Lightweight Durability
With a durable Tectonic® T1 aluminum frame, the fireball is ready for any dirt jumps or big-wheeled street riding you can throw at it. The tapered headtube allows for easy fork upgrades.
Fork in the Path
The RST Dirt T suspension fork with 100 mm of travel soaks up the hard landings that come with an appetite for big air.
Stopping Power
Mechanical disc brakes deliver reliable stopping power. Long brake housing allows for bar-spins straight out of the box.
Get in Gear
The simple 1x9 drivetrain is tuned for climbing, with enough range to keep rowdy street riding fun. It's all uphill and mid-air from here.
