Here is a Mosaic that we put together for a local rider. Mosaic includes custom geometry on all of their frames, and we used that ultimate control to shape the bike into one designed for long-distance comfort. It can fit up to 32mm width tires, and can accept front and rear luggage racks.
Aaron Barcheck at Mosaic does immaculate weld work on his frames. You can get as close as you like to the beads, and still you won’t see anything but smoothness. Notice how the bolts that hold the disc brake caliper to the frame thread into a small steel insert. This insert can easily be replaced if the threads get damaged … it’s not as easy to fix damaged threads in the frame itself!
This carbon fork with lowrider rack mounts was used because the owner plans on doing some multi-day riding with front and rear panniers. The touring-bike side of this Mosaic also led us towards using a traditional 32 spoke wheel with Mavic Open Pro rims. Those are Avid BB7-SL brakes doing the stopping duties.
This bike was built late in 2013, right after the Shimano Ultegra 11 speed 6800 group was introduced. It was right on time! Ultegra 6800 can accomodate a 32 tooth cassette that a bike like this would need. Excellent 3T cockpit parts complete the bike.
