VERSATILE FREERIDE FRAME FOR ALL-OUT RIDING
The Surge Evo is a proven frame that’s been pushed to the limit by riders worldwide. Originally designed as a dedicated freeride hardtail, it’s evolved into an all-around shredder—perfect for aggressive trail riding, dirt jumps, and even longer, more technical rides.

It accommodates your favorite dropper post and fits forks with either standard 1 1/8” or tapered 1.5–1 1/8” steerer tubes. Whether you’re ripping down freeride lines or sessioning the jump park, this frame is built to handle it all.
