard (430 ± 15g) or Superlight (365 ± 10g) build. Asymmetric spoke bed optimizes tension, reducing wheel fatigue and improving lateral stiffness on technical terrain.

Key Features

  • Rim Size: 27.5" (650B) for modern XC & all-mountain bikes
  • Profile: 30mm depth, 27mm internal width, 33mm external width – maximizes tire stability for 2.2"–2.6" tires
  • Construction: High-modulus carbon fiber (T700/T800 grade), U-shape hookless, tubeless-ready
  • Weight: Standard 430g ± 15g / Superlight 365g ± 10g
  • Asymmetric spoke hole drilling: Reduces peak spoke tension difference between drive/non-drive sides for improved longevity
  • Strength: Forward Compressive >300kg, Lateral Torsion >50kg (internal test standards)
  • Custom options: Spoke count, valve type, drilling angle
  • Certifications: Dynamic Equilibrium <3g out-of-round (internal), 3-year limited warranty

Frequently Asked Questions (FAQ)

  • Is a 27mm inner width carbon rim suitable for aggressive all-mountain riding?
    Yes, 27mm inner width supports wider tires (2.2"–2.6"), improving sidewall support and grip on technical and aggressive terrain.
  • What is the weight difference between Standard and Superlight models?
    Superlight: 365 ± 10g; Standard: 430 ± 15g. Weight difference: approximately 65g per rim, impacting acceleration and climbing ease.
  • Why choose an asymmetric carbon rim?
    Asymmetric geometry offsets spoke holes, balancing spoke tension and enhancing wheel durability in high-stress riding.
  • Are there carbon 27.5 rims under 400g for XC racing?
    Yes, the Superlight variant at 365g is optimized for competitive XC use and meets sub-400g requirements.
  • How does your 27.5" rim compare to other leading carbon XC rims?
    This rim offers a balance of high lateral/torsional strength, modern internal width, and verified test metrics matching peer review standards for EU/NA brands.
