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. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

How many people have actually had problems with Mavic R-Sys rims?

I have had my R-Sys wheels for almost 8 months already and have not had any problems. I bought them before I heard any of the "horror stories" but, although they are not aerodynamic, I was looking for a light set of wheels and aerodynamic was not an issue.

I have seen the pictures and the video of a disintegrating wheel but, out of curiosity, how many of you have actually seen that happening in person or personally had a problem with an R-Sys?

It happened at a local race to some poor guy... I wasn't there but the stories were enough for me.

If they're not aerodynamic and fast what were they designed for climbing?

Yes. I live in Costa Rica, so I was more interested in climbing than aerodynamics

I have had several problems with mine. In fact my front is being sent back to Mavic right now for the second time with the same problem. As far as I am concerned, the design of the hub is fundamentally flawed, there is no way the compression ring inside can stand up to being ridden more than a few thousand miles before it gets hammered to ***** and starts rattling. It is supposed to be a tight fit, but when I opened up my hub they just fell right out. They are light but they are not durable.

For what its worth, I also had a set of Rovals Fuse SL that came with my Tarmac and was using those until I broke a spoke. When the Rovals came off, I went to the R-SYS first before my Ksyrium ES. The rovals, it turned out, hadn't just broken a spoke, the rim was cracked near almost every single spoke hole

Do you have any pictures of that? I'd be really curious to see it, especially on an aluminum hoop.

I was thinking about a pair of those, too.

When I get my next set of wheels they'll most likely be EA70's but I've had my eye on getting Ksyriums, R-Sys, EA90's, or Dura-Ace if I can afford them. Even though they're more expensive than my bike itself I figure I can upgrade them onto my next bike. I was bummed to hear such negative things about the R-Sys.

I didn't think to take pictures until after I left the shop. I didn't know they were cracked when I dropped them off for the spoke repair. Otherwise I've been very happy with them, much more than I expected, and will have no problem riding on my new set that arrived today They list kind of expensive though, what are they, like a grand? I'm not sure they are worth that.

Two local racers have had explosions in races this season. Just don't let anyone touch the spokes while you're riding.

why? there's so many good wheelsets out there, and so few to avoid. R-sys ans eastons are on the short list.

The r-sys makes you appreciate the durability of other carbon alloy wheelsets, particularly Topolinos.

Yeah. Seems that the entire line of Roval wheels is that way. I can get them EP though, so it's much easier to justify. That and it seems like they are always cheaper than MSRP on eBay.

Hey well we're on the subject I have a question for you guys. I thought that since the Ksyriums were a 10 speed hub they were out of the question for use on my 9 speed shimano bike. I went to a pretty reputable LBS and one of the guys told me that you can put a 9 speed cassette on a 10 speed hub. So I'm hoping to get a definitive answer on this w/o having to start a new thread. Can you put a 9 speed hub on say a Ksyrium or Ultegra wheelset?

yes. all mavic wheels come with a spacer to adapt a 10 speed freehub to a 9 speed cassette. Shimano probably does as well

Most 10 speed hubs are 9 speed compatible. Shimano increased the spline height for the 10 speed cassettes, so the Dura Ace 7800/7801 wheels have a freehub body that has 10 speed splines and thus 9 speed cassettes will not work. I don't think any manufacturers followed Shimano with this, since Sram still uses the old spline setup. Not sure if they did the same thing for the Ultegra range and lower; you could always bring in your cassette and see if it slips onto the freehub body.

Not all freehub bodies are 9-spd compatible. I know that a set of AC 350s I borrowed was not, and I've heard that D/A wheelsets have freehub bodies that are 10-spd only. The cassettes are narrower, so the 10s come with a spacer ring to push the cassette out a bit on a 9-spd freehub body. If the fhb is narrower for 10-spd, there's not room for a 9-spd cassette on it.

Mavic's site says their Ksyrium hubs are M10 compatible, which it looks like will accomodate 8, 9, and 10 spd cassettes. Search for "M10" here for a description:

# When using a Shimano cassette on M10 hub,a 2mm spacer is required(supplied with hub)
# Mavic M10 cassettes will not work on Shimano hubs

I bought my Ksyrium SL before I switched to 10-speed, so I know they worked with 9-speed

Thats great news...if I ever get that cash to throw at wheels. That also means the Ultegra pre-built wheelset is now possibly an option.

Did you see it? Not that I don't believe it, but the original intention of the thread was to separate the actual witnesses from the internet stories. While problems may exist, so far it appears that there is more hearsay than factual evidence

My team mates wheel failed completely when a pedal or something came into contact with the spokes just ahead of me in a race. Our sponsoring shop will no longer sell the wheels.

My sponsoring shop has had problems with every Rsys wheelset that has gone through the shop. He hates them.

Yeah, one was in the AT&T Crit that I won. He was just in front of me, three riders over. Someone's right pedal got into the left side of his wheel when he was trying to get away from the curb (he was out of the saddle, which made room for the other rider's bars. It sounded like several small explosions, and I thought: "R-Sys failure! Quick, find a spoke!"

Sure enough, one of his spokes was sailing right toward me. Man, that would be the coolest straw to bring home to the kids.

Anyway, he maintained control surprisingly well, skating on his rear dropouts at 30mph... until he wandered back into the gutter and hit a storm drain. He was down to maybe 10mph at that point, but it was a solid little endo.

I felt bad for the guy, but he wasn't hurt bad at all. Just like a parking lot crash or something.

The other one I didn't see, but I posted photos of it over in the racing forum. I raced M35+ that day, and the explosion was in the Cat 5 final sprint (another pedal contact).

No, the splines on that set are higher. AASHTA.

same team, same shop sponsor as Lith. team mate in question had front wheel spokes fail in the example cited above, rear wheel spokes did the same when someone rubbed their front wheel into his rear wheel. poor product, you've got to be insane to ride them, and downright foolish to purchase them.

if you've already got them, take them into your garage and break something on them so you're not temped to ride them.
