more questions!

first off I am converting an old bianchi brava and I was wondering if i replaced the rear wheel will I have to replace the front wheel as well?

Where is the best place to get a 700CC hub? (online) I want a wheel that is decent quality but price is also a concern

Why on earth would replacing the rear wheel make you need to replace the front?

search function answers!

No, you dont have to replace a front wheel if you replace the rear, unless you have issues with the cosmetic difference if your front wheel is a 27"
That said, you can probably find a wheelset for about what you will end up paying building a wheel, especially if you have someone else lace it.
If you are looking for a decent hub, look no further than a formula (or rebranded one) with sealed bearings, I would look into bens cycle, they have loads of track stuff.
It might be worth your time to look up bicycle wheels .com and check their selection of wheels, as they are very nicely priced.

The front wheel doesn't care what kind of drive train the bike has. So no, you don't have to replace the front wheel.

As to your second question, it's a bit confusing. Are you interested in buying an entire wheel, or just the hub? (The hub itself isn't specific to the size of the wheel, only the number of spoke holes and width of the axle.)

be nice to the noob guys.

EMJ:

Yes you can keep your front wheel.

700c is a rim size, not a hub size.

For reasons that make no sense "700c" actually refers to rims that are 622 mm in diameter. I don't think the "c" stands for "centimeters" or anything like that, it's more wacky and arbitrary than that.

Get a 700c fixed rear wheel for cheap at bicyclewheels.com and have fun learning more as you build up your conversion.

the tire says 700c and i need an entire wheel.

I thought "C" was a width category.

lols

No, as you Have 700C wheels you do not have to replace the front. but i would if i was you, bicyclewheelsdotcom have fixed wheelsets for 140$(personally i would go with the Wienman DP-18 36H's). Thats less than you will pay for a single rear wheel at the LBS.

Nope you can get 700c in lots of widths, at least from 19mm to somewhere around 30. All that stuff has to do with something that may have seemed like a good idea at the time but actually makes no sense, and now it's wrapped up in a giant cluster**** with lots of other things that seemed like a good idea at the time. For example, they call 700c "28 inch" in Germany even though it's "29 inch" when it goes on a mountain bike in North America; and even though 622 mm is just under 24 1/2 inches . Edit: and even though "27"" rims are bigger than 700c by around 8mm.

^^^ 13 mm to 30mm is typical see link - near the bottom of the page

edit: okay, now see the link

Holy moly that's skinny, I did not know that.

Edit: Hang, on that 13 is interior width. My 24mm wide trekking rims are 18mm wide on the inside. 13+6 is around 19.

the front is a 700 by 23 its like 128betwen the dropouts from inside to inside so i am guessing i need a 130mm hub?

My friend do not be afraid to take your bike into a shop. They will at the very least be able to tell you what size hub you would need. You won't need to replace your front wheel, but you can if you want (i.e. an upgrade either for aesthetic or performance reasons or both for people that find speed sexy). Oh and they're not referred to as 700cc hubs, but what you are looking for is a "road" hub. They are mostly found attached to 700cc wheels so i can see the confusion there. Anyhow if you would like to know a lot more interesting stuff about wheels you should check this out. Sheldon Brown will always be the man.

700c, not 700cc. Lets not make things any more confusing than they already are.

Yes OP, assuming you measured accurately, you want a 700c fixed rear wheel, with a hub that is spaced 130mm. You can make most 120mm spaced hubs 130 by adding washers under the locknuts (note: you probably don't know what a locknut is yet). But keep it simple and get one that's already set up 130.

I kknow the difference between a hub and a rim and a wheel
I know what a lock nut is. I cannnot however find a fixed wheel or set that is 130

the great gazoogle can find you one!

i ahve been shopping around. I just cant find a rim I know is decent and a price i wanna pay im looking for an inexpensive first fixed wheel for an old road bike conversion. so if you could suggest a budget shop or a budget wheel I would really appreciate it

whats your definition of "inexpensive"?

give me 700CC's of hub, stat!

Check with your LBS, mine sold me a set of wheels with Alex DA-22 rims, a SUrly front hub, and a SUrly flip/flop rear hub for $125. They were take offs, from a bike they'd sold, that the new owner upgraded at the time of purchase.

Read what Sheldon Brown said about tire sizes: https://www.sheldonbrown.com/tire-sizing.html

if the weel description says 120, adjustable how much can it be adjusted? can i make it fit a 130?

Is it a formula hub? I believe they all can be spaced out to 130. But really, why not call or email the person who is going to sell you this hub. They will know.
