Other than the rear mech, I had changed rear wheel and bottom bracket so these could be the issue. My local bike shop have since changed the casset, chain and gear cable and still wont shift into largest cog.
Have you detached the cable to the RD when you try to manually push it into 1st gear?
is the issue the the RD can’t push the chain far enought inboard, or that it won’t clear the large cog (as if the cog is too big).
