What to Compare Before Buying

  • Wheel size: This fork is for 20 inch 4.0 fat tire bikes. Compare that size against your bike’s front wheel setup.
  • Axle standard: The stated 9×135 mm QR setup needs to match the front hub and dropouts on the bike.
  • Brake type: Disc brake compatibility is stated, so confirm your brake system matches.
  • Travel and geometry: The stated 180 mm travel affects front-end height and fork fit, so compare it with your frame and riding position.

When to Consider a Different Option

Choose a different fork if your bike does not match the stated 20 inch 4.0 size, 9×135 mm QR setup, or disc brake requirement. A different fork is also worth considering if you need a different travel amount or a different adjustment style.

Before You Decide

Confirm the 20 inch 4.0 fit, the 9×135 mm QR axle setup, and the disc brake requirement before choosing this fork. If your bike uses a different front-end standard, select a fork built for that exact setup.
