## How do I know my bike chain size?

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.

## 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 do I know if my bike is 10 or 11 speed?

Multiply the front gear number by the rear gear number to get the number of speeds. For example, if you have two front gears and five back gears, you have a 10-speed bike.

## Are 7 and 8 speed chains the same?

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. That is why the reverse is not the case and a 7 speed chain and especially a 6 speed one will not work as well on an 8 speed system.

## What is chain stay?

the chain stay is the part of the frame thats nearest to your chain, and often gets big gashes in it from your chain hitting it. often people have something covering there chainstay to protect it from the chain hitting it.

## 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 is the most common bike chain size?

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 all bicycle chains the same size?

Are all bicycle chains the same size? No, all bicycle chains are not the same size. Size varies on the bike’s numbers of sprockets, speeds, the distance between the front chainring and rear cogs, and the number of teeth on them.

## Which gear is 1 on a bike?

Downshifting, or decreasing the resistance, allows for faster and easier pedaling; upshifting, or increasing the resistance requires more effort and builds endurance. On your shift lever, the lowest number, No. 1, represents first gear.

## Is gear 1 high or low on a bike?

Bikes generally have 1, 3, 18, 21, 24, or 27 speeds. (10- and 15-speeds are obsolete and you don’t see them on new bikes anymore.) Lower numbers are the low gears, and higher numbers are the high gears. First gear is a low gear.

## What does 10 speed mean on a bike?

A 10-speed bike is a type of road bicycle that allows you to change the pedaling resistance through a shifting mechanism. The various gears provide up to 10 different resistance settings, or speeds. This type of bicycle engineering makes riding on hilly terrain over long distances easier.

## Will a 9 speed chain fit 8 speed?

9 speed chain on an 8 speed cassette is just fine; it’s the wider 8 speed which won’t fit the sprocket spacing on a 9 speed cassette.

## Can I replace a 7 speed freewheel with an 8 speed?

You can change to 8 speed, but a normal rear wheel for roadbikes will not fit directly into the frame because it’s 130 mm wide. Depends on the stiffness of the rear frame if it can be pushed together safely to 130 mm.

## Can I use a 9 speed derailleur on a 8 speed?

8 and 9-speed derailleurs have the same rear shift ratio but only when both models are made either by Shimano or SRAM. In consequence, a 9-speed derailleur can work just fine with an 8-speed cassette produced by the same brand. If the bicycle uses index shifting, the shifter will have to be designed for 8 speeds too.
