Super-Clean Minimalist Road Build

Like things clean, simple and nimble? Check out this minimalist road bike build to inspire your own custom CIRCA.
Weighing in at a lean 19 lbs, this fast and light road build is a perfect solution for everyday, all-weather riding.

The Frame

The frame is constructed of bonded, anodized 6000-series aluminum, with lugs that were cut in Vancouver, WA, using our proprietary modular construction system. For the rider, the geometry is super-versatile and could be considered ‘recreational’ for it’s slightly laid-back angles and longer chainstays. It would be a great commuter, daily rider, event bike, winter beast, or distance bike. Drawing on our Portland, Oregon heritage, there’s ample clearance for fenders, and the frame is designed for long-reach brakes to simplify fender mounting and allow wider tires. For this frame, we took advantage of local laser-engravers to apply all of the frame graphics. The combination of lasers and anodized aluminum creates a graphic that’s virtually indestructible.

Color and Finish

For the color scheme, we went with a very minimalist “Space Gray” anodizing for the majority of the frame, accented with red color hits at the head-spacer and rear brake bridge. The tubes and lugs are all hand-textured before anodizing to create interplays of light.


We started with Shimano Ultegra as the foundation for the drivetrain. It’s a great balance of value and performance.

Stem and Seatpost

I love U.S. made Thompson components for their performance, heritage, and commonality to Circa’s frames, in that they’re CNC’d using similar techniques to our lugs.


We went with silver long-reach Velo Orange rim brakes. These are by far the most beautiful long-reach brakes on the market, and the final surfacing is done using CNC equipment, so there’s a common aesthetic to our frames.


American-made Velocity rims, mated to red hubs from Portland’s Chris King and hand-built by one of the best (and least known) builders in Portland: Tom Patterson.
