Pretty much all steel bars will have a cross bar making the stiffer then stock and less flex. Aluminum bars can be found without a cross bar making them more compliant. They don't have vibration issue. At least mine don't and good grips like a true dual density like Spider lessen any there may be. I like mine very much. They are 1.125" but easy to find various conversions from 7/8.
