Yes, you can mix SRAM and Shimano components on your bike. However, it is important to note that SRAM and Shimano use different standards for their shifters and derailleurs. SRAM uses 1x11 speed, while Shimano uses 2x11 speed. This means that you will need to use a SRAM shifter with a SRAM derailleur, or a Shimano shifter with a Shimano derailleur. You cannot mix and match SRAM and Shimano components without using an adapter.
