3T Ergonova team stealth carbon handlebars. Very stiff and VERY light at 202g on my scales. Internal routing slots. Spec here: https://www.wiggle.co.uk/3t-ergonova-team-stealth-carbon-handlebar-1 Note: 3T call these 44cm wide but this is at the drops - they measure 42c-c at the hoods. A few of the usual scratches. Thanks for looking.
