Maintenance of your bicycle is very important if you want to keep both your bike & yourself healthy. By keeping the your bike clean it’ll last longer, because the gravel & dirt that sticks to the different parts will eventually wear them down. Two days ago I changed the cassette on my bike because the cogwheels were worn down. While I was at it I also changed the brakes, brake wires & chain.
The first thing I did was to thoroughly clean my bike, but the photos of the cleaning were shot last year. I’ve added the photos so that those who are interested can see how to clean the cassette properly. It’s always good to keep your bike clean and especially when you have to make adjustments or change/repair different parts.
Here’s an attempt to explain how to change the cassette. To do this you’ll need a Chain Whip (Chain Whip – A metal bar with a short length of bicycle chain attached to it.):
- Place the chain whip around one of the largest sprockets to keep it tight.
- Insert the cassette key (with a ratchet or wrench) in the center of the lock ring.
- Force them together.
- When the lock ring is loose you can unscrew it.
- Pull out the loose sprockets and the cassette.
- Clean the hub that the sprockets have been on.
- Place the new cassette/cogwheels into correct position.
- Now, the instructions told me to tighten with the force of 40 Newton (I know! 40 Newton!?! I had to go to the bicycle shop so they could show me how much force 40 Newton is).
- Put the wheel back on the bike and remember to adjust the breaks (change the brakes & brake wire if you have to).
Remember to lube!
