@Michal Peconka,

thank you for your help, but I would need the size chart for the bike wear not for the frame.

Regards, Katharina

Have bought a Sram Eagle GX 12v with Sunrace 11-50 12v to upgrade my DOWNEY 1.
The problem is the leg of rear derrailleur is not compatible and I'm very worried.
Have you any solution to give, please
