How does a freewheel work?
Mechanics. The simplest freewheel device consists of two saw-toothed, spring-loaded discs pressing against each other with the toothed sides together, somewhat like a ratchet. Rotating in one direction, the saw teeth of the drive disc lock with the teeth of the driven disc, making it rotate at the same speed.
What is the difference between freewheel and freehub?
Freewheel vs Freehub – Thread Differences
One of the main difference is that freewheels typically have a threaded hub. Bikes equipped with cassettes do not have a threaded hub, but instead, slip onto the hub with splines. But the differences, without getting too technical — go deeper than that.
How do you get a stuck freewheel off?
Quote from video: So I'm going to show you the trick to get those off. This particular one uses a Shimano tool with splines.
How do you remove a rear freewheel?

What is a bicycle freewheel?
The freewheel is a block of cogs that screws directly onto threads on the rear wheel. There is no need for it to be mounted onto a hub. It typically comes with anywhere between 1 to 7 cogs, and it is rare to find a freewheel on a modern bike. You do however find them on some new single-speed bikes.
What’s the difference between a freewheel and a cassette?
The freewheel is a single-unit and the act of pedaling tightens the freewheel to the hub. Whereas the cassette hub is a set of gears (cogs) that slides onto a cassette and is held in place by a lock ring.
How do you engage a freewheel?
Quote from video: You're able to easily move it or someone else is able to easily help you move it to re-engage the freewheel you're just going to pull down on the lever.
How do I know if my freehub needs replacing?
Check the freehub for wear to see if it needs replacing or just cleaning and relubing. To do this, firmly grab the splined body and give it a wiggle. If it moves more than a couple of millimetres side to side, replace it. Otherwise, a good clean and oil will do fine.
How do I fix the rear sprocket on my bike?
Quote from video: You want to fit the flat side against the sprocket. Put the lock ring on and tighten it by hand at first before using the lockring. Tool.
How long should a bike wheel spin freely?
You should be getting more than 10 seconds. One test for excessive drag is to watch the wheel as it stops spinning. It should oscillate back and forth two or three times as the heaviest section of the wheel settles to the bottom.
What is a wheel bearing?
What is a wheel bearing? And what does it do in a car? A wheel bearing is a crucial part of the wheel assembly that connects the wheel and the axle. It is a set of steel balls (ball bearings) or tapers (tapered bearings), held together by a metal ring. It enables the wheel to rotate smoothly with a minimum of friction.
How do you loosen the brakes on a bike?
Quote from video: It's not hitting on this either space on the side. So you can loosen this side I'm sorry tighten this side a little bit to bring it this way. Or you can loosen this side also to bring it that way.
