The New Mosaic RS-1

August 8, 2019

Mosaic Cycles is pleased to announce the new RS-1: a steel road bike that blends cycling’s oldest frame material with 21st-century tubing technology to create a thoroughly modern road bike with the classic look and signature ride feel of high-performance steel tubing.

 

Even in this modern age of F1-inspired carbon and aerospace titanium tech, many riders still whisper of the ride of steel in reverent tones. This devotion to the uniquely lively ride of a handmade steel frame is the reason Mosaic developed the new RS-1 series.

 

“Having a really solid steel road bike in our line-up really completes the models we offer,” said Aaron Barcheck, Mosaic Cycles founder and lead framebuilder. “We’ve brought our own Mosaic perspective to the steel road bike; all the things you’d want out of a modern bike with the timeless ride qualities of a premium steel frameset.”

 

Available in both classic rim-brake and modern disc-brake configurations, both variants share the same Columbus Spirit HSS tubing with an elegant tapered head tube and reliable threaded bottom bracket. Classic road bike aficionados will appreciate the details like “star” cable port/bottle boss reinforcements, braze-on front derailleur mount and integrated derailleur hanger.

 

The RS-1 and RS-1d will be delivered six weeks from the order date, a lead time unmatched in the handbuilt bike world. Remarkably, Mosaic’s dedication to efficiency and tight process control allow them to deliver any bike from their catalog in six weeks. This combination of performance and beauty; delivered in record time, is what Mosaic calls “The New American Handmade.”
