I've got a (new) KMC chain (KMC 1/2" x 1/8" x 114 L HV410) which I need to shorten in order to make it fit. The problem is that it's impossible to remove the chain pins with my chain tool… I've practically broken my hands trying to remove these things.
According to the KMC website I should be able to remove the pins with any regular chain tool so I'm not sure what I'm doing wrong. It does seem to push out the pin a little but then it just seems stuck and, try as I might, I cannot push them out fully.
Does anyone have any ideas? Am I doing something stupidly wrong? (bear in mind, this is my first time fixing up a bike so I'm fully prepared to hear that I've overlooked something basic )
Thanks in advance!
