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 R1 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.
The R.1 Ultegra is the ultimate intersection of price and performance. You get the same frame as our top-shelf model, with reliable Shimano Ultegra shifting and hydraulic disc brakes. Zipp Service Course SL cockpit and lightweight Knight carbon wheels add pro-level performance. Money can hardly buy a faster, more refined bike.
