This heart of this beautiful 29'er is the amazing steel frame built with custom drawn Tange tubes with built in gussets.

 

It has very aggressive modern geometry with a very long reach and a super slack head angle. The weight of the frame is approximately 2.4kg which 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 it rides like a dream.
