I can’t believe Giant’s response or that this is normal.

If the high limit screw that far off, the rest of the cassette wouldn’t index correctly. The indexing is from the 1st position cog.

I suppose it could be a missing/wrong DS hub washer, but a chain should never run against a dropout.

How could it get out of the shop?
