Sometimes you have to remove the cassette with rear sprockets in order to adjust the bearings of the rear hub (by and large, you can not remove it, but it is more convenient to adjust with the cassette removed). Sometimes it is necessary to replace the sprockets themselves or replace the rear wheel spokes on a trip. This can be done on your own with some special tools that every self-respecting cyclist should have.
Instructions
Step 1
Remove the rear wheel. To do this, turn the bike upside down and support it on the handlebars. If you have an entry-level bike, the wheel is secured with nuts that are screwed onto the ends of the axle. Use a suitable size adjustable wrench or spanner to remove the wheel. If you have a sports road bike or mountain bike, then an eccentric clamp can be used. In this case, the wheel can be removed without tools.
Step 2
Insert the cassette remover into the slotted nut. The cassette is attracted to the ratchet by a slotted nut. In order to unscrew this very nut, you will need a special cassette remover (can be purchased at any specialized store). And to hold the cassette (you have to unscrew it towards the free rotation of the rear wheel) you will need a whip. Also get an adjustable or box wrench.
Step 3
Place the whip on the largest cassette sprocket. Hold the cassette with a whip and rotate the stripper with a wrench. This will take a pretty decent amount of effort. Please note that the smallest sprocket and spline nut have a slightly corrugated surface (so that there is no spontaneous unscrewing), therefore, a sharp crunch will be heard during unscrewing. Do not be alarmed, this is normal.
Step 4
Unscrew the nut completely, then remove the cassette. Keep in mind that some small sprockets can be independently put on the ratchet, and there are washers - spacers between them. Carefully remove these washers and sprockets so that they do not fall apart during disassembly. Take them off one at a time and lay them out neatly somewhere, so as not to be confused during assembly. Then remove the cassette. After that, remove the protective plastic ring, which is on absolutely all cassettes.
Step 5
Take a close look at the sprocket teeth and determine the degree of wear on the cassette. After removing, cleaning or replacing necessary components, reassemble the cassette in the reverse order and install it on the rear wheel of the bicycle.
