A beautiful yet tough hardtail frame for all mountain and trail riding. We built this frame using Tange Eccentric cromoly tubes that have been developed over the years for our 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 our in depth knowledge of steel frame constructions we 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.
For 2015 the geometry has been tweaked and the frames are now slightly longer. We also added a hole for stealth cable routing.

Note on sizing: we recommend the S size for riders up to 172cm, M size for 170 – 182cm and the L size for riders over 180cm.
Always wear a helmet when riding. It will not make you deathproof, but will increase your chances to avoid serious injury if you crash (and you WILL crash). A broken leg can be fixed. A broken brain cannot ! Even if you see some of our riders without a helmet, it's only because they are complete idiots !
