Stock or custom geometry options

Nine stock sizes run from 48cm up to 62cm in 2cm increments. The stock frames will be built in small batches, according to Mosaic. 

"We're excited to offer the RT-2 in a small batch stock configuration as it allows us to lowers the barrier to entry to a high quality, handbuilt in the USA titanium bicycle," said Aaron Barcheck, founder of Mosaic Cycles. 

If your measurements fall outside of a stock size, or you simply want a truly custom frame, Mosaic offers a fully custom option as well. 

Frame or complete bike available

Like most custom bike builders, Mosaic offers customers a wide choice of components.

For those who want a complete bike ready to roll, the RT-2 builds consist of Shimano Ultegra 8000 components with Mavic Ksyrium Elite wheels with 25mm Mavic tires. A carbon Enve Road 2.0 fork leads the way. Fizik composes the finishing kit of bar, tape, stem, seatpost and saddle. 

"We've worked with a handful of our retail partners to dial in the geometry and parts specifications to be in line with their current product line-up and offer an alternative to a mass-market production bicycle," Barcheck noted.
