Okay so I got a slightly warped axle rod.or axle bolt.and one shop said it's not too bad but I want to try and fix it.
So I have a 27inch wheel with a Sun tour back hub with six gears and a warped bolt.
I found a back wheel in the trash of a bike shop .and it's a 700c with a shimano 7gear hub

What can I do here. Can I replace one hub for the other or something and gain another gear,?

Replacing a hub is a lot of work, but it can be done.

Does your old hub have a freewheel? The new one, is it a cassette or freewheel?

See the Sheldon Brown notes:
Freewheel or Cassette?

Also, are your shifters "friction" (just move them to the right spot), or indexed? If friction, upgrading a freewheel is usually fairly easy.

Is the old wheel bolt-on, or with Quick Release?

Hunt on E-Bay or Amazon for a replacement axle.

For solid axles, I've been able to get them reasonably straight by putting 2 nuts on them, then giving them a whack in the middle with a hammer on an anvil, then checking if straight (rolling on glass), and repeating.

Replace the bent axle. Any decent bike shop should have one in an appropriate configuration (hollow for a quick release or solid, proper length, correct threads for your existing cones).

You have a Free Wheel, which tends to bend axles pretty easy.
If you hit pot holes, driveway lips etc., you'll probably just bend the new one too.
IF the axle isn't too bad, just locate it the same way in the drop outs each time you remove the wheel.

The 7 speed wheel may be spaced wider than your drop outs. Sometimes you can just jam the wheel in, depending on how "flexy" your steel frame is.
OTOH, sometimes you'll get interference with the smallest cog/chain stay and need to add a bit of spacing to that end of the axle which makes it harder to jam in.

Also, your rear brake pads have to have the ability to be moved 4mm closer to the axle because of the slightly smaller (8mm) diameter of the 700C wheel.

So can I put a wheel on my bike with the current shifters that's does bend axles.the other one that isn't a free wheel

valleyof

So can I replace the wheel with another hub type that doesn't bend axles so easily.
Do they make 27 inch with a free hub and not a freewheel

They? Who do you Mean? NB: someone can build up a wheel with any combination of parts that are Available ..

like your local bike shop.

I built up a Freewheel hub wheel set and toured on those wheels for 10 years .. the similar hub alone Now,

is probably More than You are willing to Pay ..

Install the wheel with the bend of the axle pointing downward, then run over a pothole. Repeat as necessary.

They bent if you looked at them funny. And I was a 160 lb skinny teenager when I was riding freewheel type hubs.

The cassette freehub body is a huge improvement.

Honestly, just put it back in the trash can where you found it. It was there for a reason.

Wilfred Laurier

Remove the wheel, rotate axle so the bend is going upwards, hit the axle with a hammer to bend it back the other way, repeat using softer hammer blows until it is perfectly straight.

Also, new axle and cone sets are usually between $10 and $15.

Retro Grouch 

Sure. You can have one built up. All it takes is money.

The real question is: "Why do you have a bike with 27 inch wheels and a freewheel hub?" My bet is that you have budget issues. By far the least costly solution is to repair the hub that you have now and hope that it will last a few more years before bending again. Maybe by that time your budget will have expanded enough for you to be able to buy a newer bike.

Stuff is in the bike shop's trash because it belongs there. It's likely to cause you more trouble.

So they don't sale a different wheel with hub different. Did you guys even read my last post.stay on topic.don't go astray

valleyof

Yeah I'm talking about a free hub for a 27inch now.posing a questions did they exist, I read your post guys.
I'm not trying to repair a freewheel I want a free hub.stay on topic.when was money an issue on this problem I don't remember it.
I'm buying a new wheel if I can, 27inch free hub if they sale em. Again last shop said it wasn't tthat bad. They just said it's common for that wheel. I want a different wheel.

fietsbob

go back into the front of the bike shop and ask there, rather than stay on this hamster wheel .. of opinions.

Bill Kapaun

I've built a set, but one would be hard pressed to find a commercially available one.
It's a problem of supply & demand.

Most 27" wheeled bikes have narrower dropout spacing then available Free Hubs.
A wheel builder would have to narrow the hub spacing, and then pick a rim/spoke combination that would sell within a reasonable time.
That's simply not going to happen with a 27" rim.
