The Surge is a great all round frame for anyone who likes to go hard in all kinds of conditions. It's a pure freeride hardtail with a slack head angle and lower bottom bracket. Perfect for new school freeride, yet at the same time comfortable on longer rides and great for dirt jumping. We believe that steel is the best material for this kind of frame giving the bike a great feel and making it absolutely bombproof.
It will work correctly with 120 – 160 mm forks and 650B or 26” wheels.
For 2015 the frame is compatible with a 30.9 seatpost which means you can fit your favourite dropper post easily.
