getting close atmo -
The cross season just ended in FL. No more dirty cross bikes till October.
Back from paint - track bike for myself. To be ridden on a track.
and another...both arrived back today from the painter. This is a bike for my brother in law.
From freezer to asphalt...grass, dirt or whatever.
Wanted to keep these very simple and minimal.

No shifter bosses?... What's that little rubber thing for?

See ya at the show!
Embrocation coverage of the new Spooky shop in Medford. Ricky (aka RFD) here is the comrade spearheading that place, along with a bunch of young engineers and crusty old Merlin and Fat employees.
Bikes arrived in Berkely this week for ClifBar.
The first NAHBS bike arrived from paint this week. Still a lot left to take care of...
The seventh Design and Form by Llewellyn, the fifth lug set.
The “Cadenzia” lug set is a joint design project between the Italian frame building legend Dario Pegoretti and Darrell Llewellyn McCulloch.
These are the world’s first and only lugs for XL tube sizes with a level tube.
These lugs sit along side the XL Compact set, so the builder can have a level or sloping top tube design utilising XL (double over size) tubes in their design offerings.
Larger diameter tubing is required for the tall/big lads to ensure the bike has the correct handling properties.
The inspiration behind the Cadenzia name came from the word ‘Cadenza’ which is an impassioned improvisation played by a virtuoso soloist toward the end of a musical performance. In Italian in means Cadence and rhythm. A quite fitting name for this lug set.
This lug set is an exciting project and a story about how this kicked off may be of interest.
In 2009 I did a mechanics stint with the Under 23 Australian National team in Italy finishing up with the World Championships where Jack Bobridge won the U23 time trial.
MaryAnn and I had arranged a holiday afterwards in Italy and were invited to visit my fellow Frame Builders’ Collective colleague Dario Pegoretti.
Not long after we arrive at Dario’s Caldonazza workshop he sits me down and a very nice bottle of Italian red wine is opened. Not unusual for me to partake in some red wine, however this was 10.30 am!
Dario puts to me his desire for an XL tubed lug set and he knew of my intention to produce a new lug set. However the design project I was working on was the Custodian OS tube lug set, not an XL size set. That was sorted out, then ideas and design details were sketched out. The end result after the wine, good food and Dario’s passion for the frame metal work now over come me and now I was working on two lug designs at the same time when I returned home.
Dario also started work with Columbus to produce a new stainless steel tube set that if desired can also be used with these lugs.
The “Cadenzia XCr” stainless steel tube set.
It was after many days in front of the Computer as I worked the 3D CAD program to do the models.
The lugs have the Italian style to them. However one can modify these lugs to have the curvy shore lines similar to what I desire. Just the right amount of room for elaboration or use as they are. I like the ability to shape to one’s own style and tastes.
This lug set has all the usual desired features such as a stainless steel M6 cap head seat binder bolt, anti seat post damage shape to the key hole slot, cast M5 gear bosses with spring counter bore on the DT lug, lots of seat tube skirt to allow the builder to trim to fit around the desired seat stay attachment style and also fit large diameter seat stays with large frames. 36 mm head tube for 28.6 steerer forks
Lots of stack height on the top head lug that can be trimmed to suit the frame design.
For the stainless polished lugs there is a shelf in top of the seat lug that sits on top of the seat tube. This avoids the exposed braze line between seat lug and seat tube and also removing the need to make a small piece of stainless tube to sit on top of and inside the seat lug to avoid the otherwise exposed rusty top edge of the seat tube.
All the effort was to ensure that no detail in the design is left out.

Back up and running made this with that, or that with this.

Breakfast at Tiffany's?
Nah, Friday breakfast at Anvil and that's Matt, aka "Elroy", not Audrey Hepburn.
You guys were expecting the Super Journeyman, weren't you?
Mmm... bacon... oh what? Here's some pictures.
stainless fork-ends; BIG surface area for silver-solder = peace of mind.......(the plug is brazed-in)
