How To Measure A Replace Single Bike Chain?

Measure the length of the chainstay and multiply it by two to get the overall length. Measure the distance between the center of the rear axle and the center of the crank bolt with a tape measure. In order to get the length of the chainstay, write down the length to the nearest eighth of an inch or 0.125 of an inch.

Method 2: Using a Ruler to Measure Choose a rivet and place it exactly where the zero mark is. The last rivet should be at the 12′′ mark on your ruler after you have counted 24 additional rivets. If it is off by more than 1/16′′, your chain has become stretched to the point where it has to be replaced.

How do I measure for a full suspension bike chain?

It is important to note that when riding a full suspension mountain bike, you must ensure that the length of chain required does not alter as the suspension is compressed. Measure the distance between the center of the crankshaft and the center of the rear axle for this purpose. Now, remove the air (or spring) from the rear shock and repeat the measuring process once again.

Are all bicycle chains the same size?

No, not all bicycle chains are of the same length and width. The number of sprockets, the speed of the bike, the distance between the front chainring and the rear gears, and the number of teeth on the cogs all influence the size. What is the difference between the various chain sizes?

How to mount a chain on a bike?

As an added bonus, using a bike stand will allow you to remove the rear wheel, making it much easier to attach a chain and standing upright, which is much less taxing on your back. Chains with a chain lock may be unlocked with a special set of pliers that are designed specifically for this purpose.

How do I know what size chain I need for my bike?

The method used for chain sizing is determined by the range of gears available in the system. For bicycles with rear sprockets with 36 teeth or fewer teeth, the standard method is to measure using the largest rear sprocket and the largest front ring as a point of comparison. Two rivets are placed to this (each one inch in length) to mark the location where the chain will be cut.

What size is single speed bicycle chain?

Most single-speed bicycles and bicycles with internal gearing use a 1/8′ (0.125′, 3.18 mm) chain, which is equivalent to 3.18 mm. Chain measuring 3/32′ (0.094′, 2.30 mm) in length is used on derailer-equipped bicycles with more than three gears in the rear wheel. Typically, even a somewhat narrower chain is used.

Are bike chains universal?

No. Not all bike chains, regardless of their brand or model, are compatible with all bicycles. Although the majority of current bike chains are designed with a half-inch pitch, this does not imply that all chains will fit all bicycles.

What size chain is bicycle chain?

Chains are available in four different roller widths: 332 in (2.4 mm), 18 in (3.2 mm), 532 in (4.0 mm), and 316 in (4.8 mm).Roller width is the internal width between the inner plates of the chain.18 in (3.2 mm) chains are commonly used on bicycles with a single rear sprocket, such as those with coaster brakes, hub gears, fixed gears, or track bicycles or BMX bicycles, among other applications.

How do you calculate chain links?


  1. Make a mental note of C, where C = CD/p
  2. Calculate A, where A = Z1 + Z2, and A = Z3.
  3. Calculate S, where S = Z2 – Z1 is the answer.
  4. Find the T value for the computed S value in the adjacent table by referring to the table.
  5. Length of the chain in pitches (CL) is equal to 2C + (A/2) + (T/C)
