I have a Giant 2013 TCX Advanced. It has a Rotor 3DF, 36/46 Crankset and a SRAM XG1190 11x28 cassette. I'd like to swap the cassette for an 11-40 or 11-42.
The guys at Wolftooth said: "..derailleur does NOT have enough capacity to handle an 11-40 cassette and a double chainring. You will have to be careful to not use small/small and large/large gearing combinations.."
Can I simply buy a new long cage derailleur, such as Sram Unisex's NX 1x11?
Thanks David and..Ouch! Never realised that! So, to keep it relatively simple (and less expensive): my best choice to get to at least 1:1 is to replace the 36 crankset with, say, a 32 and the cassette with an 11-32? ...Again using the roadlink from Wolftooth? Do I need to replace the short cage? Can I replace the 36 with a 30... (and install the 11-32 cassette?).
