Mavic Open Pro Road Rim for a clyde?

Hey all, im back again! Just working on picking out the last few things for my bike upgrade (upgrading some parts on a stock 2006 LeMond Etape) Anyways I was looking into getting these Mavic Open Pro Road wheelset, they seem like they would be solid...and I have the option of picking the spoke count so I am thinking about going with 32 for the front and 36 for the back...I know that many people say that spoke count doesn't matter but I am still planning on getting the higher spoke count since some of the roads I ride on aren't the greatest for those "flashy Aero Wheels" As I like to call them! Anyways I am looking for some input on these wheels and would like to know if anyone here has used them?

yup, many. Many swear by them, I couldn't keep them true (6'3, 230) and ended up with deep-vs.

Weight? type of riding?

construction (machine vs. hand-built), hubs, spokes and nippples are all big factors.

But spoke count does matter. How heavy are you? I'm 205ish, and builders have recommended 28/32 for me...

Hey guys, thanks for the replies, I am about 220 I think, and I am around 5' 7" or so. I will be using it for the road bike...I am not racing but I am going to be starting a "training" program soon to lose some weight.

I've had OK luck with Mavics, but better luck with Velocity Synergy rims and Shimoano 105 hubs. I weigh 220 also.

I'm nearing the below 200 lb. mark and I have a xero-lite wheelset that I've put over 1500 miles on and so far they are still true. I was between 205 - 215 most of those miles. Spoke count 20 rear, 16 front. 2 century rides and 2 group rides of over 70 miles included. I've had them less than a year though so still not sure how long they will hold up but so far so good.

question for you guys, where do you get your wheels? Do you order them offline? I don't have a LBS around that builds wheels....

Even more important than rims are good quality spokes. Remember, it's spokes which break not rims.

The most important is proper spoke tension, most machine built wheels, have too low tension. When tension is too low, the spokes at the top of the wheel allow the rim to flex slightly, this makes the spokes on the bottom of the wheel effectively too long, forcing them to bend slightly, when spokes are constantly bending like this, dozens of times per minute, they break at the end. The distances involved are extremely small, we are talking a few hundredths of a millimetre. The lower the spoke tension, the more each spoke is affected. The fewer the number of spokes, the more each spoke is affected. The heavier the "load" on the wheel, the more each spoke is affected. The more flex in the rim, the more each spoke is affected.

There are of course mechanical limits, where the flex in the rim, spoke count, wheel load, overcome even the most optimum tension, but we are probably talking extremes here, 8 spokes on a 125g carbon rim, with a 200kg rider, would do it, but those are extremes in all directions.

If you want light weight rims, and low spoke count wheels, then prepare to invest in having the wheel tensioned and trued by a professional wheel builder before you ride it the first time, and rechecked, by the same wheel builder on a regular basis. If you want install and forget wheels, then go for heavy weight, stiff rims, and lots of spokes.

Wheels are a system of parts. Only as good as the weakest, so beefing up on one part may not deliver the intended results. Having said that, Open Pro rims are ubiquitous and not bad (I have a set, but were the wheels not so damn cheap would've selected a different rim), I'd steer you to other selections. Which one, exactly, depends on a host of things you haven't specified like, rider weight, budget, priorities (weight vs durability), and use.

I have all the rims listed above..

Mavic Open Pro - Good Solid wheelset, go with higher spoke count..
Velocity Deep V - More rigid and lateral stiffness but a little heavier than open pro
DT Swiss RR 1.1 - Just as light as open pros with the stiffness of the deep v

My recent wheelset if DT Swiss RR1.1, as light as open pros but have a little depper profile, not as deep as the deep V's but just as stiff..

I'm 6'6" and 230 lbs and have a set of Open Pro 36 spoke on my cross bike. The builder tensioned them for long easy rides and they have over 4000k on them without truing. Great wheels for me and my style of riding.

