adjust the bars til they feel better

I hate the bars on my new MTB compared to my road bars. I twisted the bars a bit and it helped quite a bit. The way the mechanic at the bike shop set them up, swept a bit up and back, all of the pressure on my hands went to the outside of my hand rather than the entire hand. I found it more comfortable to have the bars swept a bit down and back.

Fitting your bars has a lot to do with your torso height, shoulder width, riding style, etc, etc. It takes a while to dial it in perfectly, and you know best what to do if you pay attention

Keep tinkering adn you will find a lot of improvement.
