I recently picked up a rear Mavic MA40 700c Green label rim with an earlier 500 series Mavic hub similar to these.

Here is my broken axle:





The axle was clearly broken on the drive side but i got the wheel for a great deal so i figured if it can't be fixed someone might have interest in the hoop.

If someone has an extra axle please PM me. Or if someone knows where to find one for a decent price let me know.

Thanks!

Have you looked a ebay? If they don't have an axle, why not a good used hub you can use for parts?

I might have one of those (a used hub) what axle length: 120, 126, 130?
I should add: I've take these hubs apart to replace the bearings and it's a straight-forward job but you need a Mavic tool to remove one of the "dustcaps", if you want to do a clean job. You can mangle it off with crude methods (if you don't care about re-using it, since it will be ruined).

Did you ever find a replacement? I believe I have one.

Unworthy, do you have any parts for the 500 series Mavic hubs? I am looking for one of the "cups" that go on the axle end (black piece secured with circlip). It "grips" the dropout when the skewer is tightened.

Last year my rear axle broke. Had about 50k on the thing. Looked high and low for a replacement, but couldn't find one so I moved on. About 1 week after I discarded it guess what showed up on ebay? Since then it is the only axle or 501 hub parts I have come across. Hang on to it for a few years and you might get lucky!

Is this the hub of concern? If so, I have one. PM me if interested.

Randy, I don't have the 50 posts required to send PM, so I am responding here. When you say you have one, do you mean the entire hub as shown in your post, or the cup at the end of the axle that I am looking for?

I might have just the axle end ("cup") you are looking for, but looks like Randy is much better organized so I suggest you work with him first...might take me a (long) while just to locate the part or discover I can't!
BTW: front or rear?

I have the hub as shown and nothing to go with it. It will be reasonable, if you are interested. You can send me an email through my website (see below) if you wish.

My favorite wheelset has Mavic 501 hubs and a 7 speed freewheel. I think I'll start watching for a replacement rear axle. I'll probably end up buying a whole rear hub.

Can you tell me more about this operation? I'd like to service my Mavic 500 hubs at some point in the near future. (Still using the original sealed bearings.) I figured I could use a small pin spanner on the dust cap, but this doesn't sound like it's the case. What is special about the Mavic tool? Thanks in advance.

I'll try to find the catalog scan that shows both an exploded diagram of the hubs and a pic of the tool: it's basically just a pin spanner, but sized just to fit the holes in the hub dustcap. Nevertheless I managed to break at least one (maybe 2) of the tools because that cap is fairly soft alloy; has fairly fine threading; gets bound tight with corrosion really easily!
If you do a lot of prep (soak in penetrating fluid, apply heat, chant to the bike gods) you might get it off without either stretching the holes or snapping the tool...if you do, then put it back on with some good grease or (better) anti-seize!

Edit:Velobase had a scan: this 670 is the good tool to use, it won't break. poke around the catalog scan and you'll find many exploded diagrams of the hubs, etc....LOVE that about Mavic!

Euro Asia says[appears on website] they still have some stock,
but they are a wholesale distributor ,so Go thru The LBS..
I have a 130, 501 NOS rear hub 36 spoke,Mavic, can sell.. never laced..

What is special about the tool is it engages all 6 of the holes..

Appears on what website?

Thanks for the good info and catalog link. What a funky looking tool, btw.

a plastic dust-cap tool comes with newer mavic wheel that has the same six hole pattern. I wonder if it is strong enough to work. They should be a dime a dozen in any modern road shop.

In my experience: NO, not strong enough (but YRMV).
There is also a cast-metal 4-pin Mavic tool with a 5-inch handle that's sold by Nashbar for modern Mavic hubs. It will probably break, too.
The all-steel 670 with 6 pins is the tool to use, if you can find one.

I am kind of glad that I posted a question here. It seems to have spawned a lot of followup. I had 2 wheels for sale that used 520 hubs. This is the fixed gear (or track) hub in the 500 series. I had converted each hub to 126mm spacing for use as a winter training wheel on a road bike. I advertised the wheels that way but said I would include the 110mm track axle. The first buyer wanted the 110mm axle installed-which I did. When I changed axles I noted that the 126mm (road) axle needed "cups" at both ends. The track axle had a fixed cup on one end. Converting the axle took my last cup. Thinking that the second wheel (unsold) would also require 2 cups if the buyer wanted the track axle installed, I posted here for a cup. Surprisingly, the track axle in this second wheel has removable cups on both ends. My need for a cup no longer exists. I do have 2 126mm axles if anyone is in need.

I did not know about this forum last year when my 501 axle broke. Could have replaced the axle through a contact here. I am so bummed! That wheel was sooo bombproof! The hub was slotted by Mavic for use in some teams rear wheel, too. It served mountain bike duty, road duty, and commuter duty. If I had only known about this place before I chucked it...I am very disappointed in myself. Darn!
