10 OUT OF 10!

Cycling Weekly have put the new Mason InSearchOf (ISO) through its paces in the South Downs National Park, a gem for bikepacking and adventure cycling. With a huge variety of terrain and riding styles, a multi-terrain adventure machine such as the ISO can conquer it all.

After several weeks of demanding testing in all conditions and on both wheelsets - 27.5+ and 29" - Paul Norman concludes:

"...the Mason ISO is a supremely competent ride if you’re wanting to tackle more radical terrain on a drop bar bike, either for a quick outing or a longer, multi-day trip. It gives the stability and confidence to keep riding through, over, up and down whatever gets in your path."
 

Paul Norman is an experienced MASON rider by now, having ridden and reviewed every model. But, this is the first time he's ever given the 10!

"The astonishing thing about the ISO is just what you can tackle when riding it. So wet, muddy or compacted chalk uphills which would have defeated me on just about anything else I could just roll up on the Mason ISO."

...there’s a choice of Hunt wheelsets: the TrailWide 650b wheels boast 30mm internal width rims while the equally wide Mason x Hunt The Search 700c wheels come with the option of a front hub dynamo for an extra £150. There’s internal routing through the fork leg for the dynamo cables.

That choice hints at the Mason ISO’s other life. It’s a bike designed not only for the weekend warrior in search of more extreme terrain, but the confirmed bikepacker looking to take on fully loaded off-road adventures.

"So the Mason ISO is a supremely competent ride if you’re wanting to tackle more radical terrain on a drop bar bike, either for a quick outing or a longer, multi-day trip. It gives the stability and confidence to keep riding through, over, up and down whatever gets in your path."
