Confidence at speed

Race on Sunday, ride on Monday. The Fourstroke is now longer and slacker to provide maximum confidence on whether you’re elbow-to elbow between the tapes or elbows-out on your favorite singletrack.

Marathon ready

When you’re in for the long haul there’s space for two water bottles within the Fourstroke’s frame. Perfect for marathons, training rides and all-day adventures.

Tire check

With room for up to 2.4” XC tires, the Fourstroke’s frame has ample mud clearance and enough room to fit the right tread for the terrain.

Precision engineered

We’ve focused on the details so you can focus on the ride. Fully guided cable routing and chainstay protection keep noise to a minimum and a rotation-limiting headset prevents damage to the frame when things go sideways.
