Something radical from Mason Cycles: the new ISO

A drop bar steel bike to tackle steeper, tougher terrain, snow and sand

The new Mason ISO is designed to take you further off road, while still allowing you to ride further and faster. The ISO’s frame and fork have the clearance for 2.4 inch 700c tyres or 2.8 inch 650b. That’s a serious amount of rubber, letting you tackle steeper, rougher, deeper terrain.

It’s a gear up in off road capability from Mason’s Bokeh all-terrain machine.
