I have been fighting some numbness in both my hands for a while and sometimes only after 15 or 20 min ride. I started to figure out the cause when i was on a long ride with a group and the numbness got pretty bad. Once I pulled my elbows close to my side I started to feel some relief. I noticed once I stopped that my hands were being pressured only on my palm under my pinkie finger. I felt that the stock sweep was a little too much for my riding style. I found these carbon looking bars
BellissiMoto – Driven Aluminum and Carbon Handlebars that had less sweep in the super cross bend than the stock bars. I took a chance and it has really paid off. With the combo of some gel grips and the new bars I had a hour long ride yesterday with not a hint of numbness.
