My hands don't feel heavy on the handlebars, but the base of my palms gets sore after every ride on my Neko 3 hybrid despite 1) lightly padded Casselli gloves, 2) handlebar riser, 3) changed to swept back bars to open shoulder joints, 4) Ergo cork grips. I went into the bike store to see what else I should try. They insisted on a $275 fitting scheduled weeks out. After reading this thread, I'll try adjusting the seat position back.
