• As this post is based around performance I would think you need to ride a high performance modern bike and an older style steel thing (even with quill) back to back to see how noticeable it is for you at your performance level and if it is noticeable whether it actually matters/is worth bothering about.
    If you are are not racing on it then what is a few seconds over an hour. Can't imagine that would be noticed without a stopwatch.

    You may well have done that so ignore me but thought it was worth pointing out.
