skewed rear hub

Hello again guys once more!

I have this wheel from an old bike but the freewheel seems skewed (the rear hub rather). Do you think there's a way to fix this? Or even ride with it without having problem?

Here's a picture

wheel needs to be dished. spokes are loosey goosey i bet. the wheel could also be a single speed wheel. where is the right side of the axle?

It would help greatly if you fully described the problem without using words that can mean a variety of things (skewed), learned enough from the sources listed in "New-Posters-please-READ-THIS," to use correct terms (it's a freewheel, not a cassette) and if you took enough care to edit your post to eliminate obvious errors ("read" hub?).

That being said I can only guess, but if you mean the freewheel seems to be on at an angle to the hub - that is certainly a problem. As there is no axle installed and it's an old steel wheel with some rust apparent at the spokes you need to throw the wheel away.

Sorry man but english is not my mother tongue and I just started to learn the bike parts in english (I'm going to look the New Posters thread). Although my description is not 100% accurate I think the picture shows everything you need to know about the problem (that's why I added it to the text). There is an axle, but I took it out to clean it.

It looks to me like the freewheel has been crossthreaded on. If it was my wheel I'd try to remove the freewheel and see how the hub threads look. I don't have good feelings about ever making a good wheel out of this.

I certainly understand the challenge of a 2nd language, having visited Italy 2 years ago, but read instead of rear is a typo easily fixed by a quick re-read and edit, and "skewed" tells us nothing, whereas "the freewheel looks crooked on the hub" would tell us that is the problem - and you still have not verified that is your concern.

Somehow you are missing more than words. You already removed the axle, but any decent tutorial on hub overhaul would advise removing the freewheel before beginning a hub overhaul, as most freewheel tools depend on the axle to center it and the nut or skewer to hold it firmly onto the freewheel notches. A cross threaded freewheel may not lend itself even to proper removal techniques.

As I mentioned, the spoke nipples appear to be rusted, which means you may be unable to true the wheel, the rim is steel, which means very poor wet braking (and some excess weight). Most likely the bearing surfaces are not in good shape, and parts will be hard to come by. Put that with a cross-threaded freewheel and it's trash time. Find a curb pick in better shape.

Show it to someone in a bike shop ... live.

Freewheels are fine, with wobbles, in their context,
friction shifting and full height teeth.
as the chain tends to stay put when the shift is completed.

It's the indexing that's fussy, and more cogs, in the same width,
the less tolerant it is.

Yes, have found same problem on a number of bikes. Wierd, huh? My guess is bike was jumped or stunt riden, hence, bent axle. ?

It's not a bent axle. Definitely looks like the freewheel is crossthreaded. You may be able to get it off and rethread it straight if the threads aren't totally damaged. But the wheel is probably not worth spending too much time on...

On cheaper bikes I've seen hubs that are obviously made from three pieces of steel pressings. It looks to me like this may be one of that style of hub and that the wheel was driven over or exposed to some other form of major pressure that has deformed the hub. Either that or the freewheel is simply cross threaded as mentioned. But to me it looks like the spoke head flange is out of whack as well. The flange appearing to be in line with the freewheel and clearly out of line with the middle portion of the hub.

The fact that the rim appears to be chromed steel is what further leads me to suspect it's one of the very cheaply made multi piece steel hubs as well. And if all this is the case then this wheel simply is not worth spending any amount of time on.

Guys, as far as his use of English goes he's doing a LOT better than some of the North American posters I've seen as far as both grammar, spelling and sentance structure goes. Yet you cut those posters a lot more slack and even jump on those that tell them to learn their native language better. By all means we should all try to learn to write properly and clearly. But if you're going to tar and feather anyone it should be the posters that are clearly english first language who can't even use ONE language properly.

Mighty Legnano, you may want to edit your user profile to include your home city or town. It would let folks know that you're from another country.

Good call - definitely suspicious!

You can probably get an entire used bike with a similar quality wheel for the same price as getting this fixed at a shop...

Not sure where you get "you cut those posters a lot more slack and even jump on those that tell them to learn their native language better." as I do neither. Actually I did not question grammar nor spelling, but rather lack of care in proofreading and lack of a clear description of the problem. I don't believe what I said approached the "tar and feather" level, either.

But in the spirit of what you requested, and assuming you are a native English speaker: "..as far as both grammar, spelling and sentance structure goes" should be "as far as grammar, spelling and sentence structure go.

cny-bikeman, don't worry, I'll be more specific in the future.

I will dish the wheel as you all agree that it doesn't worth the time.
But for the sake of it, I think BCRider got it right. And I'm beginning to suspect defective product because the spoke flange doesn't seem bent at all.
Other than that the wheel is not that bad. Just 2 broken spokes and minor rusting.

Here's a better picture.

+1,000, to use a highly technical term, the wheel is toast. The photo clearly shows the freewheel to be off axis to the hub. (skewed is appropriately here, supported by the photo)

Odds are the wheel isn't salvageable, though the freewheel itself might be.

Even if it could be saved the cost would be beyond that of a replacement.

Great pic - sometimes words are not enough. The view before made it look to me as if the freewheel was not aligned with the flange, but now I can see that the flange is not perpendicular to the hub tunnel. It is indeed a 3 piece hub and the flange has broken free.

I am not sure about this. Freewheels can certainly be cross-threaded, but from what I see in the pics the freewheel cogs look fairly parallel to the driveside hub flange. The freewheel cogs do look out of allignment with the wheel rim, which would lead me to surmise that the wheel is not properly dished, as noted by reptilezs.

Dish has nothing to do with it. Seems like 1/2 the responses in the mechanic thread are people picking terms at random and suggesting that's the answer.

Dish is the relationship between the rim and the locknuts. A properly dished wheel has a rim that is centered between the locknuts. An improperly dished wheel has a rim a bit to the left or right of center, although it may still be perfectly true. However, it will be off center relative to the frame.

In this case, we are seeing things that appear to be out of alignment (not parallel) caused by cross threading, hub threads off center to hub axis, broken/bent hub flange or such.

Did anyone notice the right hub flange is bent badly, given the fact that the hubs as inexpesnive three piece types and very unlikly to be fixed consider something else

OP. if you grab the freewheel, does it wiggle at all ? If so, do you see part of the hub moving with it ?
The failing hub flange seems likely.

It's hard to tell from the OP's last post, but I believe he has decided to ditch (not dish) the wheel. It's not a matter of debate after the last pic. As I already pointed out, the hub flange is not just out of parallel with the rim - it is not perpendicular to the hub tunnel. The hub is broken, cannot be fixed, end of story.
