I got the El Guapo stupidly wide ones from PX. They are 760, according to the email confirmation from months ago. I found them ‘kind-of’ wide. They felt wiiiide for the whole of five minutes and after that just normal. That’s the singlespeed rigid mtb though. They were way too wide for traffic.
If you're uncomfortable with your hands at the outer ends of the bars, they are too wide.
