Handlebars: 25.4mm or smaller clamp

Handlebars for older style quill stems come with different centre sleeve diameters – this should be matched to the clamp diameter of the stem. Common centre sleeve diameters are 26.4mm (most Cinelli pre-1995), 26.0mm (3TTT, Mavic, some ITM, some Nitto) and 25.4mm (SR, GB, some Nitto and ITM)

Please note that older aluminium bars should be checked carefully and frequently for cracks especially if there is scoring on or near the clamp area.

For other sizes of handlebars:

26.4mm Clamp ∅

25.4mm and smaller Clamp ∅
