I am selling my son's 2021 Kona Fire Mountain. It is a great hardtail with a lot of life left, but he has out grown it. I have made a few upgrades to the bike, including: 100mm ROCKSHOX air fork, 120mm TranzX dropper post, brand new drivetrain (bottom bracket, crankset, and a new chain), race face chester pedals, fifty fifty grips (these are close to worn out). Tires are now Maxxis Minion DHR in the front and a WTB trail tire in the rear. Here are some more details on the bike: https://archive.konaworld.com/archive/2021/fire_mountain.cfm
