Why It Matters
Unveiled at the 2025 MADE show in Portland, Oregon, the RT-Zero is the first release from Mosaic’s Zero Ops division: a titanium road frame built around CNC-machined parts made in-house. We ordered this one for the shop, a standard 56cm painted in Mosaic’s Artist Series Shatter layout in white, and it’s ready to build.

More about the RT-Zero
The RT-Zero introduces a series of precision CNC-machined titanium components, including a one-piece UDH dropout, bottom bracket plug, seatmast and seatstay collar, designed and made in-house. These parts carry a D-shaped carbon seatmast and topper. The frame also has a tapered head tube and a T47 bottom bracket, with full internal routing.
It comes with an ENVE In-Route Road fork, a Chris King Aeroset headset, the Zero Ops seatmast and carbon topper, and an ENVE SES AR one-piece bar and stem, 120 mm long and 42 cm wide. It’s routed for Di2, with flat-mount disc brakes and Mosaic’s 12 x 142 UDH dropout.
It’s Mosaic’s standard 56cm geometry: 579 mm stack, 393 mm reach, a 72.8° head angle, a 73.5° seat angle, 415 mm chainstays and a 1,004 mm wheelbase. If it fits, it’s a way onto an RT-Zero without the wait. Ask us about building it up.
