Review on JGbike 10-Speed MTB Groupset for Shimano Deore M4100: Right Shift Lever, Long Cage Rear Derailleur, 11-42T or Sunrace 11-46T Cassette, KMC X10 Chain by Christian Young

I already had an XT color and rear derailleur so I really didn't want to buy new derailleurs/shifters to ride 1x on my MTB so I went down that route. I chose this cassette over an all-steel cassette to save some weight and the aluminum cross should protect my freewheel body. etc. I made a long B screw, but at this point you only have about 1/4 of the cog with the chain. The chain and cassette should give me a better life. I don't have that many miles on the cassette yet, I'll let you know if I run into any major issues, but after a few quick test rides it shifts fine. UPDATE: A few rides on the trail and I'm hooked. The best upgrade I've made to my MTB. I really like the 1x setup. There are no shifting problems.
