If you had seen my cues review in this forum I 100% suggested not to buy the poor quality u6000 parts. Cassette is solid though.Not sure on the quality of the derailleur and the shifter, but given how mine were working its an improvement at the moment. See how we get on with this.
The 10 speed deore linkglide mech and shifter work fine with the 48 cassette, despite Shimano saying max 43.
