Help! After 20 years of riding a Dutch bike I've just bought a flat handlebar bike so that I can go on long rides. After first few rides however my palms and thumbs became painful and now it looks like the tendons have swollen up on one palm. It feels like repetitive strain injury - stiff with shooting pains sometimes. I've adjusted the saddle height and started using padded gloves. It feels as if the wide handlebars may be forcing my hands into a strained position. - Will this improve as I get used to the different position or should I stop or change bikes ?
