Bought a chain with a master link (packaging said quick connect link), it looks just like this:
This bit however won't fit cleanly through my derailleur, it snags on the wall right as it goes onto the first jockey wheel:
First off I tried adding a washer to widen the clearance between the derailleur plates. This helped a little but I can't add any more washers because the screws ain't long enough. I've tried reversing the direction of the master-link plate, won't work because it hits the cogs. I've also adjusted the high and low screws of the derailleur, to no avail.
I'm afraid that if I try to file down the pin it will make the chain more prone to failure. Wouldn't it be better to bend the derailleur plate out of the way somehow?
Am I missing something here, did I install something inappropriately or pick a wrong part?
EDIT: The packaging of the chain says 1/2 x 1/8 / 114L, suits most geared bicycles :D
