Do you like fun? This is the hardtail for you.

The revamped Pedalhead maintains its spirit as the adventure hardtail, built for everything from crushing singletrack miles to getting rad around town.

Inspired by the modularity on our full suspension bikes, swappable dropouts allow riders to switch between a geared and single-speed setup. Designed and engineered in house, this proprietary system allows you to seamlessly convert your geared bike into a single-speed rig. The refreshed custom steel tubing retains its unique square profile. The tubeset combines lateral frame stiffness for cornering and power transfer with vertical compliance to take the edge off of trail chatter.

The Pedalhead has the characteristic “GG-style” geometry, built for goin’ fast and having fun no matter where you find yourself. From the gnar to the bar, the Pedalhead is your go to adventure bike.
