Passoni sources the best materials in carbon, steel, or titanium in the sector.
We use only grade 9 (3Al / 2,5V) and grade 5 (6Al / 4V) titanium – meeting ASTM aerospace industrial standards. Our industry-leading carbo-titanium and carbon fibre is sourced from Veneto, while we use Columbus XCR stainless steel tubing in our top tier steel bikes.
Passoni frames are all manufactured under close scrutiny in our atelier to maintain quality control at every juncture. Any contamination from oxygen, nitrogen or even traces of dirt can affect the quality of a titanium frame.
This is why, having sized and cut titanium tubes, our frames enter an arc-welding chamber to be welded in a vacuum filled with our own custom
selection of gases.
Steel and carbon frames made in our atelier enjoy the same level of care and attention, with Tig-welding and silver brazing in steel, and aerospace-grade autoclave curing for our carbon frames.
