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.
I would like to know the hive mind/experiences before I go out and buy a width. Currently look at 700mm.
