NS Bikes Eccentric Cromo Frame

A beautiful yet tough hardtail frame for all mountain and trail riding. NS built this frame using Tange Eccentric chromoly tubes that have been developed over the years for their dirt-jump bikes.

The result is an incredibly strong yet light hardtail for aggressive trail riding. The Eccentric is designed primarily for 650B wheels but will work with 26” too. Rides best with a 140-150mm fork. The weight of the frame is approximately 2.4kg which is light by any standards, but thanks to their in depth knowledge of steel frame constructions NS know that it will also be strong enough to hold up to a lot of abuse. All the know-how that NS has managed to acquire over the years in building steel hardtails has been funnelled into the frame of this bike and it really is the very best money can buy.
