Just how tight should I do up my cassette? Should I keep going when it starts making that horrible clunking noise or is that over doing it, I have done it for years but have a feeling I have been doing it wrong! no harm done it seems but how tight is the correct tightness? I have no torque wrench by the way. Sorry its such a numpty question. 😀

tight enough, but not too tight 😆

Every cassette I've ever fitted (and it's not that many) have had 40Nm marked on the lockring. I only work on my own bike so I've not really managed to develop a 'feel' for torque so do use a torque wrench. I don't know how 40Nm translates into 'feel'.

What clunking are you refering to, lockrings make quite a loud cracking noise as they're tightened. If your cassette is clunking as you ride something doesn' seem right.

Why ask if you have been doing it for years without problems? 🙄

Erm, buy a torque wrench and do it up to 40NM, that's how tight it should be 🙄

Nice and tight – the cracking is serrations designed to stop them coming undne – I wind it up nicew and tight with a big spanner. 40 nm is the equivalent of 4 bags of sugar on a metre long spanner. Quite a lot.

Cheers all.

brown or white sugar? 🙂

African or Jamaican sugar ?

Need 80 bags if its splenda sugar! 😛

The ones I've done have said "400kgfcm" – almost the same as 40Nm, but not quite – I think you're undertightening 😉
