2021 kona Fire Mountain
Manufacturer Description
This Kona classic brings some of the finer things to light. The Fire Mountain is running a smooth-shifting 9-speed drivetrain to keep things manageable across varying terrain and hydraulic disc brakes to stop on a dime. With 100mm of adjustable suspension and sturdy tires aboard wider 27mm rims, the Fire Mountain helps build confidence off-road. Available for smaller riders in a 26” wheeled XS version and a 27.5” wheel for sizes S-XL.
