Well im getting a new chain for my bike its 18 gears and i looked on eBay it said 18 speed is it the same thing?
Bicycles have become a bit tricky over the years.
There are two different kinds of 18-speeds:
- One that has three chainrings up front and six sprockets at the rear.(3x6=18),
- One that has two chainrings up front and 9 sprockets by the rear.(2x9=18)
And a chain for a 6-speed rear won't fit on a 9-speed rear, it'll be too wide.
You MIGHT be able to run a chain for a 9-speed rear on a 6-speed.
Chains are quite cheap, so it doesn't make much sense to get one from ebay.
There are two things to think about when getting a new chain:
- the chain and the sprockets wear together, replacing only one often leads to chain skip and poor shifting
- you've got to get the chain length about right. Too short and you might burst your rear derailer, too long and you can get chain rub on some gears.
Chains are usually sold over-long, and needs to be cut to length with a chain breaker tool before being joined back together.
What else can I help you with?
What chain do I need for my bike?
To determine the chain you need for your bike, you should consider the number of gears on your bike's cassette and the type of drivetrain (e.g. single speed, 8-speed, 10-speed). Match the chain to the number of gears on your cassette for optimal performance.
How does the speed shifter on a bike work to change gears efficiently and smoothly?
The speed shifter on a bike works by moving the chain onto different sized gears, which changes the resistance and speed of pedaling. This allows the rider to efficiently and smoothly shift gears to match the terrain or desired speed.
What is the purpose of a bicycle chain tensioner in a single-speed bike?
A bicycle chain tensioner in a single-speed bike helps maintain the proper tension in the chain, preventing it from slipping or coming off the gears during riding.
How compatible is a 10 speed chain on a 9 speed cassette?
A 10-speed chain is not compatible with a 9-speed cassette. The difference in width and spacing between the gears on the cassette and the chain will cause shifting issues and potential damage to the drivetrain. It is important to use a chain that matches the number of speeds on the cassette for optimal performance.
How compatible is an 11-speed chain on a 10-speed cassette?
An 11-speed chain is not compatible with a 10-speed cassette. The difference in width and spacing between the gears on the cassette and the chain will cause shifting issues and potential damage to the drivetrain. It is important to use a chain that matches the number of speeds on the cassette for optimal performance.
How does the gear chain function within a bicycle's drivetrain system?
The gear chain in a bicycle's drivetrain system transfers power from the pedals to the wheels by connecting the front and rear gears. When you pedal, the chain moves along the gears, allowing you to change the resistance and speed of the bike.
What is the best way to maintain and replace a 10 speed mountain bike chain?
To maintain and replace a 10-speed mountain bike chain, regularly clean and lubricate it to prevent wear and rust. Check for signs of wear such as stretching or skipping gears, and replace the chain if necessary. Use a chain tool to remove the old chain and install the new one, making sure it is the correct length and properly aligned with the gears.
How do the bike chain and gears work together to facilitate smooth and efficient cycling?
The bike chain connects the pedals to the gears, allowing the rider to transfer power from their legs to the wheels. The gears, which are different sizes, provide different levels of resistance and speed options. By shifting gears, the rider can adjust the amount of power needed to pedal, making cycling smoother and more efficient.
How do the gears on a bike function to change the level of resistance and speed while riding?
The gears on a bike work by changing the size of the gear wheels that the chain is on. When you shift to a higher gear, the chain moves to a smaller gear wheel, making it harder to pedal but allowing you to go faster. When you shift to a lower gear, the chain moves to a larger gear wheel, making it easier to pedal but reducing your speed. This allows you to adjust the level of resistance and speed while riding.
What is the best way to maintain and replace a mountain bike chain on a 21-speed bike?
To maintain and replace a mountain bike chain on a 21-speed bike, regularly clean and lubricate the chain to prevent wear and rust. When replacing the chain, use a chain tool to remove the old chain and install the new one, making sure it is the correct length and properly aligned with the gears.
What are the various forces acting on bevel gears and worm gears?
Bevel gears can change the speed and motion and Worm gears can reduce speed and direction of motion.
How do you change bike gears effectively and efficiently?
To change bike gears effectively and efficiently, use the right gear for the terrain and your pedaling speed. Shift gears before you need to, anticipate changes in terrain, and adjust your cadence accordingly. Practice shifting smoothly and gradually to avoid straining the chain or gears.
