Cassette lockring issue

[Brucey]

Thinking about it, it is possible that, if the spacers are plastic, they may have swollen through contact with a solvent or oil, making the lockring unfeasibly tight.

I would have used the PSG method to destroy the lockring; this would have been much faster, and probably wouldn't have resulted in collateral damage to the 11t sprocket.

Noted. But still effectively nothing lost by using angle-grinder. I don't really use the 11t sprocket so the spares are effectivelly new. 8 speed, so cheap even if did write off a cassette..

Wish I'd done it before I killed the chain whip

(The cassette was not yet worn out......but it wasn't going on a tour with a siezed lock ring...plenty of spare lock rings and 11t's in the box of spares..... but some sprocket teeth are actually marked/ bent from the previous attempts at removal)

Fair enough. It was meant in jest.
Decathlon have a cool take on a chain whip replacement if you're considering a replacement for the broken one.

FWIW the decathlon tool is really only meant for removing cassettes, hence it only fits a few smaller-sized sprockets. The PSG method also uses an angle grinder of course, but it is very unlikely to create the same kind of collateral damage.
