David Bender
Shimano chain

Chain has a stiff link I can't get to loosen up. It's causing the chain to skip on the cassette.
Disappointed in shimano QC to release a bad chain.

Dante Santos
New chainring- new chain

Replaced my old chain since I got a new chainring. This one feels way better than the one I was running. Will buy again.

Thomas Martin
Shimano M6100 chain

Have sram nx and changed cassette to shimano microspline. This chain has performed fantastic and shifting is excellent especially under load with no skipping at all
