Specifically this seller:

They're selling Thomson stems, the one with 26.0 handlebar clamps. (EG: 0deg/70mm/26.0clamp
or 5deg/120mm/26.0clamp

The only thing is some of the ones that are listed don't match up to the specs listed on the Thomson site here:

They claim that they have new old stock but I don't trust it as I haven't been able to find other places selling those stems. Can anyone help me on this? I also have a feeling that all their listings are for 25.4 handlebar diameter.
