KMC K-chains are a popular choice for parents looking to upgrade or replace chains on their kids' bikes.

Specifications and maintenance of kmc chain kits

KMC chains are available in various specifications to accommodate different riding styles, preferences, and bike types. Below are some common specifications:

  • Speed:

    The term speed refers to the number of sprockets on the cassette or freewheel. For instance, a chain with an 8-speed KMC chain kit has eight inner links. The 11-speed chains are ideal for high-performance bikes.

  • Gauge:

    The measurement of the chain is the width between the outer plates. The 1/8"" measurement is common in single-speed chains. The 3/32"" measurement is found in most KMC chain kits.

  • Material:

    The KMC chains are made from stainless steel and high-carbon steel. The latter has high tensile strength, making it ideal for heavy-duty applications. The stainless steel chains are rust and corrosion resistant.

  • Coating:

    The KMC chains have anti-rust and wear coatings. The coating enhances the chain durability and provides a smooth and quiet ride. The popular coating on these chains is the titanium nitride, nx, and eco black coatings.

  • Length:

    The chain length is measured in inches. A longer chain is suitable for bikes with larger frames. The KMC chain lengths range between 114 to 120 links. The 116 links chain is the most common among KMC chains.

  • Tensile strength:

    The KMC chains are designed to withstand various loads and stresses, depending on the bike type and riding style. The tensile strength is expressed in Newtons or pounds. Most KMC chains have a tensile strength of 1000-1500N.

  • Pin Power:

    The KMC chains have a pin power suitable for high-performance bikes. The pin power ensures a tight and secure fit of the chain on the sprockets. The pin power ranges from 60-90 lbs.

KMC chains are easy to maintain. Proper maintenance of the chains increases their lifespan and improves bike performance. Below are some of the KMC chain maintenance tips.

  • Cleaning: For effective performance, the KMC chains should be cleaned regularly. Wipe the chains with a clean and dry cloth after every ride. The chains should be cleaned thoroughly at least once a month. Use a chain cleaning tool or a brush to remove dirt, mud, and dust from the links. After cleaning, dry the chains completely to prevent rusting.
  • Lubrication: The KMC chains should be lubricated after every cleaning. The lube reduces friction, making shifting smoother and enhancing the bike's overall performance. When choosing the lube, go for the one with KMC's recommendations. Avoid over-lubricating the chains as this attracts dirt and dust.
  • Inspecting: Regularly check the KMC chains for signs of wear. Look out for loose links, rust, and dirt accumulation. A damaged chain can cause serious injury, especially when riding at high speed. Replace the chain if it is worn out.
  • Fitting: Always follow the manufacturer's fitting instructions when fitting a new KMC chain. Using the wrong fitting method leads to chain failure and can cause an accident. If the chain is difficult to install, consult a professional bike mechanic.
  • Storing: If the KMC chains are not in use, store them in a cool and dry place. The chains should be protected from extreme temperatures and direct sunlight. Avoid storing the chains in humid places, as this increases the risk of rusting.

How to choose KMC chain kit

Choosing the right KMC chain kit for a business is important, as it determines the sustainability of the business. When choosing a KMC chain kit, consider the following:

  • Know the bike or moto specs

    This includes knowing the speed and the model of the bike. This helps in knowing the right chain kit to buy, as the chain kits come in different speeds and matching the wrong chain with the bike will cause malfunctions.

  • Chain length

    The chain kit should be long enough to fit the bike without causing tension or slack. A chain that is too long or short causes wear and tear to the sprockets and the chain, reducing their lifespan.

  • Quality

    The KMC chain kit is known for its quality, but there are other quality brands on the market. Look for a chain kit with quality material, such as heat-treated steel, to give it strength and durability.

  • Riding conditions

    Consider the type of terrain and the weather conditions when choosing a chain kit. For a mountain chain kit, the chain is sealed to prevent mud from entering it. The sealed chain kits are good for mountain bikes because they reduce friction.

  • Budget

    Set aside a budget for the chain kit. The KMC chain kit is affordable, but there are other brands with competitive pricing. Remember, quality comes with a price, so avoid cheap chain kits because they will cost more in the long run.

  • Style and color

    The KMC chain kits come with a variety of colors. Choose the chain kit that will match the bike. The chain kits also come in a variety of styles, such as the gold chains and the black chains.

How to DIY and Replace KMC Chain Kit

Replacing the KMC chain kit on one's own is achievable with the right tools, chain knowledge, and a new replacement chain kit. Basic mechanical skills are also necessary. Here are the steps to follow:

Tools needed:

  • Chain Tool or KMC Missing Link Tool
  • Torx or Hex Wrench (for some models)
  • Phillips or Flathead Screwdriver
  • Shift Pliers
  • 9-speed chain checker
  • Chain cleaning tool
  • Lubricant
  • Shop towel
  • New KMC chain kit

Step-by-step guide

  • 1. Preparation

    Ensure that the bike is stable and secure. Shift the bike into the smallest chain ring and the smallest cassette cog. This makes the chain loose and easy to work on. Disconnect the derailleur from the chain.

  • 2. Remove the Old Chain

    Use a chain tool or KMC Missing Link Tool to disconnect the chain. Remove the chain completely from the bike.

  • 3. Remove the Old KMC Chain Rings and Cassettes

    Use a Torx or Hex wrench to remove the chain rings, if applicable. Remove the cassette from the free hub body. This is done using a cassette lock ring tool and a wrench.

  • 4. Install the New KMC Chain Kit

    Follow the instructions provided by the manufacturer. This includes installing the new chain rings, cassette, and guide pulley. Reconnect the derailleur.

  • 5. Install the New KMC Chain

    Refer to the installation instructions provided by KMC. Make sure to thread the chain in the proper direction through the derailleur and around the chain rings and cassette. Use the KMC Missing Link Tool or chain tool to connect the chain. Ensure that the connection is secure and smooth.

  • 6. Final Adjustments

    Check the chain tension and make any necessary adjustments using the derailleur's tension screw. Ensure that the shifting is smooth and precise through all gears. Lubricate the new chain and wipe off any excess lubricant. Clean the area around the chain and drivetrain components.
