RockRider 520

[ Edited ]


I have a Rockrider 520, 2016. But now I want to change my cassete SRAM PG-820 (it is there as orginal) to SHIMANO SLX CS-M7000 11SP. But I need to know which hub is my rear wheel?


Is there anyone who could help me please?

I asked the store where I bought the bike but they don't know it...


Thanks a lot for help
