NS Bikes Surge Evo Frame

If you want to go hard in all conditions, choose NS Bikes' Surge Evo Frame. It's a no nonsense hardtail frame for those who want to switch between freerides, weekend dirt jumping, or longer all-day rides. The Surge Evo Frame is strong, comfortable, and durable to meet all of your versatile riding needs.


Made from custom-butted 4130 CrMo, the Surge Evo Frame provides superior strength and durability, which means it can handle plenty of action. The lower bottom bracket and slack angled headtube offer a balanced geometry to make this hardtail frame truly versatile as well as bombproof.

Updated for the new season, the Surge Evo Frame now has rubber grommets for improved internal cable routing.


NS Bikes' Surge Evo Frame comes with a 30.9mm seatpost diameter, which means you can install the dropper post of your choosing for customised comfort and performance.
