Stainless Steel Touring Bike

This bike has gotten a lot of attention so far in its short life. People seem to like shiny things, and this one does indeed shine. Beyond being blindingly bright, there are so many details that I figured I ought to lay it out for those who might be interested. The bike is mostly finished. There are a couple more bags that need to be made, and a decaleur that will mount off the stem -- in this sense it is still a work in progress. So, here's the low-down:Stainless Steel Touring

Spork Head Tube BadgeThe frame and fork are made from KVA stainless steel. The split-plate fork crown is made from laser cut stainless.  The racks and stem are made from chromoly steel, and were polished and chromed.

The bike has 26" wheels (international standard -- this is a touring bike, after all), disc brakes, a connectorless front generator hub made by Schmidt. That means that there is no plug to worry about when changing a flat tire. The wire runs from the inner face of the dropout directly into the fork leg. The front and rear lights are powered off the hub, and the wiring is all internal.Breakaway Binder

The frame is a breakaway style, with a coupler on the down tube, and a breakaway point on the seat tube. The seat post is integral to the structure of this system, which is brilliant and simple (No, I didn't invent this. Neither did Tom Ritchey -- it came from way further back than even his design). The seat stays come in below the seat tube breaking point, and the rear rack stays attach higher up on the seat tube, where seat stays would normally be. This gives the bike the appearance of having a traditional rear triangle, and serves to support the rear rack. 

Front Rack & LightThe front rack has an upper deck that can be used intependantly of the low riders, which are detachable. The rack supports the fender and the front light. The rear rack has an integrated u-lock holder. Notice the leather sleeve on the lock shackle. This was made by Dirt Jr., right here in Portland. I plan to put these up for sale on my website soon. They look so much nicer than what comes with the lock. We're working on a vegan option as well. 

Rear Rack & Lock HolderThe frame uses traditional tubing dimensions (1" top tube; 1 1/8" down & seat tubes), and has a straight truss, or second, top tube. This supports the head tube and seat tube, stabilizing the ride for weight bearing, particularly when the bike is fully loaded with bags. The space between the two top tubes was an ideal place to add storage, and the frame bag was custom made by Black Star Bags here in Portland. There's enough capacity in this bag to carry a couple of tubes, maybe even a folding tire, tire levers, patches, a multi-tool, energy bars, phone, etc. 

Stainless LogoThe down tube logo is also stainless steel, laser cut and brazed on. It took three of us to keep it set while brazing. Next time, I need to video record the process. I left the panel around the logo exactly as it looks right after brazing, without polish. That gives it the burnt, dirty look, which really stands out nicely.

There is a polished titanium spork head tube badge that is removable, and fully functional. People who ride bikes have to eat, right?Stainless Steel Touring

Part of the reason I built this bike was because I hadn't yet seen a really utilitarian bicycle made from stainless steel. Stainless is expensive, and the amount of time and labor required to bring it to a mirror finish was ridiculous, but the final product is so striking that I believe it was worth it. I hope you agree. I would like to see the same style bicycle, or something worthy of commuting, made from stainless steel and with a brushed finish. Everything Shiny!

Polished StemAnother reason I built this bike was because I was invited by the Portland Art Museum to display a couple of bicycles along with the Cyclepedia exhibit this past summer, 2013. It was an honor to be invited, and I wanted to make something that I believed was worthy of being shown in such a prestigeous museum.

Here above is the photo series from my flickr site. There are a few repeats, but I chose to use them all, because each of them looks so good. Photo credit goes to Anthony Bareno. He took all these in the studio at Velo Cult. He said it was the most difficult bike he's ever shot. Too many reflections. If only there were some way to photograph this bike in the dark! Please check back in the future to get a full ride report.

Aurelio Commuter

Aurelio CommuterThis is a bike that shipped to Aurelio just before the holidays. This one took a lot of hours, and a lot of weeks to complete. At base, it's a commuter bike, ready to do all the daily chores of getting around to work and to the store. But, it's a whole lot more than that besides. Take a look at the photos, and you'll see that it's all in the details.

Emre Stainless Steel Road Bike

Stainless Steel BicycleEmre's bike is a full stainless steel lugged road bike. The geometry is more upright and relaxed than a racing bike, meant to be comfortable on longer rides. The frame design is pretty straight-forward. There is clearance for 28c tires and fenders, and the bike has a very minimal rear rack. Custom panniers are currently in the works from Philosophy Bags in Camas, Washington. 

Shiny Head Lug

One noteable thing about the bike is that I used the Pacenti Artisan lugset, which is now a piece of history. I'd had these lugs sitting around for a couple of years, and they are no longer being made. 

Shiny Seat LugI don't have much more to say about the bike. Understatement of the year is that there was a lot to polish. The finished product is pretty amazing. I think the photos speak way more than words can. I've included quite a few photos of the build process as well. Particularly of the steps involved in the down tube logo. The logo is laser cut stainless steel, brazed on and polished, then masked and the panel was etched, then re-polished. Quite a few steps, and pretty interesting I think. All the photos of the finished bike are by Arthur Smid.

Michael A 650b Randonneur

 

Michael A 650b Randonneur

Here's a classy lugged 650b randonneur. It's got all the basic requirements -- comfortable geometry with a low trail and stable handling with or without weight in the front handlebar bag; it's got a front generator hub and bright front light wired through the rack; the bike has plenty of tire clearance for fatter tires, and long Honjo fenders with mud flaps to keep the road spray off. There's a light duty rear rack that can accommodate small panniers for those short bike camping trips. The drive train is Campagnolo, and everything works like a dream. This is a bike that begs to go out for some seriously long rides, and is meant to be comfortable the whole way, no matter the road conditions. I'm envious of Michael, especially since this one is just about my size.

Enjoy!

Lee R. Stainless Road

This is one of the fanciest bicycles on the road. It's a long distance, fast climbing, polished stainless lugged road bicycle. Many hours of work were put into the finishing polish of the stainless, and the effect is amazing. The final powder coat is shadowed with Celtic knot work, and the lugs are finely outlined for highlighting. Lee has put a lot of miles on his bike, and the reports have been good. He loves to climb and likes the century rides, which is exactly what this was built for. And it certainly catches the eye! Beautiful, light and fast!
