  1. Here's my solution to having a super-small bike with a 5mm stem stack height
    and a headtube shorter than 100mm.

    Run out the cables early out from the bar tape soon after the curve rather
    than at the beginning of the clamp bulge. You guys probably already knew
    this (or wouldn't ever have to deal with a small bike) but I figured I'd
    share.

    Nope, I would just route the der housing in front of the bar, in front
    of the brake housing and then loop them into the headtube stops. Those
    are so short, I wonder if it affects the front end, like a sticky
    headset.

    It didn't cause any problems while riding handling-wise, but the problem
    came up when the front wheel would flop to the sides, splitting apart each
    ferrule from the extreme angle.

    Surprisingly, braking and shifting were never compromised due to keeping the
    housing lubed.

    Professional mechanics check casing length lock-to-lock before trimming
    them. Good habit to develop.

    Where there's uncertainty about stem height/length, 'longer's gooder' as
    you can trim easily later after a few rides.

    The length was fine originally. Over time, wheel flop caused enough stress
    to split. The area is covered in 90-120 degree derailleur housing bends
    with lengths of 4 in. or less. Exiting the bar tape early fixed the
    situation.
