Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them.

Anyone tried the new Mavic Open Pro UST rims?

I'm about to build up a set of all-round rim-brake riding rims. I have some DT-Swiss 240 hubs (32 spoke) and was looking at the lacing them up with either DT Swiss 411 or 440, H Son Archetype or perhaps Hed Belgium rims. But then I saw the new Mavic Open pro UST rims. Weight and price ($100/60Euro/430gr) look reasonable and they are wide too and they can be made tubeless as well which I may do when my existing tires wear out. But I've not seen many user reviews so has anyone used them or had any real world experience with them?
PS - I could not find a published ERD of these rims and so contacted Mavic support who said they are 589mm but I'd like to confirm this before committing to buying spokes.

I own a pair of Open Pro CD with Ultegra 6500 hubs built up in the late 90's. Still going strong. I believe Mavic Open Pro rims set the bench mark for bomb proof rims!

That's nice, but do you have any experience with the new Open Pro's Mavic released this year, that OP is asking about?

I have been thinking about some new rims as well so thanks for the thread. A lot of guys in my club have gone with the newer wider 24mm/25mm rim style and love it. One guy had the HED's and said it made a huge difference, others have gone with Boyd's . Overall Easier to mount, less pinch flats, better ride, more aero , etc.

I haven't done it yet, but found an excellent article from wheel builders doing a comparison, including the HED. For me, The choices are down to H+ Son Archetype, Pacenti SL23 (now Forza), or the HED's. Alloy Rim Roundup - Fairwheel Bikes Blog

The new Mavic's are interesting, they will be the widest out there if the claimed specs are true ,
The symmetric rim brake version design itself is wider, with a 19mm internal width (26mm external) and 23mm height to deliver greater strength, wheel stability and better handle the larger tires popular today.
they still use eyelets though, and those have always (eventually) for me eventually come loose and broke in their open pro rims(the rim review mentioned the same thing). For me, for this reason, I will not be using them

The Open Pro UST Rim has the famed UB machined brake track, and employs the Open Pro standard Stainless Steel eyelets to increase rim strength and durability
please let us know what you do and how it turns out

Wait, you can't rely on the manufacturer to tell you the ERD, but a guy you don't know on the net can advise you? That's bizarre.

Folks, who want to get it right, wait to order the spokes until they can measure ERD themselves on the specific rims they will be building with.

Eyelets coming loose? I not only have a set of Open Pro CD rims built up in the late 90's, but also have a set of Mavic MA2/6500 hubs that are about 2 years older. Both have eyelets and still holding strong. Open Pro with eyelets was once the choice for the classics years ago because of....durability!

+1.

Unless you are getting info from a well respected wheelbuilder or a shop like BHS, measure them yourself when they are in your possession.

Thank you!

I had to bite my tongue when I saw that comment. I've got several sets of old Mavic wheels and have yet to see an eyelet problem. Not even with the Open Pro's.

The reason for the ERD question is that I have a bunch of new 290mm spokes (enough for fr wheel) and I'd like to utilize them for this build and save some $ on buying all new spokes as well.
I saw on a site that the ERD was 593 (perfect for 290mm spokes) so I emailed Mavic support for confirmation but they said they were 589. I then emailed the site to see if they were aware they had a conflict on the ERD and I just now got an email reply where he said "Its not 589mm or the spoke I use to build the wheels would be too long. if you use mavic's ERD dont complain to me about having the wrong spoke lengths. "
Anyway, I guess until Mavic publishes an official figure, it's prudent to measure them yourself.

I don't think they fail from old age. how many miles on your wheels ?

Many miles. Bottom line is, wheels built with eyelets are much more durable that those without.

Let's see, pretty sure I have over 25,000 miles since say 2010. I've had one rim fail and that was several cracks at the spoke holes on the original rear of my Williams System 30 wheel. Yep, no eyelets.

