If this needs to go to mechanics then boot it there but I thought maybe some of you may have encountered the same issue.
I have a '74 Raleigh International that I need to triplize because I am fat and the hills here are often steep. I am trying to run a period correct Record/Nuovo Record driveline. However I have modified it with a Red Clover triplizr and 28 tooth granny up front and the Soma long cage mod to the rear with a 30 tooth low.
Problems:
1. The chainline is 48 mm as Sheldon says to measure it and he shows a triple should be 45 mm. This makes it so my FD can [U]barely[U] make the throw with forcing it and then rubs.
2. My BB width is 123 mm (Campy Record with thin cups). However my smallest chainring teeth are only 3 mm from chainstay so I question being able to put on a narrower BB.
I'm reasonably sure that others have made this or something similar work but I can't figure out how to do it.
Thanks
