Bike info

Radical, modern geometry with a very long reach and a super slack head angle make this bike ideal for anyone who likes to go full gas! This heart of this beautiful 29'er is the amazing steel frame built with custom drawn Tange tubes with built-in gussets. At around 2.4 kg the frame is light by any standards, but don’t worry, it’s strong enough to hold up to a lot of abuse. All the know-how that we have managed to acquire over the years in building steel dirt-jump hardtails has been funnelled into this frame and we are sure it's the very best money can buy. This is really a very unique looking bike and with the dropper post that's included in the package, it rides like a dream both up and down mountains.

 

MAIN FEATURES:
Custom drawn Tange Eccentric cromoly tubes
Radical geo with slack angles
140mm RS Recon fork
SRAM NX 1x12 drivetrain
X-Fusion dropper post
SRAM Level brakes

 

MAIN CHANGES FOR 2019:
SRAM 1x12 drivetrain
Longer wheelbase
X-Fusion dropper post
New lighter fork

Stay true, stay Eccentric! Aggressive modern geometry, very long reach and super slack head angles - the Eccentric bikes are the hardtails of the future.

 

With the big burly 29” wheels you will roll over everything without thinking twice, but at the same time you get the wonderful feeling of being connected with the trail that only a hardtail can provide. You don’t need a full suspension bike to be fast on the climbs and have fun on the downhills! The Eccentric bikes are available in several versions. If you’re looking for a hard hitter, choose between the Cromo and the Alu based on your preferences of frame materials.For typical trail riding, the Lite versions should be more than enough.

 

REVIEWS:

"The NS Eccentric Cromo is an all mountain hardtail with the heart of a dirt jump bike. We love the fact that this bikes wants to be thrown around and changes direction with minimal input." - Singletrack
