The RT-Zero is the flagship model in Mosaics’ Zero Ops range. Zero Ops stands for the in-house engineered carbon seatmast and topper. This D‑shaped Zero Ops mast uses an aerodynamically optimized profile that not only reduces drag but creates a stiffer structure as well. In ways that a round tube cannot.

The combination of carbon and titanium tubes gives the bike a distinctive and sophisticated look. On the road, the oversized downtube and Zero Ops carbon seatmast create an exceptionally stiff bottom bracket and ensure an instant acceleration. It is fast on steep climbs and offers confidence on fast descends.

Additional refinements include a tapered IS52/52 head tube, flat‑mount UDH dropouts, a T47 bottom bracket shell, and full‑length internal routing. A compression‑molded carbon topper with premium ENVE hardware completes the D‑shaped seatmast.

“The RT-Zero is the first model by Mosaic Zero Ops, the result of over 15 years of titanium frame fabrication combined with countless hours of in-house dreaming, development and testing of these enhancements in the pursuit of the ultimate Mosaic…so far.”

The RT-Zero can be pre-ordered only at selected times in the year, so if you are interested in this stylish and high-quality ride, check out the contact details on the Mosaic website.
