I have an old motobecane that i am restoring. I want to put new mavic 700s on it but i do not want to go to the expense of changing shifters and derailleur.
Does anyone make a freewheel hub that i can lace onto this new rim?

You can find a freewheel hub pretty cheap, and lace a Mavic rim to it.

count the spokes and get a used hub with the same number.
You may need spokes and nipples, too. And a rim strip.

Is there any reason why you cannot use the original hub and simply lace it to the preferred rims?
If you must have a new hub, you should ensure that it is the correct width to fit between the rear drops. The two most common widths will be 120mm and 125mm...

You must also ensure that your present freewheel will fit the threading of the new hub. For example, you don't want to try to thread an English freewheel onto a French hub, or visa-virsa.
Also, what size wheels are on the bicycle at the moment - 700c or 27"? If 27", you might run into brake reach issues, with your present calipers having insufficient reach to meet the braking surfaces of then new rims. If that is the case, you will need to find a set of longer reach calipers.
Hope this is a help.

I am wondering, OH where are my manners HELLO Roboleg welcome to the forums! OK back to work I wonder if there is a termanology issue here? the OP says he does not want to change shifters and derailleurs but is asking about a freehub. I suspect he is confusing they types (or likely some Fred mechanic got him screwed up)
this is a stnadard or "freewheel' rear hub, meant for use with a threaded freewheel. most likely what Robo has now. (yes I know you C&V geeks know the difference this is for the OP)

and here we have a "freehub" meant for use with a cassette.

there is no reason Roboleg could't use a freehuband continue to run his friction system. he will just have a few more gears.
there are lots of nice Freewheel style hubs on Ebay and in the trade and forsale sections here. also Roboleg unless you are doing the work you may want to shop for prebuilt wheels. labor and spoke cost can really ruin a 'good deal' on a pair of rims.
OH YEAH what randy says is uber important. if you go with the wider freehub gt that frame respaced

Thanks for all the info and the pics help.
Yes I have "freewheel' rear hub, meant for use with a threaded freewheel on current 27in rim.I want to replace the freewheel with "freehub" meant for use with a cassette. I know how to respace my frame for larger hubs and brake reach is not a problem. I already have set of Mavic cxp22 with 32 spokes and my old rims are 36 spoke. Lbs guys are great guys but they are into new and not rebuilding vintage. They are unaware of a freewheel rear hub that I can put on this new mavic rim.

In general, any "new" freewheel hub will be pretty low quality:

Or outrageously high quality:

Or you can shop around for NOS (new old stock) hubs to match your rims. There's plenty around.
