Bicycles How Long Should A Cycle Hub Freewheel Last

Question

Answer

Do bicycle hubs wear out?

If there’s any sign of wear on them, they’ll need replacing. Note: The cups in Shimano, and many other clone hubs, are non-replaceable. If they have worn out, you will have to rebuild a new hub into your wheel.

When should I replace my free hub?

The small ball bearings are available as replacement parts. However, if the bearings are worn out and require replacing, it is very likely the entire freehub is needing replacement.

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 long should a freehub last?

If it wears out completely you end up pedalling fast and going nowhere. Mine seem to last about 5,000 to 10,000 miles and the usual signs of wear are noises and play. Price depends on quality, but they’re not bank-breakers.

When should I replace my bike hub?

If there are any spots of real resistance or bumps, the bearing has likely pitted (eaten into) the bearing race. If this is the case then a replacement is needed. Likewise, if you can move the inner race laterally (in and out of the hub) then the bearing probably requires replacing.

How do I know if my bike hub is bad?

If you find that the wheel turns stiffly when you move it lightly by hand, or even seems notchy or wants to stop on its own, it’s a sign that the hub has issues and needs maintenance.

Should I grease freehub?

There’s no reason to grease the freehub body. Some mechanics, who have been working on bikes for decades, find that greasing all metal-to-metal surfaces is a generally good practice. In the case of the freehub body, grease may serve to reduce noises.

How many bearings does a Shimano freewheel have?

Typically you’ll have 10 bearings per side in the front and nine bearings per side in the back.

Why is a cassette better than a freewheel?

A cassette is the more modern option and has quickly overtaken the freewheel. Cassettes as they have a series of straight splines that form the mechanical connection between the sprockets and the cassette compatible hub, which is called a freehub, and contains the ratcheting mechanism.

Can you put a cassette on a freewheel hub?

Cassette hubs cannot accept freewheels; nor can freewheel hubs accept a cassette. The freehub body of a cassette hub is shaped specifically for a cassette. Meanwhile, freewheels and freewheel hubs operate with a threaded system. Thus, it’s impossible to mount a freewheel on a cassette hub.
