On this particular one, I noticed they (the
high gear sprockets) were somewhat rotatable
just fiddling with them, but far from spinning
like a wheel or pulley.

I didn't look for spacers but the casette is
brand new - Sunrace 8 11-32t.

(there are other possible issues, such as 11t
sprocket on a pre-11t body and so on)


Very interesting, the wheel and thus body are
used stuff, I don't know how old. Is it too
late to examine without having to remove the
cassette? Still, could be useful next time...

By the way, this notation, are the rest of the
sprocket sizes deductible from it? The casettes
look all symmetrical to me...

Hello again everyone!

Now I've moved on from the Swedish and
Norwegian standard bikes of the 70s into the
most recent of bike technology, namely the
mountain-bike or "MTB"!

I read on the cassette that you should pull it
40 nm. There is even an arrow pointing the way.
It is the well-known way, but OK.

I know there is a tool for this - torque
wrench, right?

I don't have one, but I do have the everyday
half-inch ratchet, and the special socket with
all the teeth (?) -
of 40 nm, I know only this is a lot and the
reason I know this is every time I remove it, it
is stuck like, very firmly!

When I pull, I hear a crash sound three or
four times. This seems to be normal.

I asked the local guru who did bikes since the
80s. He also claimed he was a master after only
two years. Anyway he suggested it was sand!
But I'm not that stupid I don't make the parts
rudimentary clean before I operate them. So it
is not sand. Besides the sound is much to big
to be sand.

Anyway what do you guys make of all this?


Get a torque wrench and tighten it to 40nm.


I have a couple of torque wrenches, but my cassette took does not have a socket wrench fitting -- so I use a adjustable wrench. Go ahead and hate on me, but I just give the lock ring a good yank. With the serrations, loosening is unlikely. But now I feel bad and will go out and find a tool with a socket wrench fitting.

After cleaning threads, seat. Lubricaton with loctite n the assembly does. not snug down tight try measuring the space between nut and cassette...feeler gauge.

Ask the LBS for that spacer

I advise you not to listen to anyone else on this subject except Al Muzi.

You don't need a torque wrench but it's nice to have one and the adapter to work with your cassette key.

Otherwise tighten firm and not real tight. I think that the "crash" you're talking about is the serrations/semi-ratchet teeth on the inside of the lock ring. These are to keep the lock ring from backing off if it isn't tight enough.

The cassette should NOT rattle. If it does there is an incorrect spacer.

I assume that you know the difference between a freewheel and a freehub.

If you have a vernier caliper you can measure the spacers and let Muzi know and he can straighten things out.

I've tightened many a cassette lockring by use of a large adjustable wrench.. I just push on the wrench until the lockring stops clicking. I've NEVER had a cassette lockring come loose even those ones I've put on over a cassette with the last cog having no serrations. I just snug up the lockring on those until it feels tight. All of those cassettes were ridden for many rides of 100 kms or more.

Cheers

There are serrations on both the last cog and the lockring. When you tighten the lockring at first you'll hear a number of clicks as those serrations engage each other.

Cheers
