Road Gallery

Every Line, Edge and Surface has a Purpose.

Whether it’s the diamond-chamfer edge of our lugs or the subtle directional hand-grained textures we work into each component before frame assembly, each CIRCA frame is a deep story balancing form, function and process.

What our customers are saying

The bike is fantastic. So light yet rugged. I’m excited. Riding this bike on a beautiful fall day in Boston is pure joy.

Matt

The bike is absolutely beautiful!! The fit is excellent and I Iove the Gates system. Thanks for all your good work!!

John D.

I’d been riding ill-fitting, mass-produced bikes until my CIRCA. I knew a bike built for me would be an improvement, but I’ve been blown away at how much better it rides. The belt drive runs perfectly smooth. The design process was great and Rich was always quick to answer questions and help build the bike I needed. And it turns heads: I’ve been getting compliments since I first rode it away from CIRCA’s shop.

John C.

Just go in and let them make you the best and most beautiful piece of bicycling art you’ve ever owned. I love my CIRCA!

Kathryn

My bike is super great. I use it multiple times per week for my commute in Seattle and although my bike is designed and built as a “rough weather commuter” I even ride it occasionally for sunny weekend rides. The fit is comfortable and on the rougher roads around Seattle it handles the bumps and quick maneuvers easily.

PERSONAL SERVICE

It’s a little old school, but we believe in working directly with our customers to get to know your cycling needs.

DURABLE WEATHERPROOF FINISHES

Our sapphire-hard anodized finishes are lighter and tougher than paint and impervious to the harshest weather.

OREGON BUILT AND SOURCED

We’re deeply committed to local production. Our frames are built by hand to your specifications in Portland, Oregon using locally sourced materials and processes.

CUSTOMIZATION AND FIT

A bike should fit you perfectly. Your CIRCA will be tailored to your body type, riding needs, and aesthetics, right down to the laser graphics.

QUICK CUSTOM

Your custom bike can be built in as little as 8 weeks, which is a fraction of the time that most custom builders require.

LASER GRAPHICS

Our custom laser graphics options can inspire, tell a story or celebrate your brand. Work with our designers or provide your own artwork.

Geometry: Two Fit Options

Standard and Short-Reach

For sizing and to optimize the fit of your CIRCA, we offer 2 geometry types: Standard and Short-Reach. We think of it as Quick Custom. There’s no extra charge for either option.

 
Our Standard geometry works for about 90% of riders with typical proportions. The Short-Reach variation pulls in the cockpit a little to accommodate riders with shorter torsos or who may want a more upright position.

Standard Geometry

Best for riders with typical proportions who have no problems fitting stock geometries.

Short Reach Geometry

Riders who have long legs compared to their overall height (and a shorter torso) may prefer the fit of our Short Reach geometries. This fit can also suit riders who want a more upright position.
