SRAM NX Eagle DUB 12-speed sau Shimano DEORE M5100 1×11-speed

Salut, detin un mtb Specialized Rockhopper Comp 29, 2x si vreau sa ii schimb transmisia, dar aici nu stiu daca este diferenta asa de mare  dintre cele doua transmisii cum este si pretul:

SRAM NX Eagle DUB 12-speed Group 11-50T Boost 175mm   avand un pret de achizitie de 280 euro

vs

Shimano DEORE M5100 1×11-speed Upgrade Kit 11-51 avand un cost de achizitie de 110 euro la care se mai adauga si pedalierul DEORE FC-M5100-1 10/11-speed Crank 32T care costa 47 euro.

Intentionez sa le achizitionez de pe :
