We are proud to be collaborating with Dom and the team at MASON cycles. A fellow Sussex UK based company who produce some seriously cool bikes and have a shared passion for creating adventure experiences by riding progressive bikes in inspiring places. 

There’s over fifteen years of progressive, award winning design, a passion for style, form and detailing, a love of engineering and making, an obsession with producing the best products, without compromise. A fascination with anything on wheels and a lifetime of riding bikes Dom Mason, Sussex,  2019

2020 sees us collaborate on some exciting cycling trips. We will share our ideas, knowledge and passion with customers and use feedback from their experiences to further progress the evolution of adventure bikes and travel. 

The master team of bikepacking experts at Rpm90 have a collective experience of almost 200 years of riding; their skills have been gained all over the world from the local hills of sussex, to the roads of the Transcontinental race and the high passes of the Silk Road Mountain Race. They have an understanding of provenance and hospitality honed in a background of alpine and fine-dining cheffing. And they operate with an admirable code of sustainable and respectful adventure. This vital combination of skills make Rpm90 the dream partner to collaborate with for our future adventures.” Cal Nicklin, Brand Manager at MASON

MASON InSearchOf 

This radical new adventure bike the ‘InSearchOf’ or ‘ISO’ is a new steel adventure frameset still firmly in the #FastFar, #ContinentCrushing vein. A progressive new frame and fork design allow it to use 29 x 2.4” or 650b x 2.8 wheels, meaning steeper, rougher and deeper terrain are well within it’s capabilities. Multiple mounting points, a bespoke load-bearing mudguard, specific rack systems, 160/180 flat-mount braking and 100mm suspension-ready geometry mean that the InSearchOf, once again, does not shy away from the ‘Progressive’ word in our title.
