First time replacing a rear derailleur. Do I break the chain or remove one of the jockey wheels to get the chain off then on, with the new derailleur?
yep, this again...break it and replace it with a KMC type link...the Park tool also makes it a bunch easier. You can see the installed link a couple links to the left of the derailleur. You also can use them over again if you need to and there is no degradation in strength. It's pretty much a perfect world :thumbsup:Yep, this.
