I've got a drive train of athena from the late 90's. I wanted sti type shifters .I liked the hard crisp click of Campy. I've sense returned to Shimano DA stuff. The Campy stuff I've got works great,never a problem. I've got a riding bud he likes his stuff He's got late 90's Record & Choris (or how ever it's spelled). The Bearing groups of Campy are great.
