Scene from a misty morning heading south out of Portland. Thanks to @mroui for the pic and the fine company.

Great morning for some mixed terrain in Portland.

Great morning for some mixed terrain in Portland. Had to stretch a tight calve, so I figured I’d make the best of the time off the AllRoad and snap a pic or two. There’s a hilariously large stick (branch) holding up the bike on the other side that somehow managed to be somewhat hidden.

Say hello to our bottom bracket, affectionately kn

Say hello to our bottom bracket, affectionately known as BB-5AX. That’s not a rendering. It’s the real thing, hogged out of a solid block of aluminum billet. It’s a serious exercise in form, function, precision and strength and it forms the foundation of every CIRCA frame. And it’s So F@cking Metal (SFM™).

On the form side, every surface, edge and line has been considered to harmonize with the rest of the frame’s visual language. Those little chamfers? They show up throughout the composition to knit everything together. The angled bores for the tubes all align with other aspects of the frame to create a coherent visual statement.

With respect to function, we’ll start with the milled threads for an English BB. No creaks and no presses required. For those of us who ride in foul weather, there’s also an integrated fender mount.

On the precision end, these are milled on 5 axis CNC machines (hence the name) to extremely high tolerances of 5 thousandths (0.005”) of an inch in some areas and a little tighter in others. Those tolerances serve a few purposes. The first requirement is bond-gap management. We’ve got very specific targets and this gets us there. The second benefit of that precision is the obvious one about your frame being straighter and truer than almost any other hand-built bike.

And it’s stout. Rigid. Efficient. Milled from a solid block of aluminum billet, the BB-5AX is designed for power transfer. You put force into the pedals and the force gets translated into forward motion.

Our house doesn’t have a garage, so the entry hall has functioned as the landing spot for my daily rider (much to the chagrin of my wife). Over time, the wall got marked, scuffed and beat up, so we’d been thinking about how to improve the situation. I finally knocked out a solution earlier this week, installing molding, doing some darker, scuff-hiding painting that tied in with other parts of the house and adding a custom acrylic plate with some nice fasteners. Whadayathink?

AllRoad 3.0 August Special Promo Build We don’t

AllRoad 3.0 August Special Promo Build

We don’t typically sell pre-built bikes, but we’re offering special pricing on this CIRCA AllRoad 3.0. It’s got the versatility and utility to handle open roads, twisty climbs, remote stretches of gravel and long miles. On the practical end, external hose routing means you can actually work on your bike and there’s fender mounts if you’re like us and ride in foul weather. Heads up that there’s a little blemish on the seat lug, but that’s part of the deal for this one. As always, the frame is hand-built in Portland, Oregon from tuned, bonded, anodized aluminum tubing and precision-CNC’d lugs using our proprietary build system.

Build Overview:
Size: L (56cm, geometry details on site)
Frame Construction: Bonded Aluminum
Group: Sram Force AXS (D1, 2x12)
Wheels: HED Belgium rims and DT Swiss 350 hubs
Colorway: Grey + Pewter (anodized)

Special Pricing for this one-off build (with small blemish): $4,995 + Free Shipping in the US.

Message us for more info or visit our site and submit a contact form if you’re interested or have questions.

Feeling a little under the weather today, (ironic, since it’s finally sunny here in Portland) so I’m down in the shop trying some new ideas on the laser. This pattern feels like rain to me, so maybe it would work as a detail on someone’s rain bike? Full circle: sunny day, rain day, rainy graphic!

The rains came back with a vengeance today, so it’s a great time to try some new ideas with the laser. Since the etched marks will always be rendered in white on anodized tubes, here’s a quick study on a photographic image that relies solely on highlights.

We get a lot of comments about our seat lug cluste

We get a lot of comments about our seat lug cluster, so it’s time for a deep dive. As with many of the other elements on Portland-built CIRCA frames, there’s a bit of thought that went into balancing form, function, precision and strength.

On the form side, every surface, edge and line has been considered to harmonize with the rest of the frame’s visual language. Those little chamfers soften sharp edges while leveraging our super-thin anodized finishes to catch the light and bring a subtle crispness. They show up throughout the frame to knit everything together. The angled bores for the tubes all align with other aspects of the frame to create a coherent visual statement.

The fasteners that connect the seat stays to the seat lug are engineered to reduce the number of CNC’d parts, because all that CNC work gets expensive. After studying stress points throughout the frame, it was deemed that that area was a smart place to find efficiencies without sacrificing strength or performance. Once assembled, this area is rigid and doesn’t move. In the unfortunate (and unlikely) event that your seat stays would need to be replaced, they can also just be unbolted and a new set put in place.

There’s an integrated seat post clamp to keep things simple and clean. That’s a 31.6mm round seat post. It’s easy, it’s common and there are tons of aftermarket options if you want to customize your post experience with suspensions, droppers, etc. That little fastener on the side is an M5 threaded accessory mount.

On the precision end, like all of our frame connecting elements, these parts are milled on 4 and 5 axis CNC machines to extremely high tolerances of 5 thousandths (0.005”) of an inch or better. Those tolerances help ensure precise bond-gap management and let us create a frame that's straighter and truer than almost any other hand-built bike.

Finally, like everything on our frames, it’s stout. Milled from solid blocks of aluminum billet, the CIRCA seat lug cluster is designed for strength and durability.
