Amazon.com : ZTZ 26/27.5/29 inch MTB Dual Air Suspension Fork, 1 1。Wholesale Air Suspension 27.5/29 Inch MTB Mountain Bike Fork。Wholesale Air Suspension 27.5/29 Inch MTB Mountain Bike Fork。Wholesale Air Suspension 27.5/29 Inch MTB Mountain Bike Fork。I bought this on an e-commerce site. I used it only once to ride my MTB right after it arrived, but then I immediately removed it and put it back in the box. The AIR caps are blue, and the AIR suspension is mainly black and gold. It's for 29 inches, but I think 27.5 will also fit. All bearings are included, so you can ride it right away.
