An english acronym for a bike whose roots lie as much in the wild years of french « Constructeurs » and « concours de machine » as in the Rough Stuff Cycling of Fred Wright. A modern randonneur bike, very capable, sporty and versatile.

Fourth iteration of our prototypes development, our All-road bike kept this number in his model name. Build from high end heat treated steel tubing, paired with a modern carbon fork, our MR4 is the perfect base for a light and performant build.

Even if we don’t have any bed feelings about carbon, aluminium or titanium, steel is for us the best frame building material. Easy to work with, very predictable, steel and its latest developments allow the creation of performant and durable bikes, only a tad heavier than their other material counterparts and with a timeless aesthetics.
MR4 is the perfect illustration of comfort = performance mantra we are proud to defend since the very beginning of 2-11Cycles.

Either you call it All-road, road or gravel bike the MR4 will take you anywhere for a lifetime.
