The reviewer discusses installing and testing the EC90 handlebars on their bike. They initially mention putting these bars on to test for flex, then proceed to perform a pressure experiment where they observe significant flex when weight is applied. The reviewer expresses surprise at the amount of flex, noting that it wasn't apparent when the bars were off the bike. Ultimately, they decide not to use these handlebars on their bike, opting instead for Specialized S-Works bars.
