Mosaic Announces the RT-Zero Titanium Road bike, Its First Zero Ops Drop
The first output of the brand's new 'Zero Ops' division, the new RT-Zero promises an evolution of Mosaic's celebrated titanium craftsmanship, featuring subtractive CNC manufacturing and a new D-Shaped Carbon Mast and Topper.
Today at the MADE show in Portland, Oregon, Mosaic Cycles unveiled the RT-Zero road bike, its latest flagship titanium roadster. With only 25 first-edition models slated for production (of which we've reserved two for Regroup), racy looks and a new level of refinement courtesy of the Colorado brand's intriguingly named 'Zero Ops' division, there's a lot to unpack.
The RT-Zero is the first frameset to emerge from Mosaic’s new Zero Ops division, a mindset and space dedicated to pushing the boundaries of titanium innovation, design, fabrication, and integration.
As such, the RT-Zero feels as much a statement of intent as it is a frameset. The brand’s latest titanium road bike leads with in-house subtractive CNC manufacturing to produce a crisp, durable, and uniquely Mosaic evolution of its highly respected titanium workmanship and design language. And in truth, CNC feels so much more Mosaic, more old-meets-new school than anything they could have dreamed up with 3D printing, a method favored by many of its peers. The result is a platform that feels modern and deeply rooted in the builder’s ethos of precision and craft. Notable examples of Mosaic’s new CNC method include the RT-Zero’s neat UDH dropout, seatmast and seatstay collar. Other areas worthy of your attention include the striking D-shaped carbon mast, which complements the new topper to round out a rash of updates.
Only 25 First Edition framesets will be produced, with two already reserved for Regroup (contact us to start a Regroup Custom build and make one yours). Each one comes as a module — fork, cockpit, Chris King Aeroset, and that striking carbon mast system included — at a starting price of $11,000, with a complete build starting from $15,000-ish. Options like Partington wheels and CeramicSpeed upgrades sweeten the deal, while finishwork spans from subtle titanium-and-carbon contrasts to a bolder Shatter Camo Artist Series that drops a day later.
When we spoke to Mosaic’s Brand Marketing & Sales Manager, Mark Currie, before the release, he told us that, “Underneath it all, the RT-Zero is less about chasing a trend and more about laying groundwork.” Adding, “We’ve coined the term ‘Mosaic Zero Ops’, which leaves room for further Zero Ops projects down the road.”
Mosaic calls Zero Ops its highest level of innovation and R&D, and you get the sense this project is a doorway rather than a destination. Today, it’s the RT-Zero. Tomorrow? The road is open.
