Who is the Merida Big.Nine 400 designed for?

The Big.Nine 400 is a great choice for riders looking for a less aggressive position and more comfort and control, as its geometry sits riders in a more upright position. Its 1x11 gearing also suits riders looking for a higher top speed on flat terrain.
