Rear wheel dilema

Hey, I'm not sure what to do. I need my bike to be in reliable condition

So I just bought the following from performancebike:

Shimano Ultegra 9 speed / Mavic Open Pro Silver Road Wheel - Rear
Shimano® Ultegra® HG 9-speed Cassette
Shimano HG-91 7/8 speed chain (replaced about a month ago when it broke).

the chain is way too big. Here's a pic

The other potential problem is the 9 speed is wider than the frame,

So you bought a 9-speed wheel when your bike used something else? When
you switch to a different number of speeds, usually you have to change
more than just the wheel. Do you use indexed shifters? If so, you'll
have to get 9-speed ones. And 9-speed cassettes do require 9-speed
chains.

Quoted message said:

Do they make 8 speed freehubs that would go on a 9 speed wheel? Isn't
the hub the same on a 8 speed and 9 speed wheel? If so why is the one I
bought called 9 speed?

The freehub body is the same for 8 and 9 speed cassettes. It is their
sprocket thicknesses and spacings that differ. If you had 8-speed
before, and if you haven' t tried to ride with your new cassette, you
should clean the 9-speed cassette and return it for an 8-speed one.

Thanks.. I haven't put the cassette on the wheel yet so I should be able
to return it.

Michael Shaffer said:

So, what should I do? I guess the easiest thing would be to get a 9
speed chain but would it work with the front chainrings?

Yes.

You mean that the new wheel does not fit in between the
drop outs? If the frame is steel you can spread the rear
drop outs and realign the drop outs. Otherwise

Ask before you buy?

No. Not without bodging, and you are not ready.

Where did you buy the stuff? A local store? Then you can

OOps, I meant 8 speed cassettes. I was reading on Sheldon Brown's
website and it looks like I can just get a 8 speed cassette. I think
I'll do that instead of changing the chain, so I can still use my old
wheel if I want to.

The hub is the same if it's got a Shimano compatible steel freehub
body. Only the cassette is different.

I forgot to mention one more thing-- it sounds like you got a 135mm
wide wheel to replace a 130mm wide wheel. If your bike is steel, it
can be bent slightly open to match the wider hub. You should seek help
from a bike shop for this.

If your bike has an aluminum frame, the easiest thing is probably just
to spread the frame a bit when you insert the wheel. It's a little bit
annoying, but the reward is a significantly stronger wheel.

I see, the bike is a Cannondale Criterium, so it should be easy to bend..

Do not, do NOT *bend* an aluminum frame. You can *maybe* flex it a
little, but I'd avoid that as much as possible. Aluminum doesn't
handle bending very well, and the result may well be the destruction of
your frame in the short term. Steel flexes, and so it's easy to spread
a frame a few mm (or compress it) to fit a wheel with different
dimensions.

What you need to do: Either (1) take your original wheel to an LBS and
get it fixed (cheap) or (2)buy a new wheel with the correct spacing,
and transfer your existing cassette to it (moderate). Using the
original cassette means that you will also be able to use your existing
chain (cassettes and chains can wear together, making mix-matching
difficult, in principle). Alternatively, (3)new wheel, new cassette,
and new chain (costly) but that will only work if (a) your shifters are
friction-type/have a friction mode (8s shifters won't shift a 9s
cassette properly) or (b)you're willing to replace them (EXPENSIVE!).
So, from a cost perspective, cheapest to most expensive, your options
are: 1,2,3a,3b. I'd take a stab at them in order...

Go to a decent bike shop with all the stuff you bought and your bicycle
and let them explian the differences between 8s, 9s, 7s, rear triangle
differences, shifter differences, etc. First hand.

Ultegra 9s rear hub. I guessing his frame may be 126mm...since he
mentioned the axle of the old wheel was bent=frewheel, probably a 6/7s
one..126mm...

This is the wheel

It says 130mm

Ok, lets get the language nitpicking out of the way first. This is a

You should always replace the chain when you install a new cassette in
any case, so this is not a real problem. Running a used chain on a new
cassette leads to rapid wear of the casssette, and frequently causes
jumping/skipping under load.

Ultegra hubs are the same 130 mm spacing as all "road" hubs made in the
last 15 years, 8-/9-/10-speed.

(In the Shimano world there's no difference among these. Your Ultegra
hub will work with any Shimano Hypgerglide cassette, any number of
speeds. If for some bizarre reason you wanted to use a 7-speed cassette
that would work too, but you would need one extra spacer.)

There's no difference between an "8-speed" and "9-speed" Freehub.

Right.

It's about marketing, not any functional difference.

I've got a 130mm wheel in a 126mm Cannondale. It flexes enough to get it in
there without excessive grief.

Definitely don't try to cold-set it, though.

I just put the wheel on for the first time and it went in pretty easily.
I tried taking it off too and that was just as easy as the 126mm wheel.
I don't think a 135mm would fit but 130mm is fine.

Well, that works out then, but it leaves the issue of your rear
shifter. From what you said earlier, I thought you were starting with
an 8 speed bike. Since you are going from 6 to 9 speeds, you have the
choice of finding a 9s downtube shift lever (uncommon), updating your
bike to brake-lever-mounted shifters ($$$), or else just using the
friction mode on what you've got. Friction shifting 9 sprockets
requires a lot more precision than shifting 6.

This is all a lot more expensive and complicated than just getting a 6
speed wheel for a 6 speed bike.
