Quick Summary
The ZTZ MTB dual air suspension fork is a front fork for mountain bikes with 26, 27.5, and 29 inch wheel size options. It uses a 1 1/8 straight tube, 120mm travel, QR 9mm x 100mm spacing, and manual lockout. Those are the main details to compare before choosing a variant.
If you are looking at this fork for an XC or AM mountain bike setup, the key checks are wheel size, steerer type, axle spacing, and whether the fork matches your bike’s front-end configuration.

Compatibility, Size and Fit
This fork is the kind of part where exact fit matters more than general appearance. The wheel size, straight 1 1/8 steerer, 120mm travel, and QR 9mm x 100mm front spacing all need to line up with the bike you plan to use it on. If any of those points do not match, choose a different version.
Before You Decide
Confirm the wheel size, 1 1/8 straight tube, QR 9mm x 100mm spacing, and 120mm travel before choosing an offer. Manual lockout is part of the listed configuration, so make sure that matches your preferred setup.
