[Gwerziou]

I run a long-cage 'titanium' Record 10-speed rear derailleur with 2014 11-speed shifters and it works perfectly - I mean, really great. I use an 11-32 cassette. On the front I have an old 110 BCD cold-forged crank with Specialites TA 48/34 chainrings - works perfectly. The front derailleur can be either a pre-2015, a post 2015 'long arm' although I found the throw on those was a bit too aggressive and could throw the chain off more readily, or a Record triple or racing triple. The crank I use is nominally a triple although I use it as a double, and the Record triple 10-speed front derailleur I use works like a charm. I also have an old Record OR triple front derailleur in perfect condition that I am going to test just for kicks along with an incoming NOS/NIB Euclid crank, used as a double with the TA chainrings.
