I wanted to put some crusier handlebars on a Dahon or Downtube I've got my eye on to help with my health issues and allow me to lean back a bit .

My idea then was to put something llike electras bullhorn handlebars on one of the above , but was advised against by one of the uk stores , because they said it would " throw of the whole geometry of your bike "

Does any one here have any idea what they mean by that i.e. are they talking something to do with the balance of the bike / ride or more the cosmetics , as Im relatively a newbie , I cant tell.

Also , if this is indeed a bad idea i'd be interested to hear any alternative i.e. other handlebars that might be more economical for using.

thanks
