hey so bought this new chain to replace my old one. only thing is a didnt have a chain tool,,,so after a long time with a hammer and various other tools i finally released i bent a link. so i bought a chain tool, removed the link, bent it back into shape and installed it back on the bike.

i then took it out to see how it was going and it was then that i realized that i needed a new cassette as well as the chain kept slipping. but at the time i thought it was a bit too long so i removed a few links with my newly acquired chain tool...and after more test runs it was confirmed.....i need a new cassette.

question is...i removed all those links and skewed the same pins back in...however ive recently heard that you have to replace with new pins every time you unscrew one!!. but is this true???
will i have to go round now and replace all the pins i screwed out with new pins.???????????

extra information.....(i did happen to notice metal shavings as i screwed some of the pins out but thought nothing of it).......also the chain tool broke so i got it replaced with a different one.

    If you have removed links how can you have put lots of removed pins back in? Did you rejoin it with a pin or use a quick link?

    When the chain is assembled at the factory the ends of the pins are swaged into the side plates. This prevents them from coming adrift in use.

    When you knock the pin out with a pin punch or a chain breaker tool, you usually shear off the swaged part of the pin (you might have a seen a thin ring of loose steel around the point your chain breaker entered the side plate). If you now refit the pin there is nothing to prevent the pin from walking out of the chain in use.

    Therefore the manufacturers have to supply a means for us to reassemble our chains. Most suppliers use a master link design, where the two halves of a special link are inserted into the chain and then joined together. Some master links are reuseable (e.g. KMC) while some are not (e.g. SRAM).
