Bike of the Week: A Purple to Green Mosaic All-Roader

This week we share our latest creation in partnership with our Boulder based frame builders. A fast, capable, and beautiful Mosaic GT-1—a custom built titanium gravel bike, with a custom tailored build spec, optimally suited for equal time spent on the road as in the dirt.

The purple to green ombré finish is stunningly executed on this bike. While the paint takes the spotlight, let's not forget the beauty in the titanium frame that lies beneath. Custom designed to meet the rider's smaller stature with perfectly tuned geometry and hand selected tubing. As this was more of all-road build we went with the Enve... you guessed it, all-road fork to keep things a little lighter and tighter.

The drivetrain is full Shimano, but a unique mix across lines. We used GRX for the levers and brakes, taking advantage of their extra security on the hoods and for the Servo-Wave braking performance. There's also a GRX Di2 rear derailleur and 11-34t cassette. Unfortunately, there's not yet a 165mm crank in the GRX, nor is there a powermeter option. So for that, we went Dura-Ace with compact rings, and matched it with an Ultegra front derailleur.

For wheels, we selected a set of Enve G23s for their lightweight, wide inner width, and rugged durability. They're laced to a set of Chris King R45 hubs. Again, as an all-roader, a high volume slick tire was in order. In this case, a Panaracer  Gravel King slick in 32. The green valve nuts on the Orange Seals valves are the perfect finishing touch.

Finishing out the build is an Enve carbon cockpit. Bars wrapped in Fizik 3mm tape and the seatpost topped with the new Cadex carbon saddle.

Yet another example of custom titanium done just right. This one is heading back out to Boulder, CO for a life soaking up the front range climbs and farm roads.

And don't be surprised if this bike looks a little familiar... It shares a striking resemblance to Derek's GT1 we built earlier this year.
