Even in this carbon and titanium age, many riders still prefer steel. This devotion is the reason Mosaic developed the RS-1 series. 

“Having a really solid steel road bike in our lineup 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 rim-brake and disc-brake configurations, both variants share the same Columbus Spirit HSS tubing with a tapered head tube and threaded bottom bracket. Also featured are classic road bike details like “star” cable port/bottle boss reinforcements, braze-on front derailleur mount and integrated derailleur hanger.

Like all of its other models, the RS-1 and RS-1d ($5,600) will be delivered six weeks from the order date.

RS-1 Highlights

  • Rider-specific custom geometry and tube set.
  • Chris King Dropset Headset.
  • Threaded 68mm bottom bracket.
  • 27.2mm seatpost.
  • Mechanical/Di2/EPS/Etap shifting available.
  • Choice of Mosaic paint layouts and 45 stock colors.
