Just upgraded an old 9 speed bike to 11 speed XT, all working fine. The chain came with a Shimano joining pin. I’ve used Sram quick links with my 9 speed stuff for years without any problems. Shimano always said their cassettes and chains were optimized to work together, but I’ve never had any problems mixing and matching Sram and Shimano chains, cassettes, quick links, etc. However, if the internet is to be believed, 11 speed stuff is different and Shimano quick links cannot be reused. Is there something magic going on here that means you can’t use a Sram quicklink with an 11 speed Shimano chain? Will it all explode into pieces if I ran a Sram chain on it?
