I need to remove (open) a SRAM PowerLock link in order to replace the front derailleur. I have spent many minutes attempting to do so. When all else failed I resorted to Leonard Zinn's book. He says how it can be done but that it is practically impossible to do. I am sure some Slowtitchers have a technique that they will share.
Thanks.
Once, I was fast. But I got over it.
