Anyone try these http://www.serfas.com/product_details.asp?ID=193? They look like they might do well with the bulge in the middle. I'm still trying everything to get rid of left hand numbness. Lower the seat, tilt seat slightly backwards, move seat forward, change handlebars, higher stem, several different kinds of grips, padded gloves, rotate brake and shifters down. So far nothing has helped, but then again I don't know how long it might take for a positive change to have an effect. I do know that if I don't ride at all for 3 days I still have the numbness
