That's what worries me with my new bars. I bought the contour pro tapers that have an 1 1/8" diameter where it mounts. These will be HARD to bend. You know, now that you mention twisting, I bet I twisted mine too. When I go straight it's like I have to turn the bars a little to keep it straight. It's almost like it's out of alignment if that makes any sense. I'm going to pull the stem, It's gotta be screwed.
Here's the new bars. Check out the first pic. You can see how the left side (right side if you're on the bike) is sagging compared to the right.
