Road bike cassette and freewheel repair may well not seem like something that makes sense to you, what exactly are they?
Bicycle freewheels
A bicycle freewheel (often known as a block) contains a single sprocket or a group of sprockets attached to a body containing an enclosed ratcheting mechanism and mounts on a threaded hub. Put another way, a bicycle freewheel mechanism acts just like a clutch, making it possible to change gears up down.
Bike cassettes
Cassettes are distinguished from freewheels because a cassette has a number of straight splines that make up the mechanical connection between the sprockets and the cassette compatible hub, known as a freehub, containing the ratcheting mechanism. Again, in English, this is the part of the gears on the back wheel the chain goes around and moves whenever you change gears.
Bike cassette removal is not that bad - once you have decided to get your hands dirty, it's just a case of detaching the back tyre and taking it off. Bicycle cassette sizes vary from bicycle to bicycle, so if you're planning to repair the freewheel, it might be a good opportunity to get the bicycle cassette looked at as well.
Chainsets have one, two, or three chainrings, in ascending order from the easiest gear (the granny ring) to the largest ring. The combination of the quantity of teeth on the front ring and the number of teeth on the rear sprocket will give you the size of the gears.
Town bikes might have only one gear at the front, while racing bikes have a double chainset. The newest breed of compact chainsets make mountain bikes more manageable, and there are usually triple chainsets on mountain bikes.
Additionally, town bikes plus some mountain bikes can have a hub with internal gears, from three to seven speeds - they are the smaller gearsets on the back wheel, and the maintenance needed for these is minimal, though still necessary.
When chainsets degrade, the teeth become curved like shark's teeth, and also the gear shifting gets gradually worse, with the chain jumping off or slipping. Individual rings might be replaced, or you can replace the full chainset. Use a chain whip to undo the cassette, take out the lockring, clean the free-hub body, then slide on the new cassette, ensuring that you align the grooves.
