Viathon R.1 Shimano


This bike is among the world’s lightest, even with a full complement of modern features including disc brakes and internal cables routings. Less weight means getting there quicker, after all. With custom-tuned carbon and geometry, every R.1 feels equally solid and responsive, no matter what your size or riding style. And thanks to a generation of building experience and relationships in the carbon manufacturing industry, we’ve done it all at a fraction of our competitor’s cost.


You don’t have to spend a fortune to go fast. The R.1 105 pairs a top-notch Shimano 105 drivetrain and hydraulic disc brakes to the same frame as our high-end build for unparalleled performance and value. And with a Zipp cockpit, Knight wheels, Continental tires, Fizik saddle and bartape, it’s the bike you’ve always dreamt of and now it’s within reach.
