Mosaic RT-1 Custom Road Bike

One of our favorites at NAHBS (North American Handmade Bicycle Show) every year, Mosaic Cycles shows off it’s exquisite titanium incarnation called the RT-1.
Handcrafted in Boulder, Colorado by Aaron Barcheck using 3/2.5 titanium, RT-1 represents Mosaic’s top-of-the-line Ti frame. Indeed, as a custom frame, the customer pretty much can go a la carte in terms of features – such as, internal brake and shift cable routing, EPS internal routing, disc brake mounts, seat mast or seat post, even S&S Couplings, along with a myriad of custom paint options. 

Absolute elegance and simplicity in an age of "hard lines" and nonsense "aero hooha" !  

The Gabor sisters could only dream of having stretch marks that looked as good as these welds !

Checkout those deep sculpted drop-outs ! 


The RT-1 presents the best of what Mosaic has to offer with it’s Road lineup.  Performance add-ons blended with a lightweight Double butted titanium tubeset make a bike equipped for anything.