I was going with the Open Pros...I am 6'4" at 230. I had a long discussion about this on the mechanics site. The end result...Deep Vs or the DT Swiss 1.1s. Have them hand built and some good spokes. If you happen to break one, you may well be able to ride it home. Not so with many machine built wheel sets for reasons explained above. good luck

My "light" wheelset has Mavic Open Pro rims. Both are 32 spoke with Shimano 600 (Ultegra) hubs. I'm still running 7-speed freehubs. These seems to be as strong as my "everyday" wheels which are Mavic CXP-22 rims with Shimano RSX hubs. Both sets were built by the wheelsmith at my LBS.

Then you are an exception. Were you dropping off curbs or mountain biking when you broke your rims, or just riding along?

no just riding along -- pulled the spokes out the rim on both, both were road rims.
one rim was a bontrager select (some rumor of a bad batch of rims on the selects) had about 2000 miles on the rim. Bontrager wheel department said it was impossible (I love statements like that in the face of hard evidence) recognize that bontrager/trek market these wheels as bullet proof. This rim was exclusively on my road bike.

The other is a bit more perlexing as it was a 36 hole open pro with about 5000 miles on it -- same failure pulled several spokes out. I know there are several people on the forum that have said there is a known weakness with the open pro eyelets. I'll just leave it at that. Mavic replaced the rim and my LBS rebuilt it. This rim was on my 'cross bike (commuter/raced it a couple of times/ride some trails on it) obviously it sees a little more abuse than my road bike rim would have.

I also have a 32 hole open pro that I have fewer problems with (primarily been on my road bike since I gave up on the selects) but it probably doesn't have near the abuse or mileage on it.

The one spoke I have broke was on the second select rim(after they replaced it and my LBS rebuilt it) he stress relieved and retensioned it several times before he let me ride it though. I gave up on the wheel after that (Its on my wife's bike now)

I am 6' 6" and have ranged between 275 # and 250# since riding currently 255. Obviously I'm not gentle on anything. but the rim thing has always perplexed me a bit. both were rear wheels(obviously the weak link for wheels) I don't think I have ever had problem with a front wheel.

Hi,
I weigh 250 and I like speed. What worked for me was Mavic CXP33 rims.
They are like the Deep V. Incredibly strong, the only time I got the wheel out of true was when I hit big holes going real fast.

The nice thing about the CXP33 is that they aren't heavy. At 470gr they are 35 grams heavier than a Open Pro.

Match them with a good hub, and you can't go wrong.

I have a set of Mavic Open Pro rims, Ultegra Hubs, and DT 18GA 32 crossed 3x. They don't spin up as fast as the 16 spoke stock rims, but I can climb hills now and not worry about busting a spoke.

I got mine at Colorado Cyclist.

I broke a Bontrager Race Light rim (~4,000 miles) with bladed spokes and Trek replaced it. Then I started poping spokes. I then went with Mavic Open Pros with 32 spokes laced to an Ultegra hubs (ordered from net). I had trouble keeping them true until I had a local bike mech true them and he then he used lock tight (green I think). Never had a problem until a few days ago (3,000 miles later) when I was riding and noticed my rear wheel was wobbling. I got home and went to adjust it and found I pulled one of the spokes partially through the rim.

I talked with another mech and he suggested the CXP33's which is what I plan to replace my rear wheel with.

IMO at 250 lbs I think I (many of us) the load just simply fatigues aluminum rims and causes stress cracks. Local mech quoted me $90 for CPX33 rim and $40 for lacing.

My current thoughts are to build a DT R1.2 rim with alpine III spokes, but I'm not sure on the hub -- I'd be happy with an ultegra hub but I read somewhere the holes aren't big enough for the alpine III spokes. I'd lace the rear 32 3 cross and the front 28(might even go with an R1.1 front)

The fatigue issue could definitely apply here and also stress corrosion cracking (My rims were run in the winter and rain)

On the fatigue front a 32 hole RIM would actually be stronger than a 36 hole RIM (fewer holes=more aluminum) That is discounting the wheel as a system -- I am strictly looking at the strength of the RIM (trying to avoid the flames )

Go with spokes that will fit a standard hub. Spokes today are great, the problems like elsewhere, IMO.

Give us updates on those rims. If they work out for you, I want to try them.
