The Breezer Thunder is a fully rigid steel all terrain bike that will become your go-to bike. When Joe Breeze designed the original Thunder, his idea was to make a bike that had a 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 the soulful ride quality and durability of steel, the new frame features a fully-butted chromoly frame with tapered headtube, field-serviceable external derailleur and brake routing, internal dropper seatpost routing, and a multi-mount system in the front triangle to allow for installation of bottles and half-frame bags.
