I have a 1x9 that I really dislike and want to upgrade. I was told to get a "Shimano Deore FC-M625 Double 2x10 Speed MTB Bike Crankset 38/24T" to upgrade my 1x. I additionally caught a branch on a downed log and twisted my rear derailleur, so I bought new Shimano Alivio RD-MD3100-SGS due to the Acera being out of stock.
The specs say 36T max low sprocket, but I wondered if I added the Wolftooth Goatlink could I upgrade to a 11x42T cassette?
I see the total capacity states 45T, so if I calculate correctly the 38-24=14 and the 42-11=31 (14+31=45) then I should max out at the 45T capacity. Am I on track with the increased cassette with this derailleur and the addition of the 2x crankset?
