How to Change a Chain and Cassette with Rachel Atherton
Gee! This is ridiculous!
I look nothing like Rachel...
Joe I told you to SHHHHHH! Nobody is goimg to notice, it'll be fine!
Look at the state of me!
You look fine, crack on!
Go on get on with it! Just do it!
(In a girly voice) So, having used the chain wear indicator on this drive train,
it shows that this drive train is worn. So we are going to replace the chain and cassette.
(In regular voice) This is stupid!
I'm not doing it anymore!
Alright, get changed. I don't care, but nobody would have noticed the difference...you look exactly like her!
Anyway, back to replacing the drive train.
So to start of with I need to take out the rear wheel.
The easiest way to do that is to drop it down to the smallest cog at the back.
And then just undoing the rear axel here...
Taking that out and just sliding the wheel out.
Put the axel somewhere where you aren't going to loose it.
And then I am going to take the cassette off first, so for that I need...
My adjustable wrench, a locker removal tool, and a chain whip.
So once I have fitted this in place, hold that there...
place the locker removal tool in the end, and applying a downward force with both tools...
That just unscrews lightly, and remove the cassette in one piece.
There are a few loose bits in there so make sure you have got everything.
So taking the new cassette, popping this back on. Just make sure you line everything up correctly on the body.
Put the lock in, do the first few threads by hand.
Then taking your adjustable wrench and your locker ring tool, just tighten that up.
If you have a torque wrench you should use it and tighten it up correctly to 40Nm.
The second stage of this is to remove the old chain
so grab your chain tool and make sure the chain is pressed firmly down there
and the pin lines up with the pins on the chain itself.
Firmly twist that round pushing the pin all the way out, keep winding, it can be a bit tight sometimes.
There we go, so that's out.
Unwind the chain tool.
Take out the old chain by just pulling it out.
And now to fit the new one.
The easiest way to do this is to make sure we have both chains the same length...
line them up at the end and follow that down.
See the old chain there, this is the link we need to split it at.
Take your chain tool again.
Taking your new chain to fit it back to the bike.
Ensure that you go through tthe front derailer.
And then thread it through correctly on your rear derailer.
Make sure you go around the jockey wheels.
There we go...
Take your joining pin, which is supplied with the chain.
Take your chain tool and both ends of the chain, slide the joining pin in place.
Using the chain tool, push in that new joining pin into place.
Stop when you feel a 'click'.
If you have an excess bit to the chaining pin, then chop it of using the chain tool like so.
There you have it, your chain is joined!
So thats the chain and cassette replaced, that's you good to go.
