changing cassette...

Infamous

Put on a new chain, quickly realised that it needs a new cassette, i've never done this before so have some simple questions...

It's 8 speed, will any 8 speed cassette fit?

What tools do i need? I know I need a chainwhip thing, but what about a lockring?

thanks.

Make sure you get Campag or Shimano specific. I believe the locknuts need a different tool(?). Replacement cassettes for Shimano can be had from Sram, or Shimano of course. Not sure about Campag.

You need a chain whip and a lockring nut. Should come off ok but have to admit mine was a right bar steward. My 8 speed had an HG50 cassette and it's fine.

You'll also need a torque wrench to make sure you tighten the lock ring up the right amount.

you don't need a torque wrench, just a chain whip and a lockring socket

thanks guys, apreciated.

Will an adjustable spanner work with the lockring?

ACMadone

Yes it will work. I use one on the lock ring whilst the chain whip holds onto the cassette to loosen it.

Take a look at the above - got them a few weeks ago and find them very handy
cuts out the adjustable/spanner also price reasonable Am not connected with seller!

Good call, that makes it a lot easier

We have tighten lockrings far before torque wrenches became fashionable, he doesn't need one at all.

Yes but you still need the lockring tool (nut) Shimano or Campagnolo, they're different. You can find it in any bike shop online

Look here also - A little cheaper and probably quicker

If your drive train is Shimano or Sram it will do, if it's campagnolo probably not. You still need the lockring tool, don't know about SRAM though, but it has 12 "teeth" and looks like the Shimano one.

Beware that the lockring tools for Shimano and Campag look almost identical but are not interchangeable.

Use a big adjustable spanner to get a decent amount of leverage - you don't need a torque wrench, just do it up quite tight, not quite as tight as you can possibly manage, but almost. It will make little clicking noises as you tighten it, this is normal.

yeah sorry it's a shimano.

You're quite right. They're such a new fangled thing and I've never seen a good bike mechanic using one................... <glances at his 20 year old torque wrench on the shelf> :?

There's a reason they write the torque settings on the lockrings and if you're going to look after your bike properly then it would seem odd to not tighten it the right amount. It's obviously your choice but I prefer to look after my bikes in the best way I can.

If it's really tight you can use a socket driver with a spark plug socket on the lockring tool. No need to tighten the new cassette that much though.

Infamous

Got the lockring tool, haven't had chance to get the chain whip yet...

maybe a silly question, but do you really need a chain whip? it's just a bit of chain on a stick isn't it? Can't I just use an old bit of chain ?

John.T

Back in the old days we used an old chain and a claw hammer. I have since made one from an old chain and a bit of 1" by 1/8" steel strip.

aracer

Yeah, but you'll need to attach it to a stick to get enough leverage (I homemeade one, but not sure it's worth the hassle when they're so cheap).

Infamous

again maybe a stupid question, but how do I remove the plastic bit in the middle?

as seen http://www.sram.com/en/srammountain/cas ... /pg820.php

unscrew the lockring somehow? the tool doesn't fit over the plastic.

Infamous

disregard that, I just put my thumb through it


ow

mostly harmless

Before I got a proper job and had money to spend on such frivolities as a chain whip I used to hold an old off cut of chain in a pair of mole grips which worked just fine. A mate of mine who had neither chainwhip nor mole grips used to put an old chain in a vice, stand the wheel on the bench and undo it that way. Both methods worked just fine, a chain whip is nicer but it's an extra tenner, it largely depends how flush you are and how developed your tool fetish is.

Regarding a torque wrench there's nothing to stop you using one but after you've done a few you'll get a feel for how tight it should be. It's not one one of the critical things you must use a torque wrench for.
