"chatter" is fine. i would love this freewheel to merely chatter when moving from cog 3 to 4. but it slides like the chain has fallen off a chainring. i think it might be pretty unsafe.

here's the ebay listing: Sunrace SR HG5B 5 Speed Cassette 24 14T Silver | eBay

i paid over $21 a couple weeks ago, and now it's $11.
