How do I know if my cassette is freewheel?

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.

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 often should a bike cassette be replaced?

My rule of thumb is to replace it at 75 per cent wear (as measured with a chain-wear indicator). If you stick with this guideline, your cassette and chainrings will last a lot longer. A cassette, in most cases, can last for approximately two to three chain replacements if they are done at the right time.

How many miles should a bike cassette last?

1000 milesGet at least a 1000 miles out of chain and cassette. Always change both at same time.

Are 7 and 8 speed cassettes interchangeable?

A 7 and 8 speed cassette have the same amount of space between each cog. An 8 speed cassette is slightly wider than a 7 speed cassette because of that added gear. … Simply put – 8, 9, 10 speed cassettes all fit on the same hub. A seven speed cassette will fit on an 8 speed freehub with the use of a spacer.

How much does it cost to replace a bike cassette?

The cost to replace a cassette or freewheel can range anywhere from $25 to upwards of $300 on high end bikes and chainrings can run anywhere from around $40 to $250 on high end bikes.

What is the difference between a freewheel and cassette hub?

What is the main difference between freewheel and cassette hub? The freewheel is a single-unit and the act of pedaling tightens the freewheel to the hub. Whereas the cassette hub is a set of gears (cogs) that slides onto a cassette and is held in place by a lock ring.

How do I know what size my bike cassette is?

Sprockets vary in size according to the number of teeth they have. A cassette may therefore be sized as 11-32t. The first number refers to the number of teeth on the smallest sprocket (the highest gear, for fast pedalling at speed) and the second number to the biggest sprocket (the lowest gear, for climbing hills).

Can I replace a freewheel with a cassette?

1 Answer. No, it is not possible. You need to replace the entire hub, and the easiest way to do that is to replace the entire wheel.

Does a 9 speed cassette need a spacer?

If you have a 9-speed cassette, you only use the 1.85mm spacer. If you have a Shimano 10 cassette, you use the 1.85 PLUS the 1mm 10-speed spacer. … If you want to use 11-speed Shimano components with a Mavic wheel, simply use no spacers at all.

How do I know what kind of cassette I have?

The 4 notches found at the top of a metal cassette are the easiest way to identify the tape type. The notches on the outside of the tape tell the cassette deck to use the bias of a Type II tape. The notches on the inside of the cassette tell the player to push the bias even further!

What is a 12/25 cassette?

The 12-25 is 12-13-14-15-16-17-19-21-23-25. The 12-27 is 12-13-14-15-16-17-19-21-24-27. Only the last two cogs are different between the 12-25 and 12-27. You get lower, more useful cogs with the 12-27 over the 12-25.
