Almost bomb prove!!!
Damn good spokes (almost as thick as half a chopstick)
No rim strip needed
Weaknesses: Could be more aero
Plastic skewer tips get damage easily
A lil cheaper would be nice
Bought this wheelset after i broke an easton ea90slx, trained on it for a few months then I took it on a 3 months tour across the US and put almost 5000 miles on it. Went through pot holes, loose gravel roads, a few crashes, sun and a lot of rain then ended up at a beach in Seattle. Still spinning, quiet, tight hub and most importantly, still damn true. The wheel climbs well when i took it up some mountain passes and accelerates real well for a 1500~g wheelset. Control is very sturdy coming down 10-15 miles of descent, no shake whatsoever. Braking surface is pretty wide and tacky. However, its not the best wheelset for solo breakaway and holding threshold (if only it was more aero ehhh...). But overall a very very very tough wheelset.

Strengths: Looks, reasonably light, nice sound on the road. Great skewers with a really positive locking action
The red hubs look great
Weaknesses: I've hit one small pot hole with these and the front wheel is out of true. The ride is pretty harsh and the freewheel has a lot of drag. The front hub has a fair amount of play which I can't seem to eliminate. The wide spokes seem to catch a lot of wind for such a low profile wheel. They don't feel very stiff on the road.
Special tool needed for nipples
These came on a second hand Lynskey and they certainly look the part. Right from the word go, I struggled to steer the bike well going downhill. Uphill was great, but I could never get it to track well going into corners. I began to suspect it might be the wheels, so I swapped them out for a friends handbuilt set and the bike was totally transformed. Much stiffer, more controllable and the bike went exactly where I wanted to go, like I was used to with my Bianchi. No more cutting corners or worrying about on coming traffic.
I know a lot of people love these wheels, but I really haven't been impressed. After talking to a wheel builder we both question Mavics QC as some people get great sets and others get dogs.
I commute on the wheels, but my commute is up through quiet roads in the hills so I have an hours climbing from town to get home. Its a great ride and I thought these wheels would be better than they are.
They never really feel fast, but the garmin tells me I'm going as fast as I do on other wheels
I'll get them trued up and flick them on, and replace them with a handbuilt set which will be the same weight and stiffer.

Strengths: When I bought my Cervélo RS at the end of 2010, I wanted a lighter wheel than the Fulcrum Racing 7s it came with. I traded them in when I bought the bike and added a fair number of bills to get them. They're very decent looking wheels with the red hubs, mesmerising to look at when riding (viewed from behind, so I'm told), the one red spoke is sort of flash. Despite being very noisy wheels for the heavier rider, they remain true and the rims are strong.
Weaknesses: The problem is: I am heavy. And after riding 6000 km on them, I can say that Mavic wheels are not suitable for heavy riders. By heavy I mean between 95-100 kg (I am tall). When the bike was quite new, I noticed what I thought was the bottom bracket clicking, but after many months of thinking the bike was noisy, nope: it was the wheels. Whenever the bike went in for service, the mechanic would lube the spoke heads with HHS2000 and they'd be quiet for a few rides, then the click click click would start up again. SO ANNOYING! I am talking about loud clicks, sometimes 5 or 6 per revolution of the crank, and not just on hills, but also on the flats with no torque going through the chain.
I think the problem with the Mavic Ksyrium SL is that the design is backwards. The radial spokes are on the drive side of the hub and the angled/crossed ones are on the opposite side, unlike virtually every other wheel I've seen. The other thing is that there are 10 spokes on either side.
The Fulcrum Racing 1 Competition Limited Editions I replaced the Mavics with ($710 from bike-discount.de, delivered to my door) have 21 spokes and 14 of those are on the crossed/drive side of the hub....the 7 radial spokes are on the other side. A friend of mine of similar weight has 6000+ km on his Racing 1s (with the smaller hub) and his are still silent. Although I've not ridden these new wheels long enough to write a review, I am so relieved to not have that loud clicking all the time!!! Fulcrum rates them for riders up to 109 kg, and I am always 10 kg or more below that. I never did see an official rider kg limit for the Mavics but if there was one, I would think it's 75 kg.
I gave the Mavic Ksyrium SLs to my son, who is also tall but fortunately about 20-25 kg lighter than me. Even for him the wheels are noisy now that I've broken them in so to speak, but we will have the spokes retensioned to try and minimise that soon.
Weaknesses: Price? Road wheels are pricey, but compared to deep aeros and carbon tubulars these are a bargain.
I needed a laterally stiffer wheelset than the set that came with my bike, and if they were lighter it would be a bonus. I wasn't looking for the flashiest, lightest, aero, blah blah blah. Well, this wheelset is both, as well as plenty durable. They've taken quite a few last second "oh s***!" surprise potholes and nary a whimper. I bought the notubes kit and converted tubeless, and I have yet to get a flat since doing this almost two years ago (knock on wood!). The initial sticker shock is my only complaint, but compared to the entire road wheel market out they're reasonable. I could have shopped the web for the lowest price, but I will spend a little more to support my LBS. There are a lot of fashionista mavic haters on this site, but I have a couple sets of mavics on my mtb's, and despite years of abuse and no maintenance they've been extremely reliable. Another unintended bonus is they match my bike perfectly and look blingtastic, like they were meant for it.
I've had a lot of wheels at this point. Aksiums, elite's, ritchey, custom, etc. These wheels are really amazing. They ride a bit harsh, but they spin forever. They REALLY do make you faster. I went through a number of pot holes, but they keep going without a problem.
i have 2 sets of wheels, silver ksyrium sl at 1550g and assault clinchers at 1487g. ive been using the reynolds wheels as climbing wheels, but sometimes i wonder if the ksyriums actually have less rotational inertia. the rims on the mavics must be lighter, though the spokes are clearly heavier, an ...

[SIZE=2][COLOR=#000000]I am looking for a silver replacement rim for my Mavic 2003-4 Ksyrium SSC SL rear wheel. Can anyone point me to a source?[/COLOR]
Mavic does not have a suitable rim available and I have come up dry on eBay.
Here are some additional details.

I have a pair of sl's kicking around and finally getting into cross how would these hold up to the mud dirt impact of cross? Is it easy to run them tubeless or not bother. Any input is greatly appreciated. thanks!Read More »
Mavic recommends using their own mineral oil to lube the freewheel, bushing and rubber seal. I don't have it nor I can get it where I am now. What other oil could I use without creating more problems? I've heard that hydraulic brake mineral oil or 5w suspension fork oil would work. Any thoughts?Read More »
