Compatibility, Size and Fit
This fork is built around a 20 inch folding bike format and uses QR 9x100mm spacing. It also lists a 28.6 mm threadless straight steerer tube. Those are the main fit points to compare with your frame, wheel, and headset before buying.
The listed disc brake use and 2.5″ maximum tire size are also important. If your current setup uses rim brakes, a different fork type is needed.
