changing a cassette

Postby k3vinjam3s » Wed Jan 09, 2013 16:35 pm

Gonna be changing my cassette and chain fairly soon and as I'm a total novice in anything other than cleaning my bike I was wanting some advice. Are they any special tools required to take of and replace the cassette?

Big adjustable spanner, the appropriate cassette lockring tool and a chain whip.

Easy peasy, have a look at park tools. Bear in mind it can take a lot of force to undo, best to arrange the two spanners hrozontally and push down on the wheel (tyre still inflated) in order to undo.

Or a lockring tool with built in handle but it's all the same.

Chain whip is an absolute minimum. If it's a Shimano 105 cassette or higher (Ultegra, Dura-Ace) you'll also need the right socket to fit in a half-inch drive to undo the locking ring. Slide the cogs off and make sure you don't lose any of either the cogs, the spacer rings or the metal spacer that sits at the back.

These are much easier to clean as all but the first 3 gears are individual cogs. Putting them back is just a case of putting it all back in the right order. If you get that wrong, give everything up. :)

Its easy peasy - even I managed it and do it regularly to deep clean the rear wheel as its so simple.

While you are changing the cassette over, use the time to inspect and relube your hub (If not sealed types) Though for that you would need a hub cone spanner too.

Yes straighforward, use the quick release to hold the lock ring tool in place until it starts to move when you are removing the cassettte. You can then remove the quick release and complete removing the lock ring.

Using the quick release holds the tool in place and stops it slipping off the splines.

I've started using SRAM chains and find them very good (they also come with the quick link).
