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. A particular blend of oversized internally double butted and thin walled straight gauge tubes make a responsive handling characteristic without losing the quality ride steel frames are known for and keeping the weight as low as possible. As our flagship road model the RS-1 is delivered in any configuration of road components and spec: caliper, disc, etap, di2 and more. Complimented by full custom geometry and paint by Spectrum Paint and Powderworks will truly be unique to each rider.
The RS-1 is the steel bike for the carbon aficionado, for the racer looking to stand out from the crowd, and for the rider looking for the classic ride of steel in a mass palatable to even the biggest of gram-counters. We’re happy to report that we’re all three at different times, and the RS-1 remains one of our favorite bikes. The RS-1 meets the same level of methodical quality and attention to detail that Mosaic is famous for as a standout American builder, with a litany of paint options, finishes, and add-ons available like fender mounts, disc mounts, pump pegs, and brazed-on seatclamps.
