PhilDAS-
No master link, just a normal chain. To be exact it's a Deore CN HG54.
First time it snapped it completely blew apart, pin flew off somewhere.
Today, as you see in the photo, it just seems to have popped open.
I made 100% sure I didn't make some kind of user error with putting the chain back on, because I assumed I might have somehow done this the first time. Now I'm pretty sure I didn't. Also, I've put chains on and off bikes more times than I can remember and I've never experienced a snapped chain before.

Big dredge.
My new chain has snapped twice in the last 3 days. First time I pulled out a link and sacrificed the lowest gear, today I've just binned the chain. Does anyone know why this might be happening? The chain was not under any crazy torque, just normal relatively slow commuter cycling. It's a 1 x 10 and it looks like everything is nicely lined up. Cross check, 10sp deore rear mech, grx cranks.
