OK, I have a 1974 or 5 motobecane grand jubilee. I was hoping to put a triple chain ring on it. (not as young as I used to be) I had been running a SR 110 BCD with smaller chain rings which seemed to fit OK (good chain line), but the left side kept coming loose. My question is will a campagnolo Mirage work on my set up? Some one gave me one to try, but the literature with is says I need a 110mm axle. Here is what I know about what I have. I know it has a stronglight BB, but I can not find any markings on it other than the axle length which is 118 mm. the axle drive side taper is about 2mm longer than the left side. The cups are loose bearing and right hand threaded.
Here is what I think is right. It is swiss threaded. It is ISO,aka Campagnolo.
Here is what I don't know. Can a 110mm axle be found that will work with my existing cups other than the uber expensive ones at Harris? Or is there some other solution?
Any help would be greatly appreciated.
Oh, and there are pix.
