Just got back from a little spin around surrey but I have noticed recently that my little and 3rd finger keep going numb and getting pins and needles whilst I am on the hoods.
Does anybody else suffer from this, Its only just started happening, I havent changed anything...
If you don't already have, might be worth trying some mitts with Gel pads on the heel of the palm opposite the thumb... try raising your bars a smidge too
I get it quite a bit in my left hand when riding on the drops, just be a bit of ulnar nerve compression. I find it irritating, but its nothing sinister.
I used to get a bit of numbness/tingling. I now ride with a pair of Gore fingerless cycling gloves and problem solved. Also great for when it gets cold - even in the middle of winter, they keep your hands fairly warm.
Spesh BG gel gloves fixed it for me - I was getting numb hands after a 30km ride. Now, no numbness on a 335km ride. Some people swear by the gel pads you put under bar tape.
