[#600237]

so is it absolutely essential i use a torque wrench to tighten the lockring when fitting a new cassette, or am i risking disaster by just guessing how hard to turn it?

I just tighten it until the blood flow stops in my fingers 🙂

Just tighten until it goes 'click, click, click' but before it goes 'click, click, click, click'.....

They really don't need to be as tight as the lockring says.

😆

Couldn't have put it better myself. When it goes 'click-CLICK-CLICK-CLICK-SCRUNCH' you've probably over-cooked it.

[wonders]

Is it actually possible to over-tighten a cassette lockring?

Yep, particularly on alu freehub bodies you can quite easily rip the threads out.

Yeah, careful not to strip the threads... From my experience, hope pro 2 alloy freehubs are made from cheap, low quality cheese.
if it clikclikcliks then stop! and get a steel freehub body!!

Three or four proper clicks (rather than zips which is does as it start to lock) is about right - it only has to be tight enough to not come loose while riding which isn't actually very tight.

it's going on a pro 2 as well... yikes. oh well, it's a good quality cassette (SRAM 990, the one with the red bits in!) so i reckon it'll be okay.

Nooooo! The red bits are wear indicators! If you can see red bits, it's already knackered.

I'm in need of a 'showing red bits' Sham 990 cassette, Don't bin it, I'll come and collect it off you. South Manchester I believe?

Mine say 45Nm! so I use a long torque wrench-less strain-takes seconds.

barca... yeah, i'll leave it on the wall outside ken fosters bike shop in chorlton for you mate. i'll wrap it up in £20 notes to keep it from rusting in the manchester "sun" too, ok?

buy a torque wrench? i probably will, eventually. don't want to get a cheap one though, and i can't shell out much cash on tools at the moment so i'll have to work round it for now.

good one's available for home / workshop use (3/8" drive) for about £30.
