After several weeks of riding, I’m still not entirely sure what to make of Mason’s ISO adventure/gravel bike. I've tested a few of the best gravel bikes over recent years and they've all been pseudo race bikes. Light weight carbon frames, v-section carbon wheels and a dialled in ride position similar to the road bikes I get to ride.
The ISO 2 is none of these things, and proudly so. This is a bike made for long-haul adventure. Ready to be loaded up and ridden far and wide over any terrain. An Italian-made steel frame with chunky 29” tyres, a ton of clearance and covered in mounting points - from the outset, this bike was always going to be a little bit different.
