Thanks. That is very helpful. The range of available derailleurs is daunting. Did you for the chainring onto a 2x crankset?
Are you converting an existing set up, or buying it all from new/secondhand?
If the former, it's really simple as all you really need to do is swap out the chainring for a narrow wide one, remove the front derailleur and shorten the chain.
Do you even need to shorten the chain?
It is to replace an existing 2x10 setup on my CdF.
