Mosaic RS-1
The Mosaic RS-1 is a performance bred piece of equipment that knows no limits, it is the pinnacle of what Mosaic has to offer in a steel bike. A particular blend of oversized butted tubes creates responsive handling without losing the quality ride steel frames are known for. As our flagship steel road model, the RS-1 is available in a variety of configurations of road components and spec: caliper, disc, etap, di2 and more. Complemented by full custom geometry and paint by Spectrum Paint & Powderworks, each bike will truly be as unique as the rider.
