Shimano Deore LX T671 48t 104mm 10-Speed Outer Chainring

Hello friends good afternoon, nice to greet you, I would like to know if you can help me with something. I have a 2013 RZ120 One Twenty 2 .. it comes with the specifications described here (Shimano M552 with 42x32x24 plates mounted on the narrow bottom bracket of the Cannondale of only 68 mm wide. 10 rear crowns with Shimano derailleur and derailleur buttons SLX and Deore XT rear derailleur) Recently I acquired a Shimano Deore LX T671 48t 104mm 10-Speed ​​front plate .. for the moment of installation it presents me problems with the changes since it does not engage the speeds, it is rubbing the chain to the derailer front .. apparently the curve of the same is not very pronounced and the path of the same is also short which prevents moving the chain normally and make the change cleanly. My question is ... should I change the front derailer? If so, what would be the ideal to be able to put this 48T dish to work correctly.Thanks in advance for your valuable help

Changed out my 42T for 48t chain ring on my e-bike. Much better pedaling cadence in the higher gears. Highly recommend.

Good and not expensive chainring

Very nice replacement for my 42t Shimano chain ring
