May one suggest a DeAnima De Fer? I have ridden one, albeit briefly as it was slightly too small, and it was lovely. I now have one of their De Fer gravel bikes which I am in the middle of building up as a test rig. The quality of the welds and the finish are exceptional. I gave them a tough brief and they delivered.
Gianni Pegoretti is the man behind the welders torch. He knows what he is doing. He has been building steel bikes for years and can build you anything you want. The detail touches like the replaceable cable adjuster mount, the custom paint job and the internal routing for the rear disc are highlights.
They built a prototype carbon gravel bike for me to try which I then gave feedback on. After a lot of research, I settled upon a design which they were happy to build after giving it a thorough going over and feeding back their suggestions.
They build using custom Deddaciai tubing, are fully custom and disc specific, if you want it.
They are also really easy to deal with and very few can touch their experience and pedigree.
Oh and they used to build frames for the likes of Indurain although, of course, their bikes were rebranded to keep the sponsors happy.
Hope this helps?😀
