numbness - left hand and foot(5 posts)

numbness - left hand and foot94Nole

Question about KOP and other adjustments. I feel like I am weighing too heavily on my hands, which may be contributing to my hand numbness but why only my left hand?

Also, I have experienced some numbness in my left foot. I have moved my seat around and adjusted and readjusted my handlebars.

For KOP, if my measurement is behind the center of the pedal, should I move the seat forward even if it feels weird?

Guess I am just looking for some ideas. And I have been to the LBS with no real improvement.

further offsets a 'balanced' posistion, resulting in INCREASED pressure on hands.

but it seems that if I got closer to the handlebars, I would have to bendover less thereby putting less weight on my hands. Why doesn't it work that way?

in front of a mirror, bend over at the waist. Watch what happens to your butt; it moves backwards. Also notice that you feel pretty comfortable in that position.

Now try bending forward without your butt moving backwards (you may need to lean against a wall). You 'fall' forward. Either you're very uncomfortable at this point, or you fell down.

Moving the seat back helps to 'balance' your weight over the bottom bracket, much like the first exercise. Moving the seat forward offsets that balance, much like the second exercise. You need extra arm support in that position to keep from falling forward.
Perfect illustration...94Nole

and thanks for the visual and the chuckle I got seeing it in my mind.
