Your handlebars greatly effect the feel of you bike and how you bike handles. Sometimes bars that are comfortable for long rides aren't the best for bike handling.
Mountain Bike Handlebars with a lot of back sweep (back sweep is how the handlebars point slightly back towards you, all mtb handlebars have some back sweep but most ae between 3 and 9 degrees, these bars are 11 to 37 degrees) hurt your bike handling!
Have your ever ridden an old 3 speed with bars that bend straight back towards you? They are very twitchy. These new bars are similar. The more back sweep a bar has the more it moves your elbows in, towards your body. This puts you in an nonathletic position (elbows in) where you can not resist side to side bar movement nor can you move quickly or efficiently.
If you were thinking these type bars might be an upgrade, they are not! As we have stated before, look for a wide bar, 720mm to 810mm and a short stem, 30-70mm long and you will have much more control (assuming you understand and ride in proper body position).
Create you most in control ride yet!
