Forks

Choosing the Right Mountain Bike Fork

The fork dictates how your bike handles rough ground, how much confidence you have in corners, and how tired your arms get on longer rides. Getting the right one matters more than almost any other component choice.

Compatibility Checklist

Before buying, confirm these four specs match your frame:

• Wheel size: 27.5”, 29”, or mullet-compatible. Most modern forks are wheel-size specific.
• Axle standard: Boost 110x15mm is now standard on almost everything. Older bikes may use 100x15mm or 9mm QR.
• Steerer tube: Tapered (1.5” to 1-1/8”) fits most modern frames. Straight 1-1/8” steerers are still common on older and budget bikes.
• Travel: Stay within 10–20mm of what the frame was designed for. Overlonging a fork slackens the head angle and raises the bottom bracket, which changes handling more than people expect.

Popular Fork Ranges

• Fox 34 / 36 / 38: The benchmark. 34 for trail, 36 for enduro, 38 for gravity. GRIP2 and FLOAT dampers.
• RockShox Pike / Lyrik / ZEB: The direct competitors. Pike for trail, Lyrik for enduro, ZEB for big travel. Charger damper platform.
• Marzocchi Bomber Z2 / Z1: Fox-owned, same internals, lower price. Excellent value on the used market.
• DVO Diamond / Sapphire: Small-batch quality with off-the-shelf damper tuning that suits heavier riders out of the box.
• SR Suntour Auron / Durolux: Budget-friendly forks that punch above their weight, especially the Durolux EQ.
