it "clips" to either side of the stem.... so that part on most handlebars is round anyways.... i also have the bigger around ones (31.8 i think??????) mine are slightly flat were i hold them... but round where the stem holds them... and where this bag holder goes!
and by using clip... let me amend... it SCREWS on! it goes around the bar.. either with or without the rubbyer stuff (hubby had to use something less thick than what they supplied... would have to aske him what!) that acts like a... uhm.... washer/griper... then you screw it one!
i really need to take pics tonight for you guys!!!!!!!
here's a link to my bars
