First, sorry if this has been discussed before. Time is pressing and I can't search for a similar topic.

My Shimano 105 chain broke when I was riding in the mountains and I fixed it on the side of the road by removing a link pair. Is it okay if I keep the chain shorter than before or should I add a link pair to replace the removed one?

When the chain is on the big ring + big sprocket, the S-turns at the derailler are very pronounced, which makes me think that the shortened chain is ok.

I'll visit the LBS tomorrow to true the wheels and ask them about the chain as well, but I'd like another opinion, as well, so that I won't spend the money for nothing.

Btw, this is the original chain that came with my bike and it is not stretched at all.
