Nobody asked the most important question----how much weight is bindibadgi putting on his hands? No amount of bar swapping and grip trickery will fix hand discomfort that's caused by bars which are too low. I had terrible numbness until I drank the Rivendell Kool-Aid and switched to a wide Nitto Noodle bar and got my bars up to saddle height.

Bindi---if you're having a bike fit, definitely mention your discomfort issues to the fitter. They will likely recommend you get the bars up.
