RIDEDRIVENDESIGN: Defining the All-Road Bike
Introducing the Definition 3.0, the latest iteration of our iconic series, further refining what a performance all-road bicycle should be. Building on the acclaimed legacy of its predecessors, we’ve implemented thoughtful enhancements to elevate your riding experience, all while staying true to our #RideDrivenDesign ethos. This bike embodies the very definition of an all-road machine, configurable with Shimano, SRAM, or Campagnolo groupsets to meet your precise needs.
The Definition has always stood apart as a sporty, all-season, all-road marvel, and now, it’s evolved even further. Previously lauded by road.cc as ‘A masterclass in bike design and engineering’ and ‘Phenomenal’, this latest version is meticulously optimized for speed and adaptability across varied surfaces and long-distance journeys. It truly sets a new Bike Definition for the discerning cyclist.
Sharing the foundational geometry with our Columbus steel Resolution, the Definition is engineered to deliver a sportier feel while upholding the renowned MASON hallmarks: engaging handling, enduring comfort, and unwavering dependability. For those seeking a clear bike definition in aluminum, the Definition 3.0 provides an exemplary answer.
The heart of this machine is its premium Dedacciai aluminum frame, a powerhouse of pedaling efficiency and power transfer. Its lightweight construction, coupled with custom-shaped MASON x Dedacciai stays and a large diameter downtube, results in a ride that is both punchy and remarkably responsive. This is how we define a high-performance aluminum bike.
Since their inception, we have continuously refined both the Resolution and Definition, adapting and improving with each iteration. However, the core geometry and intended purpose remain unchanged. The Definition and Resolution pioneered a new category, and they continue to lead in a class of their own. This latest evolution of the Definition incorporates key changes and new features, specifically aimed at enhancing its capabilities for the long-distance, all-season riding for which it is already celebrated. Our ‘Ride Driven Design’ mantra serves as our guiding principle, informed by invaluable feedback from our riders and customers since the original Definition launched in 2015. This journey has been marked by continuous improvements, updates, and new versions, each step forward refining the bike definition.
Throughout this evolution, we’ve been meticulous in preserving the essential qualities that made the original MASON Definition so exceptional: its magic, refinement, dependability, engaging character, and confidence-inspiring performance, all year round. This is our unwavering bike definition, continuously honed for the ultimate riding experience.
