I love it. When I first started using the Columbus Zona tubes I just loved the feel of the material. I like all types of materials (prefer ones that are safe to touch) but going just one step further Skip and I built a frame out of The Columbus tubes with Niobium. I am a little confused on the branding that goes along with this particular set but the tubes came to me with very short butts but fairly gradual transitions.

This was one of those deals where the customer came in and rode for us a bit on a resistance stand and Mickey worked on his positioning.

I could see how the guy was making power. I had been thinking a lot about it while riding road over the past few years but mostly from my production of miles over the period of a whole ride. It was a good experience for me since I have also benefited from his advice on my green “undersize” bike (what I call it) so I am working on a proper device for adjusting positioning on the fly while measuring output in all my free time. It’s actually a priority after some other “OMG I better get that done” type of jobs.

What I do actually get done is way more than it looks like in your are reading this mess. I am pretty sure I covered the mitering machine but I also made the bike I brought up before spinning off topic.

I shaped it to decrease it’s frontal real estate without making it whippy. The fella is pretty narrow but is expecting forwardness when he addresses the pedals so it will deliver here. The seat tube is really big and will have big dirty tire hiding behind it so I left it alone. I left the seat stays alone because kids want roomy chain stays and someone has to pay for it. I squared the front of the chain stays and used a fat bridge because I couldn’t stop myself at that point.

I usually don’t really look forward to welding the freaky thin tubes. These were pleasure after mitering with the belt sander mitering machine. I was able to weld the while bike in a single pass, full manual. I had to wash only a tiny bit. Usually thin tubes are welded at least twice because they are just really difficult to weld.

I will have it cleaned up later today and will update with more pics.
