    Stem under crown on a Lefty?

    I know it sounds stupid, but with an XL lefty, I could fit the stem under the top crown and preserve the original height. The measurements work for my frame, headset, and stem.

    Could this work? I am not going to go out and do it any time soon, but I am curious if there is any reason why I couldn't.

    Thanks

    I should give some more detail here. I am running a Lefty Max on my Dos Niner with a 100mm head tube, and want to put a Lefty Speed on it to lower the front end. With a Cane Creek HS, Short Stem height, and XL Lefty, the measurements work to fit the stem beneath the top crown.

    I know this isn't standard, but is it possible? A standard lefty makes me run about 20mm of spacers between the headset and the top crown, and I am really looking at lowering my front end. If not, I can just get a steeper stem, but if this works I think it might look unique, even more so than the standard lefty is already.

    No reason why not!

    Uhmmm, interesting! It should work fine. I mean if the stem is positioned relative to the top of the head tube as it would be with a standard fork tube, then the geometry isn't really different.

    The issue I would think about is how the steering felt. I have noted subtle differences with where my bars are relative to the stem. I run a negative rise stem with 1/2" riser bars and it does feel a little different from a flat bar on a flat stem. It may have to do with leverage.

    So that being said, with the stem below the top clamp (Additional mass above the steerer), it may feel a little different then having the stem above the entire mass of the fork.

    I'd say try it and let us know how it goes....

    And by all means, post pictures!!!!
