3TTT Quill Stem 22.2-26-105 mm Vintage Road Racing Bike Eroica PO24

This 3TTT quill stem carries the measurements that decide whether a classic cockpit comes together: 105 mm of reach, a 22.2 mm quill and a 26 mm clamp. For anyone rebuilding a machine to Eroica rules, the numbers matter more than the badge.

What the dimensions tell you

Reach is the figure that shapes how the bike feels under you. At 105 mm, this stem sits in the middle ground:. The 22.2 mm quill is the diameter that fits a standard threaded steerer, and the 26 mm clamp matches bars of that same nominal size. There is no room for improvisation here — either the bar and the steerer measure up, or they do not.

Construction and origin

The stem is made of, and it carries a declared country of origin of Italy — consistent with 3TTT, a marque long associated with Italian component manufacturing.; on this used stem

Matching the rest of the cockpit

A stem is only half of a cockpit, and the bar has to agree on clamp diameter. If you are still hunting for a handlebar to complete the build, our Randonneur racing handlebar, 385-25 mm is listed in the same radius of the catalogue, and the 390-24.4 mm Eroica handlebar is another option worth measuring against your own frame. For a wider sweep of period-correct steering parts, the wheels and components section is where the rest of the front end sits.

Condition notes

This is a used part. The photographs supplied with the listing form part of the description and show the stem as it stands; we have kept the wording strictly to what is declared, which is that the item is second-hand.
