Often asked: How Do You Know What Size Bike Cassette I Have?

How can I tell what cassette I have on 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.

Do all cassettes fit all bikes?

SRAM and Shimano cassettes, on either road or mountain bike, are interchangeable with each other as the spacing is the same between the sprockets. However, Campagnolo road cassettes will only work with Campagnolo drivetrains.

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.

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.

How long does a bike cassette last?

A cassette, in most cases, can last for approximately two to three chain replacements if they are done at the right time.

Can you change cassette size?

Do You Need A Longer Chain For A Bigger Cassette? In most cases when increasing the cassette ratio the chain needs to be taller to prevent the derailleur from stress positions on big cogs and also to maintain smoother shifting performance, you can change it to a new one or add some links to the current chain.

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.

How often should you replace your cassette?

As mentioned, you will want to replace your bike cassette at least once every three years, even if you are not riding super regularly. However, if you are riding your bike a high mileage each year, you will want to change the cassette each season.

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 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.

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.

Should I replace chain and cassette together?

You should change your chain at the same time as the cassette and/or chainset. “A worn chain on a new cassette or chainrings will only accelerate the wear,” says Chris McKenney.

What is the cassette on a bike?

The cassette on your bicycle can be found on the rear wheel and is a cluster of sprockets that are a part of the drivetrain. They slide onto the freehub, the ratchet system that controls the drive of your bicycle when you pedal, and can have anything from 5 to 12 ‘speeds’.

How often should you change your bike chain and cassette?

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.
