Frequently Asked Questions

• Q: Is a 25mm inner width sufficient for technical enduro riding?
  A: Yes. 25mm inner widths deliver optimal support for 2.3–2.6" enduro tires, balancing responsive handling and puncture resistance at lower pressures.
• Q: What advantage does a 30mm profile bring?
  A: Enhanced lateral stiffness for sharper cornering, proven by comparative tests with 23.5–26mm profile rims.
• Q: How does this rim compare to 31-32mm internal competitors?
  A: Offers lighter weight while providing reliable tire stability for most enduro/all-mountain use. 31-32mm may be better for plus-size tires (>2.6").
• Q: What is the maximum recommended rider weight?
  A: Lab-tested for up to 120kg rider+bike weight.
• Q: Is this rim compatible with both tubeless and tube setups?
