Thunder
Description
When Joe Breeze designed the original Thunder, his idea was to make a bike that had geometry and components that allowed riders to explore the remote trails and hillsides of Northern California and beyond. That spirit lives on with the new Thunder. Still constructed with soulful ride quality and durability of steel, the new frame boasts some major advancements to allow adventure riders to explore deep into the woods outside of town or on the other side of the world.
Features

• Field- serviceable external derailleur and brake routing
• Internal dropper seatpost routing
