How to calculate chain size?
Largest Cog & Largest Chainring Method For bikes with rear sprockets that are a maximum of 36 teeth or smaller, the common method is to measure using the largest rear sprocket and largest front ring as a reference. Two rivets (one inch) are then added to determine final chain length. Once the zero position of the chain is set on the rear part of the sprocket, you can determine the final chain length. You do this by adding the number of used chain links to the zero position. It also matters whether the zero position ends with two matching or two different links (see chart).Largest Cog & Largest Chainring Method For bikes with rear sprockets that are a maximum of 36 teeth or smaller, the common method is to measure using the largest rear sprocket and largest front ring as a reference.

How to find out what size chain to get?
First, wrap the ribbon around the base of the wearer’s neck, and mark the spot where the ends meet. Then, lay the ribbon against a yardstick or ruler to determine approximate neck size. After a measurement is obtained, its a good idea to opt for a necklace size that is at least the second size up from your neck size. A 16-18 inch necklace is perfect for everyday wear for women, while a 20-inch necklace is suitable for males. These lengths fit perfectly from the base of your neck to just below your collarbone and look great with most outfits. The ideal length may also be defined by your unique style.After a measurement is obtained, its a good idea to opt for a necklace size that is at least the second size up from your neck size. For example, if you have an 18 inch neck, you should probably choose a chain length of 20 inches or more. An 18 inch chain would feel too tight.Average woman’s necklace lengths range from 16-20 inches, with 18-inch necklaces being the most popular. The average necklace length for a man, on the other hand, stretches out a bit further and ranges from 20-25 inches.
How to choose tire chain size?
The first number following the P is your tire width in millimeters. The second is the height ratio of the sidewall compared to the width. The third is the wheel diameter in inches. But really all you need to know is the full number so you can match it up with the right tire chains. Size designation The first part of the tire code specifies the width of the tire in millimeters, followed by a slash and the aspect ratio, expressed as a percentage of the width. For example, a 215/55R17 tire would be 215 millimeters wide, with a sidewall height that is 55% of the width.
What grade chain is strongest?
Grade 100 chains are the strongest among readily available chains. Their strength-to-weight ratio is about 25% higher than grade 80 chains’. Most of the time, a grade 80 will suffice. However, you may need a grade 100 if the chain’s application is heavily concerned with the strength-to-weight ratio. Grade 80 chain is a heat-treated steel chain with a high strength to weight ratio. Its strength makes it safe for overhead lifting and lifting slings. It’s also excellent for uses such as recovery, safety, and towing chains.Grade 70 – Grade 70 chains are about 20% stronger than grade 43 chains and made from heat treated carbon steel that provides excellent strength and durability. They are commonly used for trucking and trailer tie downs, heavy load securement, and heavy towing.The preferred chain for load securement is Grade 70, but any grade of chain can be used for tie downs or tensioning. You have to know your tensions in order to select the proper chain.
Is a 40 or 41 chain bigger?
The only distinction that exists between a #40 and a #41 roller chain is their inner plate width, which for #40 is 0. This one difference determines their best use cases, wherein #40 is for heavy-duty while #41 is for precision. Dirt bike chain sizes are based on standardized measurements. The numbers (like 420, 428, 520) refer to the pitch and width of the chain links. The first digit refers to the pitch (distance between pins), measured in eighths of an inch. The last two digits refer to the internal width of the chain.These are all based on the 5/8-inch (16mm) pitch; and are normally known and referred to by the prefix “5” (ie 5 eighths of an inch). The smallest chain in general motorcycle use is the 520 – the internal width between plates is also based on 1/8 inch. So the “20” refers to 2 x 1/8 inch = 1/4 (6.The first digit (e. The last two digits (e. In short: 420 chain = Pitch 12. Inner Width 6.Size refers to the pitch (length) and width of each link. There are two common chain sizes that likely cover everyone: #50 and #60. These sizes refer to ANSI (American National Standards Institute) Roller Chain Standard chain dimensions.
