Hey Guys,
The mystery is over. The Mavic 650W Rim is a 27" rim. Why in the world Mavic didn't label it as such is a mystery to me, maybe it's a French thing? Here are the pictures, here we have an MA40 700c, Module "E" 27x1 1/4", and the Mavic MA650W. You can see it has the same outside diameter as the Module "E".

650W has nothing to do with size, it is a reference to their anodizing process

There are two archived threads which:

A. Fail to address that fact
and
B. Never determine what the ERD of said rim is.

Question is, did a 700C variant of the MA40 exist with the confusing 650W (650 watt?) decal on it? Might as well have this data for reference to prevent folks from getting confused.

Mavic could have avoided all of this by simply putting 27" next to the 650W. I would like find another.

I have a wheel with the exact MA40 rim and confusing 650W label that has a 23-622 (700x23c) tire very nicely mounted on it...(BTW, I'm looking for a match.)

It gets better....I have a 650C (size!) MA40 rim that is marked '650W'. I also have a pair of 650C (size!) Open4CD rims that are marked '650V'. They are all anodized.

Does anyone know if the ERD of the MA40 is identical to the Open4CD?

All right - there we go: MA40's with the "650W" treatment decal (i.e., 650W has nothing to do with the size) can be found in the following sizes:

700C (622)
27" (630)
650C (571)
26" fractional (559)


EDIT: Added 26"/559.

Anybody have a 27" Ma40 they would like to get rid of?

Not before you find me that 700C Super Champion

I've got a pair in a 26" (559), they're pretty great though.

Wait! I have an MA40 MB that was sold to me as a 650c. But I compared it with a 26"/559 rim and it looked the same (and a 650c tube draped over it like saggy boob), so I thought it was a really thin 26". When I tried mounting a a 26" x 1.4 (or 1/4? the labeling is weird), it was pretty much impossible to get even one bead on, and am now thinking of the possibility that it actually is a 650c (or b?) Though the 26" tube looked like it fit nice and snug...

For reference sake I have seen a 26" MA40 with a 26" tire mounted on it so a 26" definitely exists. I am curious whether it's 26/559 or perhaps a slightly different 26 ie. the old cruiser types.

EDIT:
Okay, this could be a crazy idea, but:

I've been looking into this alot lately because I really wanted to use this wheel. There definitely exists a 26" and 700c version. I had yet to see a 27" version discussed except here, and I believe this thread is the second time I have heard reference to a 650c version. Now, most of the 26" model owners noted that the majority of tires they used on it were extremely difficult to mount. Is it possible that it's a slightly large 26" rim that is capable of being mounted with slightly small 650 tires in the 650 model scenarios? I don't know much about 650s but I hear there are 2 different types, 650b and c.

I just returned from the LBS. My apparent "26" or "650c" MA40 will not accept a 559mm (too small) or a 571mm (too big).

WHAT THE HELL???
