A rear sprocket is almost always made of steel, as it has to stand up to a fair amount of wear from the chain. For bikes with multiple sprockets (AKA cassettes) you can sometimes find titanium sprockets to save a bit of weight on race bikes. They're horribly expensive and don't last very long.
On a bike there's one(or more) front sprocket(s) by the pedals connected by a chain to one(or more) rear sprocket(s) by the rear wheel. As the wheel isn't driven directly by the pedals, and there's usually a difference in size between the front & rear sprocket this constitutes a gear.
Chain is on the smallest sprocket on the crank and on the largest sprocket on the rear wheel
first. take the left side rear wheel off. then remove the 4 bolts that hold the sprocket to the sprocket holder. then remove sprocket
It allows the chain to transfer power from the pedals to the rear (drive) wheel.
The more teeth you have on the chainring(by the pedals) when compared to the sprocket(on the rear wheel, the more the rear wheel will turn for each turn of the cranks.
To provide power from the motor to the rear wheel in which to make it go
It's the small toothed wheel that the chain runs over by the rear wheel, although in engineering terms it is any toothed wheel designed for a chain, including the one rotated by the pedal and crank on a bicycle.
The chainring by the pedals and the sprocket(s) by the rear wheel.
yes but u will need a new swingarm,wheels,tires,rear brake line,and a sprocket
There are still rear wheel drives being made.There are still rear wheel drives being made.
It depends on whether you are talking about the front sprocket (the one at the pedals, called a chainring) or the sprocket at the rear derailleur. The lowest gear at the front is the smallest sprocket/chainring. The lowest gear at the rear is the largest sprocket. So if you combine the smallest sprocket at the front with the largest sprocket in the rear you have the lowest gear available on your bike.
Depends on if you're looking at the wheel or if you're looking at the pedals. 1st gear, the one where pedalling is easiest, is the biggest sprocket at the rear, and the smallest chainwheel at the front.
