Campa 10 speed 1x chainline
I am currently building an old-school gravel bike (if there is such a thing). Basically, I am taking an 80s cyclocross frame and equip it with campa 10speed ergopowers, a sram rd and a 42 shimano cassette. The crank is campa 10 speed 135 bcd square taper with a single 42t narrow wide chainring; no fd. The problem is the chainline. With a 102mm ISO/ITA chorus bb the chain sits, obviously, where the large chainring in a 2x setup would normally sit. In a 1x setup this is roughly in line with the second smallest sprocket. As far as I know there is no ISO bb with a 96mm, or thereabouts, spindle. Anybody with an idea how to bring the chainring further in? Help is much appreciated. Thanks!

I am clearly a complete idiot...Couldn't see the forrest for the trees. Thanks!

Also, if you haven't already, make sure your Campy shifters are compatible with the pull ratio of the SRAM derailleur.

It's an exact actuation rd, fully compatible. But thanks for the heads up.
