How long should a bicycle chain be?
Using a ruler, a new chain should measure exactly 12 inches across 12 links, from middle of pin to middle of pin. The number most commonly agreed on for a worn chain is one percent elongation between links.
Do I need a shorter chain for a smaller cassette?
As the smallest cog and smallest chainring have not change changed size, the chain length will be no worse than it was previously. With the smaller large cassette cog, you may find you can shorten the chain, giving better small/small tension.
How can I tell if my bike chain is stretched?
Another ballpark method for checking chain wear is by measuring it with a ruler. Pick a rivet and line it up at the zero mark. Count 24 more rivets and your last rivet should be at the 12″ mark of your ruler. If it is off by more than 1/16″ your chain is stretched to the point of replacement.
How do I know if my chain is too short?
You should also see two slight bends at each jockey wheel of the rear derailleur. If the chain is too short, this shift is difficult to make and the derailleur cage is stretched out and almost parallel to the chainstay. If the chain is really short, then you might not even be able to shift into the largest cog.
Does it matter how many teeth on a cassette?
If you ride a lot of hills or struggle with hill climbing, a cassette with a lower ratio largest sprocket ( 27 or more teeth ) may be beneficial. It will allow you to keep spinning for longer, rather than grinding. When selecting a cassette for your road bike, ensure your derailleur can accommodate the largest sprocket.
Can I change cassette without changing chain?
Generally Yes you have to change your chain. The only time you might get away without changing chain is if its JUST been replaced. That is, under a hundred km of riding or in the last ~week. Running an elongated chain on a new cassette dramatically increases wear on the cassette.
Does chain length affect gear ratio?
The size of the chainrings has a subtle effect on all gear ratios. In contrast, riders that can push bigger gears at a lower cadence are more likely to prefer bigger chainrings. However, there is more to the effect of chainring size on the gearing of the bike than simply maximising or minimising roll-out.
How do I know what speed my bike is?
Multiply the front gear number by the rear gear number to get the number of speeds. For example, if you have two front gears and five back gears, you have a 10-speed bike. If you have one front gear and three back gears, you have a 3-speed bike.
Are 10 and 11 speed chains the same?
Since 10 and 11 speed chains are almost the same width, as well as cassette teeth, 10 speed chain can be used in stead of 11 speed one, without it jamming between the sprockets. However, this will still not work perfectly and will cause premature sprocket wear, so better to avoid it.
Chain Link Sizes: How to Measure Chain Link Sizes
- Pitch is measured by finding the distance from the center of one pin to the center of the next pin in line.
- Determine your side plate height and thickness by measuring both inside and outside the roller chain to ensure that you’re seeing a good average size.
What is a chain stay?
What is the chainstay? The chainstay or “stays” = The pair of frame tubes that joins the bottom bracket shell to the rear axle holders (the slots the back wheel goes in). This means that the chain stays connect the bottom bracket (BB) to the center of the back wheel.
