    Will 25.4 to 31.8 stem shim safely clamp 26?

    Just wondering?
    There's something about those long grueling climbs that gets my front end all stiff... And I'm not talking about lockout...

    I ran 25.4 deity bars with a shim in a thompson 31.8 stem for a year before I got 31.8 bars. zero issues.

    Yea but will the 25.4 shim safely clamp 26mm bars? There are 25.4 bars and 26 bars. I'm talking about road drops.

    No clue, the shim was extremely tight on my set up, you might risk damaging your bars?

    the answer is no. Mixing and matching 25.4 and 26.0 bars and stems always leads to a problematic install. Since you want to put big bars in a small stem your going slightly crush the bars. 26.0 stems aren't that expensive, just get what you need to make the setup work properly.
