The size of these elements is the most important factor for calculating a chain length. Some chains are optimised specifically for improved switching performance and can only be mounted in one particular direction. There are also various chain types available for chains for mountain bikes and road bikes, which differ in weight and stability. The number indicates how many gears the derailleur can switch and the chain will need to be wider or narrower according to that number. The important thing to know is whether a chain is meant for 9, 10 or 11 speed derailleurs. There are various standard types that have developed over time. The chains are lubricated to improve the movement of the links and to make them more resistant to dirt. It consists of individual outer and inner plates that are held together with studs or bolts. The bike chain is the central element for propulsion.

Next we will look at why it is so important to have a well-fitting chain, how to mount it correctly and how to maintain it properly. recumbent bikes), where the chain gets rerouted again. This method also works pretty well on exotic bike types (e.g. Link the two ends of the new chain and voilà: a chain of the correct length is ready. Count four more chain links to the length and detach the links you don’t need at that point. Place the chain over the largest sprocket and the largest chain ring and bring the ends together without routing the chain through the derailleur. There is, however, a trick you could use if you haven’t got a calculator at hand. One way to be absolutely sure is to use our calculator to find the exact number of chain links needed. But what if you are building a new bike or you don’t have an old chain for reference? Now you know exactly how long the new chain should be and you can detach the links you don’t need. You can use either of these two methods: Take your old chain and lay it out next to the new one. All you need are a chain rivet or a chain lock and you will need to know the amount of chain links needed for a correct chain length. Ultimately, a tight chain on a motorcycle may break leaving you with no power.It really isn’t too difficult to get the chain length right. When a motorcycle chain is too tight, it’ll put stress on several components of the bike and cause the sprockets to wear faster, make the engine work harder, and cause the suspension to be tight and uncomfortable. A chain tensioner can make the process easier. Then, loosen the opposite axle-nut, adjust and tighten, making sure the wheel remains centered in the frame. To change the tension loosen one of the axle-nuts and move the wheel forward or backward slightly and snug it up again. Shift down into the smallest ring in the rear cassette again, and press your shifter again to see if the bike shifts properly. They can also stretch over time as you ride. In the first half dozen rides on a new bike your shift cables stretch the most. Most of the time, a skipping chain is caused by cable stretch. For two-sprocket or single speed bikes, replace your chain as it reaches the 1 percent wear mark. If you are using an eleven or twelve speed chain, replace your chain once it has reached 0.5 percent wear. If you are using a chain designed for ten or fewer gears, replace your chain as it nears the 0.75 percent mark. The chain might skip as you pedal, or even drop off the gears. A loose chain will sag close to or below the chainstays as the chain hangs between the rear cogs and chainring. To find out whether your chain is too long take a look at it from the side with your eyes being level with the chain. The chainring, derailleur, or the chainring are damaged. Your front and rear derailleur are not properly aligned. As a result, the chain may keep slipping off. If the bike chain is too long it will cause problems when changing gears as you shift gears and the derailleur can’t pick up the extra chain length.
