I am looking for a bike to replace my current one, and I found one with a SRAM 12 speed eagle ttansmission. The thing is that I just changee the transmission on my current bike (9 speed Shimano CUES U400 cassete), and I was wondering if the 9 speed cassete from Shimano fits on that wheel hub.
The bike with tge SRAM transmition is a Trek Fuel EX 8 from 2020 if that helps answer the question.
