Mosaic RT-1

Bikes starting at $8500

The RT-1 represents the top of the range for Mosaic road frames. It features custom butted 3/2.5 tubing in a wide range of diameters to match the ride you are looking for. Custom geometry is a standard feature and included in the price. Also included is an Enve 2.0 1.25 tapered fork and the King i8 headset. The RT-1 comes standard with a 44mm head tube, choice of bottom bracket shell, standard 30.9mm seat post diameter or integrated seat post (ISP). There are also a few finishes (not including paint) that are available as well, though the brushed finish is our favorite.

Additional options include internal brake cable routing through the top tube, internal shift cable routing, disc brake set up, Shimano Di2 or Campagnolo EPS internal routing, custom paint and S&S couplers.

Since everything with the Mosaic RT-1 is custom we can build it to match the way you like to ride, from extremely oversized and super stiff for the sprinter, to a mix of diameters and specialized butting to build an exceptionally light and smooth frame for the lighter climber to anything in between.

At Above Category, we excel at taking your input and communicating that to the builder to produce a frame that rides as promised. Mosaic makes this an easy proposition by offering so many options with the RT-1.
