How Do I Know My Bike Chain Size?

How do I know my bike chain size?

  • Count the number of teeth on the biggest front sprocket and largest rear sprocket.
  • Next, you need to measure the distance between the crank bolt's rear axle and midpoint.
  • Are 6 7 8 speed chains the same?

    5, 6, 7 and 8 speed chains

    Shimano, SRAM and Campagnolo all use the same chain with 8 speeds. Chain for 7 speeds is a bit wider – 7.3 mm, while a 6 speed one is substantially wider – 7.8 mm. Going further narrower, like a 10, or 11 speed chain on an 8 speed cassette can and often does work.

    What is a 3/32 bike chain?

    3/32" (0.094", 2.30 mm) chain is used on derailer equipped bicycles that have more than 3 cogs at the rear. Even somewhat narrower chain, typically . 090" or 2.29 mm between the inner plates, is used for derailer-equipped bicycles with 9 or more sprockets at the rear.

    What Is a Number 35 chain?

    #35 Chain: Typically seen on small wheeled mini-bikes and dead axle karts. This smaller chain is lightweight and comes with more racing options than it's bigger counterparts. We stock a variation of clutches and sprockets to fit this chain.

    How do you size a chain?

    Are all bicycle chains the same pitch?

    All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches. The sprocket teeth are cut for this same one-half inch standard to accept bicycle chains.

    Are 10 and 11 speed chains the same?

    Chains for 11-speed systems are around 5.4mm wide on the outside, vs. around 5.9mm wide for 10-speed ones, so that's 0.25mm narrower from the center of the cog tooth to the end of the chain pin on each side. That's not enough to likely even be noticeable in any difference in how it passes through the jockey wheel cage.

    Do SRAM chains work with Shimano?

    Shimano and SRAM 11-speed chains are cross-compatible. If you have a Shimano 11-speed drivetrain, a SRAM chain will work fine and vice versa, however manufacturer's recommend pairing your components for optimal performance.

    Is Shimano or SRAM better?

    The main differences between SRAM vs Shimano are: SRAM has a stronger hold over the high end of the groupset market, whereas Shimano's groupsets are often bought by entry to mid-level users. Shimano shifting actuation works on a 1:1 ratio, whereas SRAM's shifting actuation works on a 2:1 ratio.

    What is the difference between #35 and #40 chain?

    The main difference between the 35 and the 40 chain is that one is rollerless and the other has rollers. The two chains also have different pitches and diameters, which will limit their interoperability. Additionally, the 40 chain is rated for a significantly higher tensile strength and working load than the 35.

    What does a 420 chain mean?

    For example, a 420 chain has a pitch of 4/8" = 1/2" (12.70mm) and a roller width of 2.0/8" = 1/4" (6.35mm).

    How strong is #35 chain?

    #35 Chain That Meets Rigorous Quality Standards

    Part No. 35R
    Overall Width (G) 0.303
    Unit of Measure (Inches or Millimeters) in
    Average Tensile Strength (Lbs.) 2,469
    Average Weight Per Foot (Lbs./Ft.) 0.215

    Do I need wide or single speed chain narrow?

    Essentially, no purpose is served by using a wide-narrow chain ring on SS. But if it's all you can find, you may have to run with it. As previously mentioned, you won't be able to do anything with a chain that requires a half link, but that's life. If you have to have a 30 tooth, you have to have it.

    How do you replace a bicycle chain?

  • Remove the old chain. First, jettison the old chain.
  • Clean the cassette. Now is a good time to clean and inspect your chainrings and cassette.
  • Thread the new chain.
  • Work out the correct length.
  • Cut to size.
  • Insert the pin.
  • Push the pin home.
  • All done.

  • How many miles should a bike chain last?

    Most mechanics agree that you should replace your chain about every 2,000 to 3,000 miles, depending on your riding style. Many Tour De France riders wear out two or even three chains on their primary bike over the course of the three-week race.

    Which bike chain is best?

    The best bike chains: Best 10-speed chains

  • Sram PC1051.
  • Wippermann Connex 10S0.
  • Best money-no-object: KMC X11SL DLC.
  • Best all-round: Shimano 5800 105 11spd.
  • Best for Campy users: Campagnolo Potenza 11spd.
  • Best all-round: Sram Force 12spd.

  • How often should you change your bike chain?

    To avoid this accelerated wear of your cassette and chainrings, a general rule of thumb is to replace your bike's chain every 2,000 miles. Mind you, this is just a starting point. No two chains will wear at exactly the same rate because no two riders treat their chains the same.
