Duralumin

Duralumin was developed by the German metallurgist Alfred Wilm at Dürener Metallwerke AG. In 1903, Wilm discovered that after quenching, an aluminium alloy containing 4% copper would slowly harden when left at room temperature for several days. Further improvements led to the introduction of duralumin in 1909.[1] The name is obsolete today, and mainly used in popular science to describe the Al-Cu alloy system, or ’2000′ series, as designated by the International Alloy Designation System (IADS) originally created in 1970 by the Aluminum Association.

Victoire Cycles | Roger’s Victoire Versus

Check out Victoire Cycles latest video about a Versus gravel bike they made for an Australian client.

For our first video, we wanted to highlight the client experience. The bikes we present in Our Creations section show it, a Victoire bike is the result of a common thinking with the client, combining his experience as a cyclist with our technical skills. Discussing the project, taking measurement, selecting the tubing, designing the geometry and at last building the bike are many steps that require great attention. – Victoire Cycles

Philly Bike Expo: Stanridge Speed Road

When modern builders utilize NOS tubing from the late 80’s, the results are more often than not, mind-blowing. Take this Stanridge Speed road bike from this year’s Philly Bike Expo. As soon as I saw it, I knew Adam had selected Gilco tubing (or is it?), yet there’s much more to the story, of which I’ll let Adam do the talking.

Adam, can you tell me about the Philly Bike Expo road bike? I’m suspecting there’s more than meets the eye here…

“I built the bike in conjunction with 7th and Park in Brownsville. It’s part of a larger project consisting of six available tubesets we’re making into frames. Three track and Three road. All the sets are NOS from the tail end of the golden era of steel in 1986. Most of the tubes are date coded. Columbus etched the iconic Dove and born on dates in the tubes in an effort to reduce false advertising by unscrupulous builders during this era. The story goes, builders in the 1980’s masked the imprinted doves on the tubing only to reveal the mark after the painting process.

One half of the Fabrica framebuilding team in Milano is a self-admitted nerd when it comes to NOS componentry including tubing. He scored the motherload of these NOS tubes a few years back. I met the guys at Fabrica through the RHC 5 years ago.. which ultimately led to the remaining tubing cache on the shelf within arms reach. What you see with the Columbus SLX tubing modified by Silva was an attempt to increase rigidity by adding surface area while remaining braze-able into a lug.

It was nice to work with the team at FSA to build a frame around their wireless WE group. Visually revisiting the smaller diameters feels refreshing in contrast to the current double oversize shaped modern steel offerings. It’s the Juxtaposition. These tubes remind me of how steel has constantly been Johnny Hustle over the years – the hardest worker – in this case – to stay competitive against aluminum in the eyes of a broad consumer base.

I like underdogs and I’ve never waivered from Steel.

How does this tubeset feel? Do you think it ever had the slightest idea these components would be hung from its bones… Ha. Too much time alone at the workbench I guess.”

Rusby Cycles

Jake Rusby is a framebuilding instructor at the Bicycle Academy and one that specializes in beautiful fillet brazed construction. In a way, through teaching students this artistry, he’s passing the torch of knowledge to the next generation of framebuilders and since the Bicycle Academy’s student reach is worldwide, his impact will only have positive results in the industry as a whole. This is Jake’s personal bike. It’s an all-day road frame, built with Dura Ace, with a more relaxed geometry when compared to a crit racing machine. Jake wanted a bike he could spend every waking moment on, soaking in the sun in the British countryside outside of Bristol, where he recently just relocated from in London.

What is most impressive about all of this is that Jake painted this bike himself. He wanted the contrast of a single color, with areas of intensity in the details. After masking off dozens of dots, he began the painting process, resulting in a halftone-inspired final product which achieves his intention quite well. Other details I found intriguing are the split seat stay bridge and head badge, both acting as a reflection of the other.

Donhou Bicycles



We were honoured to have our speed bike on display at the Design Museum in London as part of their Cycle Revolution exhibition earlier this year. As part of the show the Design Museum commissioned a short film, explaining a little bit about how Donhou Bicycles came to be – as well as what possessed us to try and make a bike that could go 100 miles per hour on the flat. If you missed the exhibit itself, be sure to give the video a watch.

A little question and answer with Tom Donhou!

So you started in 2010?

Yep I think so, can’t totally remember but sounds about right! We went fully public at the first Bespoked show…

That years bespoked (the first) in Bristol was really the first time for me that I saw bikes like yours. Your Pimento Stuffed and Rickys Track build from that show are still very memorable, you both stood out quite clearly at that show, at the time there were not so many new builders…I guess you wouldn’t have imagined there would be so many now?

Yeah we took Best in Show with the ‘Pimento Stuffed’ bike that year. Going there was a total unknown, as the resurgence in frame building in the UK hadn’t really happened. That show was essentially the start of it, so it was an interesting clean slate and great to have been there…
