# FAQ: How To Work Bicycle Chain?

## What number chain is on a bicycle?

Bicycle Chains are generally categorized into two types: 1/2 × 1/8 and 1/2 × 3/32. The first number (1/2) is the chain pitch; the latter numbers (1/8 and 3/32, respectively) indicate the inner width in inches.

## 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

## Does bicycle chain make a difference?

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.

## 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.

## How long do bicycle chains last?
