A 3TTT Quill Stem That Matches the Numbers
The dimensions stamped on this stem are its whole argument: 110 mm of forward extension, 22.2 mm at the outside, 26 mm at the inside. No guessing, no spacers-in-lieu-of-spec. For a rider rebuilding an Italian-framed classic or a touring bike that still runs a threaded headset, those numbers either fit or they don't.
The stem body is aluminium, a material that has kept this part light enough to swing back into place after a coffee stop and rigid enough that it hasn't sagged into a different geometry over the decades.

Three Dimensions That Tell the Whole Story
110 mm of length positions the bars noticeably further out than the 80 and 90 mm stems common on smaller frames — a useful figure for riders whose cockpit has always felt cramped.

For the Eroica-Spec Build
Restoring a steel frame to Eroica condition means sourcing parts whose measurements actually match the bike rather than the nearest modern equivalent. This stem's 110 mm length and 22.2/26 mm diameters place it squarely in the classic road and touring cockpit conversation. Its aluminium construction keeps the front end responsive without adding grams that a vintage frame was never designed to carry.

Confirming the Fit Before You Turn a Wrench
Measure the fork steerer and the bar clamp independently. Because the manufacturer part number on record reads 0000 — a placeholder — rely on the three measurements quoted above, not on a catalogue code, to confirm compatibility.
