25.8 versus 26 mm handlebar standard

I note that so handlebars are 26mm at the centre while others are 25.8 - are these one and the same standards - would appreciate a reply - thanks

 

Yeah. I think that you can pretty well mix and match 25.8 and 26.0mm stuff. I'd be cautious about using 25.4mm handlebars and stems.

 

Thank you for your imput - am replacing carbon handlebars ( stem will not work with it ) - may buy aero clip ons some of which clamp to a 26mm stem ) - regards to all
