Numb fingers

[Trek1500]

Thanks for the feedback.

I don't have any neck or wrist issues but I do spend lots of time with my hands flat on top of the bars. I'll try moving around a bit more tomorrow. I wear the Pearl Izumi gel gloves as well. Interestingly, when I wear a full glove in the winter, the numbness doesn't happen. I can't wear those full gloves in this humidity, though, so I'll experiment with hand positions a bit more and see if that helps.

Try some other gloves as well. I wear Adidas gloves and find them more comfortable. Certainly move your hands around a bit as well. Tinglining is similar to cramping. You may need more electrolites especially now, when temperatures are getting higher.

Different gloves can make a difference! I was wearing the PI Gel Lite gloves. I found that the padding ran across my hand funny and was squishing a nerve that caused hand numbness. I now use the PI Gel Vent Pro gloves and they have made a huge difference, along with forcing myself to change hand positions often.

Have you ever noticed whether your fingers go numb when you are not riding? Like when you are cold or under stress? I have Raynaud's Phenomenon, which is a condition in which something triggers the blood vessels in the extremities (fingers, toes, hands, feet) to constrict, causing numbness (among other things). Although my RP is a hereditary rheumatic form, RP can also be acquired as a result of trauma and it is common to see in bikers who experience a lot of road vibration. Vibration triggers mine all the time. Good gloves help - I also have the Trek "buzzkill" ends in my handlebars and that seems to help as well. There isn't really a "test" for RP - just symptomology - but you might want to check with your doc if it is becoming a big problem. There are test for the various rheumatic conditions that can cause it. RP isn't necessarily dangerous in and of itself - but the one thing my doctor is adamant about is that I must never ever smoke (not that I would anyway, but apparently that can create havoc with RP because of tobacco's constricting effect)

You may want to check the angle of your saddle as well. If the "nose" is pointed a little too far downward, your body may be pitching forward just enough to put too much pressure on them. The slightly down nose position initially felt more comfortable to me, but it was leading to numbness in the hands.

I recently read an advice letter about the same thing and they said to check the position of your shoulders while you ride. Apparently where your brachial plexus (the nerves that supply everything to your arms) exits the base of the neck through the scalene muscles, can be affected by shoulder position. If you squash these nerves before they even get to your arms it can cause numbness. To relieve it we often sit up a bit and shake the hands around so we think its the hand position but it is often at the shoulder/neck. You wont be getting pain in the neck though as its just the nerves passing through the scalenes.
I get numb fingers on my upright commuter and had noticed it was more in the head-wind and when I was pushing it harder. My instinct is to hunch up my shoulders when I ride hard. I now make a conscious effort to relax my shoulders, even to pull them down, towards my waist and it has really improved.
Worth a try?

What the good Dok-Torrr said. Think about keeping your shoulderblades pulled down toward your bra strap and your sternum held up proudly. (get that lower trap working!)
