What is 8 speed bike?
In a Hub Gear system, the gears are enclosed within the bicycle’s rear hub.
When “3 Speed” or “8 Speed” is mentioned in relation to a hub gear, it means that the hub has 3 (or 8) distinct gear ratios..
Can I use a 8 speed chain on a 7 speed bike?
Chain As you go to more sprockets on the cassette, you need a narrower chain. However, using a chain one size narrower than standard rarely presents any problem. Thus, you can use a “9-speed” chain with a 7-speed or 8-speed system, or a “10-speed” chain with a 9-speed system.
Are 8 and 9 speed chains the same?
7, 8, and 9 speed chains have the same inner width, but 9 speed chains have thinner outer plates for a thinner overall chain. So while a 9 speed chain works fine on a 7 or 8 speed drivetrain, it will be a weaker chain that tends to “stretch” faster.
Is a cassette better than a freewheel?
When you’re simply cruising along i.e. not pedalling, or going backwards, it spins freely. A cassette is the more modern option and has quickly overtaken the freewheel. It comprises a collection of independent cogs set on layered rings that come apart and slot onto the body of the (also more modern) freehub component.
How do I know if my chain is worn?
There are different methods for measuring chain wear from simply lifting the chain off of the front chainrings to measuring the distance between two rivets on your chain. But the easiest and most accurate way to determine chain wear is by using a tool such as the CC-3.2 Chain Checker or the CC-2 Chain Checker.
Why does my chain skip when I pedal hard?
Most of the time, a skipping chain is caused by cable stretch. In the first half dozen rides on a new bike your shift cables stretch the most. … To fix a skip in the rear derailleur, shift your chain into the smallest ring on your rear cassette (the hardest gear) and the middle or larger ring on your front derailleur.
What is a 3 32 chain?
3/32″ (0.094″, 2.30 mm) chain is used on derailer equipped bicycles that have more than 3 cogs at the rear. Even somewhat narrower chain, typically . 090″ or 2.29 mm between the inner plates, is used for derailer-equipped bicycles with 9 or more sprockets at the rear.
Are 7 and 8 speed cassettes interchangeable?
A 7 and 8 speed cassette have the same amount of space between each cog. An 8 speed cassette is slightly wider than a 7 speed cassette because of that added gear. … Simply put – 8, 9, 10 speed cassettes all fit on the same hub. A seven speed cassette will fit on an 8 speed freehub with the use of a spacer.
When should I replace my 8 speed chain?
The number most commonly agreed on for a worn chain is one percent elongation between links. In reality though, you want to replace the chain before this point. So therefore anything past 12, 1/16 inches (0.5 percent) would be the time to replace a chain.
Can I use a 9 speed derailleur on a 8 speed?
yes you can use the derailer on the 8 speed cassette. The major difference between 8 and 9 speed is indexing. So for an 9 speed cassette you would need 9 speed shifters.
What chain should I use for single speed?
Although geared bikes use the much more common 3/32-inch chains, you’ll need a ⅛-inch chain if you’re riding a fixie.
