All Mosaic frames are handcrafted from titanium in Boulder, Colorado, and the RT-1 is no exception. The quality of their welds is really something else. This RT-1 Disc brings a host of detail to that classical profile, with internal cable routing, flatmount disc brakes and thru-axles keeping things sleek and efficient.
This build in particular brings things bang up to date, with the latest SRAM RED eTap AXS 2x12 wireless electronic groupset minimising both the need for cables and the gaps between gears.
The US-made theme continues with a Chris King headset (and yes, they still make their own ball bearings in house) and a classic Thomson seat clamp. Not to forget those ENVE carbon rims, built onto Chris King hubs, and a full complement of ENVE contact points (plus their brilliant carbon cages).
In raw Ti finish this is an extremely cohesive, nicely understated build that's designed for long days and high performance.
