OUR STEEL ULTIMATE ADVENTURE BICYCLE
The NEW ISO2 is here.
When we launched the MASON InSearchOf in 2019, we rewrote the book on long-haul adventure bicycles. As a drop-bar machine borrowing freely from gravel, mountain bike and touring disciplines, the InSearchOf has enabled incredible journeys that span continents. After six years and millions of kilometres, the InSearchOf has earned a refresh with refinements and additions that combine into a new version we're calling the ISO2.
The core details live on from the InSearchOf to the new ISO2:
- Custom-formed progressive-butted Dedacciai Zero and Reynolds 853 steel
-
Handbuilt in Italy
-
Choice of 29” or 27.5" wheels
-
29 x 2.6” or 27.5 x 2.9” tyre clearance
-
Suspension-fork compatibility, with corrected geometry
-
Boost spacing, for the stiffness and strength of mountain bike hubs
The new ISO2 adds...
-
T47 bottom bracket, for maximum stability
-
Revised routing to protect cables and hoses
-
Top tube mounts for simple equipment attachment
-
MASON HotShoe2 carbon fork, with optimised details and repositioned equipment mounts
-
MASON-designed CNC dropouts, with Universal Derailleur Hanger compatibility
If you are looking to tackle more extreme off-road, while still having the ability to roll along comfortably on tarmac, or if you plan some serious bikepacking expeditions, it lets you go further and more extreme than just about any other drop bar bike.
