Question: How To Measure Bicycle Chain Stretch?

How do you measure a bike chain?

Begin by counting the number of teeth on the largest front sprocket and largest rear. These numbers are often printed right on the sprockets and cogs. Next, measure the distance between the middle of the crank bolt to the rear axle. This is also the chain stay length.

How much can a chain stretch?

The maximum allowable wear elongation is approximately 3% for most industrial applications, based upon sprocket design. The allowable chain wear in percent for large sprockets with 68 teeth or greater can be calculated using the relationship: 200/N, where N is the number of teeth in the large sprocket.

How often should I change my bike chain?

The 2,000-Mile Rule. 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. 4

What size is standard bicycle chain?

Chains come in 3⁄32 in (2.4 mm), 1⁄8 in (3.2 mm), 5⁄32 in (4.0 mm), or 3⁄16 in (4.8 mm) roller widths, the internal width between the inner plates. 1⁄8 in (3.2 mm) chains are typically used on bikes with a single rear sprocket: those with coaster brakes, hub gears, fixed gears such as track bicycles, or BMX bikes.

What is the difference between bicycle chains?

Chains can vary in side plate shape, sizing, and height. Differences can cause variations in shifting performance between brands and models. Additionally, chains will vary in the quality of steel used. Better chains that are more durable and longer lasting tend to have harder rivets.

How often should I lube my bike chain?

Bicycle Tutor recommends cleaning and lubricating your bike’s drive chain at least once every month to maintain optimal performance and protection. The chain and drivetrain are typically the dirtiest parts of your bike, and this dirt is bad news for bike longevity and performance.

What is the first step to start riding a bicycle?

TEACH CYCLING TO YOUR CHILD IN 10 STEPS

  1. Gear up. That means a properly fitting helmet, kneepads, and elbow pads to protect your child from all of those “almosts.”
  2. Make the seat height just right.
  3. You hold, they pedal.
  4. Slowly take your hand away.
  5. Repeat!
  6. Take a break.
  7. Raise the seat.
  8. Master the ups and downs.

Can a chain stretch?

Although chains are frequently described as having stretched due to wear and use, the term “chain stretch” is slightly misleading. The phenomenon of chain stretch is more properly referred to as chain elongation, since it is not the case that the chain links themselves are actually getting longer.

What causes chain to stretch?

Chain wear is commonly referred to as ‘chain stretch’, because the chain’s pitch grows in length as it wears. This is the most important type of chain wear, and the growth comes from the bushings wearing with the chain pins. Overtime, the inner diameter of these bushings increase and the pins groove out.

HOW TO MEASURE CHAIN WEAR

  1. Pull the chain slightly until it is taut.
  2. Use a vernier caliper to measure the distance of the inside (L1) and the outside (L2) of the rollers at both ends of the measured links.
  3. The average of (L1) and (L2) gives you the measured length (L).
