Engineered for precision and speed, the RT-1c showcases the timeless appeal of titanium with caliper brakes.

We love disc brakes. But as a bike manufacturer we’re all about giving the riders what they want, and some riders still want rim brakes. We get it, and we're happy to make it happen.

We get it. The RT-1c offers a sublime road feel, exceptional handling and durability Mosaic is known for along with the simplicity, elegance and weight savings of rim brakes. And thanks to advancements in road calipers and carbon forks, the RT-1c can take advantage of the plush ride, added grip and lower rolling resistance of 700x28c tires.

LIke all Mosaic 1-Series bikes, the RT-1c is custom sized and precision crafted using a rider-matched blend of our lightweight butted titanium tubeset and available with a variety of drivetrain and finish options.

Taking into account each rider’s aspirations and use case for the bike, we continue to fine-tune the design to culminate in a riding experience and handling that is perfect for each unique frame that we build.
