    Numbness on short rides!

    I was doing 50 to 80 mile rides with no problem. Now I am limited to shorter
    rides, 5 to 15 miles a couple times a day.

    I never had a problem with numbness in the private parts until I started doing
    the shorter rides. It started almost at once, in the first couple miles. Just a
    bit of tingling and discomfort. The farther I went the worse it got.

    I figured out what was causing it yesterday.

    I have two bottle cages. one on the down tube, one on the seat tube.

    If I don't have a bottle in the cage on the seat tube it vibrates and makes
    the seat hum. The vibration is causing the problem.

    They are the aluminum wire cages BTW. If I put an empty bottle in the
    seat tube cage there is no problem.

    The frame is small and the bottle in the seat tube cage is a bit hard to get
    in and out, I used it for the spare bottle on longer rides.

    Stick in a picture so you can see what type cages and how close the spare
    bottle fits.



    The strangest things can happen on a bike!

    I know it may be perspective but that saddle looks Nose UP. The only part of the anatomy that should feel the saddle are the sitbones. If you can feel the saddle underneath then Blood circulation can be reduced- hence the numbness.

    But you may be right on vibration.

    I rode with an empty in the seat tube cage this morning and no numbness. If I tilt the seat down
    in the front I seem to always be moving back on the seat to get the right spot.

    I have done 6000 miles since April with the seat like this and only started having problems
    when I only take one bottle. I know this sounds weird!
