Lightweight Mechanical Formed 6061-T6 Aluminium Frame 
A lightweight 6061-T6 aluminium frame provides a bombproof chasis for trail centre assaults with great upgrade potential for fitting a chainguide thanks to the ISCG tabs.
Our aggressive trail geometry has been designed around 29” wheels and a 100mm travel fork; a short headtube and low bottom bracket keep the centre of gravity low to provide improved handling whilst the larger wheel size offers improved performance and handling.
