I purchased a new KMC DX10SC 10-speed 114 link chain to replace my worn out chain. I'm running a mountain triple and it seems that The chain is slightly too short at it's full length. I can't get in the big ring on front chainring and rear cassette at the same time. I don't necessarily want to ride like that (terrible crosschaining), but I would prefer to have the capacity to do so since If I shift up to the top of the cassette it locks the derailleur in to place due to the tension and I can't shift out of it.
So, can I simply push out the pin and add a few more links and re-join it the same way? I'll have to buy another chain presumably to extend it or find some spare 10-speed links. Is this something that causes problems with 10-speed chains or can I do it the same way I've always done with my 6/7/8 speed chains?
I figure my alternative is to get a short patch of chain and use a couple KMC missing link quick links to join the sections together.
