I wrongly shorted a new 10-speed ultegra chain, measuring the chain lenght by big chainring-big cog technique I have just a half link of overlap instead of full link overlap. Any simple method for lenghtening (I'd need 2 more shimano joining pins?) the chain or should I just avoid this gear?
If you accidentally try to select the big/big combo, it can be very destructive, so don't do that. It's probably easiest if you just put that chain back in your parts bin for future use on something which needs a short chain and start again with a new one.
