25.4mm clamp diameter (look below!)
26.0mm clamp diameter
26.4mm clamp diameter

Quill stems come with different clamp diameters and occasionally different quill diameters.

Common clamp 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)

I personally think you can use Cinelli stems with 26.0mm clamp bars but the official recommendation is that 26.4mm stems should be used with 26.4mm bars and 26.0mm stems should be used with 26.0mm bars.

We measure stems centre to centre across the top – this does not always correspond with the manufascturer's markings.