And not a slam on the Williams wheels. I put plenty of miles on those over the 190 lb weight limit on really rough roads.

mine went 10K , no more than 15K, and the little rolled over part on the spoke side would break off and rattle on the spoke. That was easy to ignore, but like the article I linked to said , the rim would crack around the eyelet area eventually. Not to say this wouldn't have happened faster without the eyelet, but I don't see many new rim manufacturers using them anymore, must be a reason for that?
BTW, I had one with the slag too

Mavic Open Pro


Thoughts: The old guard. The Open Pro has been around for a long time and seen very few updates during those years. It’s typically not a rim we choose to build on as we think there are plenty of better options but decided to include it in this review for comparison sake. The Mavic does have a nice brake surface and a good classic look with eyelets. However it seems to be a bit more prone to cracking over time than some of the other more modern rims. Eric: Nice rim when it was more widely used. The later rims I worked with weren’t as round and consistent. Lots of complaints about rattling slag by the joint. People have resorted to inserting foam into a small hole by the joint to stop the rattle since the pieces have no way of being removed. Eyelets have been known to loosen up and make noise as well. I’m not really sure why Mavic even makes these rims anymore. They are clearly interested in selling wheels, not rims.

Sweet!

I'm curious how these will go over in the marketplace. With an internal width of 19mm, Mavic recommends a minimum 28mm tire. Are roadies ready to move up to even wider tires, since they're still getting used to 25's?

Yep, when I was researching using the Open Pros for a new wheel build a couple of years ago I found claims to newer versions cracking. But most were more of the "I heard" they crack, not actual incidences. Time will tell if it was a wide choice. For me though I normally shoot for a wider rim if the bike can take it.

But no real worries about any of my old eyelet Mavic Rims.

the Open Pro classic rim will always have a special place in my memory. When I started riding seriously early 90's they were THEE rim to build on, and I think they kept that place for a very long time. I'm certainly not saying they were a bad rim, I'm a Clyde and they held up pretty well overall. At anywhere from 220 to 240 pounds gear masher I eventually break everything, seats, pedals, frames, etc.
It will be interesting to see if Mavic takes top billing again with the new UST's . A nice looking rim, I notice they have gone away from the classic double eye-let spanning the rim cavity, opting for a single at the nipple seat.

another thought came to mind , if your putting a 28mm tire on a rim that's 19mm internal width, how many Carbon racing frames will even accept that without rubbing ?
Excel is 10 minutes from my work down a bike path, should I pop in there tomorrow and chat?

Please do, and confirm for us if they're even available; I thought they were not released yet.

Regarding width, I'm super-content running 23c rubber on 19.4mm internal width rims, and if the Mavic RUST system wheelsets come spec'd with 28s-- though OPro is not available as wheelset, what are Mavic's RUST tire options?-- it would cause me to rethink choosing a pair because, yeah, clearing forks and calipers is a real problem. But, I really want to try RUST...

I didn't catch the move to single eyelets until you pointed it out. Perhaps Mavic actually put a little more material right around the nipple holes, so only single eyelets will be needed to do the job.

The old-style Open Pros are now called "Open Pro C" on the Mavic page. Does anyone know if they'll keep making them for legacy users and frames that can't accommodate the bigger tires? (Or is this just to humor anyone in the distribution chain that still has some left to sell? )

They are certainly available. I just ordered 2 from Excel at $85 each (and thanks draganm for the 15% discount tip). I hope the 28mm minimum width is a bit fungible as I want to initially use my Conti4000 25mm on them. A 28mm minimum seems pretty wide for a road bike (and max is 47mm) and I also wonder how many road frames (or caliper brakes) can take tires this big.

The ones that haven't been released yet are the Exalith ones with the all black rim. Regular ones are already available.

Ah, thanks, guys. I only saw the Exalith ones Mavic demo'd on that sweet Stinner for the launch, and didn't realize there were machined sidewall version.

It's funny that Mavic has released the OPro UST, recommends a 28c tire, but has not released the tire yet. At least, the US site only shows the 30c Allroad tubeless tire, and the Ksyrium and Cosmic USTs wheelsets, which are 17mm bsw, come spec'd with 25c Yksion Pro UST rubber.

Your right... that's what I was thinking.

26mm external width.
Looks good for making 29er gravel wheels.
I wouldn't consider these for road wheels.
This fad of going wider has to stop.

Is there anyone with hands-on experience regarding the rim's ERD? I'm also wondering whether it's 589 mm or 593 mm.
