^ mine didn't have the nano-technology and I made sure the dust was kept wet/lubricated so none was airborne (to my knowledge) I also did this in my garage with the door open. Sorry to ask all of these questions, but the front brake handle I had on my bullhorns is too large for this easton bar which is about 22-23mm diameter. the handle is 2-4mm too large. where should I go about buying a new one
