# Quick Answer: How To Choose The Correct Size Of Cassette For Your Bike?

## How do I know what cassette fits my bike?

To determine if a sprocket is a freewheel or cassette system, remove the rear wheel from the bike. Find the tool fitting on the sprocket set. Spin the sprockets backwards. If the fittings spin with the cogs, it is a cassette system with a freehub.

## What does an 11-32 cassette mean on a bike?

The rear cassette is 11 speed 11-32. This means there are 11 cogs ranging from 11 teeth up to 32 teeth (the exact cogs are 11/12/13/14/16/18/20/22/25/28/32). The combination of your selected chainring and cog determine the gear ratio.

## What is the difference between 11-28 and 11-32 cassette?

For the 11-32 cassette, the average change in cadence is 9 rpm when you change gears, while for the 11-28 cassette, the average change is 8 rpm. In concept this difference is intuitive, although the magnitude on average is not that different between the cassettes – just 1 rpm.

## What is an 11-28 cassette?

Currently, the most common gearing setup on new road bikes is a 50/34 chainset with an 11-28 cassette. This means that the big and small chainring have 50 and 34 teeth, respectively, and the cassette’s smallest cog has 11 teeth and its largest cog has 28 teeth.

## Are all bike cassettes the same size?

Most road bike cassettes have an 11, 12, or 13-tooth smallest sprocket, then between 21 and 32 teeth on the largest sprocket. The vast majority of road bikes come with a 12-25 cassette, which is suitable for most cycling terrain when paired with a compact or standard chainset.

## How much does it cost to replace a bike cassette?

It cost anything between \$20 and \$150 to replace a bike cassette, depending on size and brand. There are a few high-end cassettes, nonetheless, that cost as much as \$300 or more. Note that you’ll need to factor in the labor cost and the chain cost (if it’s worn out), each averaging \$20.

## 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 size cassette do pros use?

Pros often use a 55×11-tooth high gear for time trials. On flat or rolling stages they might have 53/39T chainrings with an 11-21T cassette. In moderate mountains they switch to a large cog of 23T or 25T. These days, they’ve joined the big-gear revolution like many recreational riders.

## What bike gear do you use to go uphill?

When riding uphill or into a headwind, it’s best to use the small or middle front chainring and bigger rear cogs. When riding downhill, it’s best to use the bigger front chainring and a range of the smaller rear cogs.

## Is 11/32 cassette Good for hills?

Most riders can get away with a compact chainset 50 / 34 and an 11 – 32 cassette for their steepest hills. Many touring bikes and tandems still use triple chainsets, but they often have heavier loads to haul.

## Do all cassettes fit all hubs?

Most cassette hubs are compatible with Shimano cassette cogs. SRAM cassettes and most Miche, IRD and SunRace cassettes use the same inter-sprocket spacing as Shimano, but at least some SRAM 10-speed cassettes do not fit aluminum-body Dura-Ace hubs.

## What is a 52 36 crankset?

A semi-compact chainset, sometimes called mid-compact or faux pro, has a 52-tooth outer chainring and a 36-tooth inner chainring. This means that the biggest gears aren’t quite as big as those of a 53/39 chainset but they’re not far off, and they’re larger than those of a compact.

## What gear ratio is best for climbing?

If the rider wants to maintain a more comfortable cadence of 60 rpm on such a climb then the chainrings, cassette or both should be changed to have a lowest ratio of no more than 0.92:1.
