The Mavic R-Sys SL Wheelset blends new composite and milling technology, new aesthetics, and further weight savings to result in a new generation of Mavic's most distinct road racing wheelset. With their low inertia and low overall weight, you'll feel the R-Sys SL sparkle when you accelerate. This is a plus for thrashing through a 60 minute downtown criterium or for grinding up extended climbs. They're also pleasingly stiff for bigger riders.
This SL version is nearly 100 grams lighter than the standard R-Sys. A good portion of that savings comes at the rim thanks to Mavic's ISM 3D milling process. Where they've historically removed excess material from the flats of the rim between the spokes, this 3D process also removes weight from the shoulders of the rim above the brake track. And though weight savings at the rim is the most crucial in terms of sheer performance benefit, saving weight is always a good thing when you're fighting gravity. The hubs are lighter because of their use of carbon centers and end caps, and the titanium-shafted skewers save an additional 10g per wheel.
What separates R-Sys wheels from the norm are the spokes. Mavic calls them TraComp, and they're made of tubular carbon-fiber. Their design is notable in that they have a sufficiently large diameter to work both in tension and compression. ...with their low inertia and low overall weight, you'll feel the R-Sys SL sparkle when you accelerate... This is the quality that allows them to have unmatched lateral stability. This will translate into confidence inspiring descending at speed. The front wheel uses 16 of these carbon spokes while the rear has 10 on the non-drive side. They're too large to be used on the rear drive-side; 10 bladed Zicral aluminum spokes go here instead. Using this few spokes means a very light wheel, in fact, lighter than many carbon-fiber wheels designed for sew-ups. However, the Tracomp spokes allow this light weight without sacrificing the stability of the wheel under load.
One intriguing feature is that the front wheel has a shallower profile than the rear. Mavic found that pros like shallower-depth rims in front for greater control on sinuous high-speed descents. So they made the R-Sys SL with a depth of 22mm in front and 25mm in the rear.
The Mavic R-Sys SL Wheelset is for clincher tires only and available to fit Campagnolo and Shimano/SRAM cassettes. The rims are made of Maxtal aluminum alloy and are milled for weight reduction. They run on Mavic's QRM SL bearings and have aluminum axles. The front wheel has a speedometer magnet built onto a spoke that can be slid up and down. Mavic's BR601 titanium-shafted skewers are included with the wheels, as are Mavic wheel bags, a spoke wrench, and a Tracomp ring removal/installation tool.
This wheelset is part of Mavic's MP3 extended warranty program. The acronym stands for Mavic Product Protection Plan, and it provides you with two years of almost unlimited no-fault protection from Mavic. More details can be found on the MP3 website. Please note that MP3 coverage must be purchased within 5 days of the date that you receive your wheels. Contact one of our customer service representatives for the retailer and product codes that you'll need to register your wheels on the Mavic MP3 site. You'll also need the serial numbers that you'll find on your wheels. The cost for this coverage is approximately 8% of the retail cost of the wheels.
- Exalith treated aluminum alloy reinforces the rim to allow minimum material for an ultra-low rotational weight, and reduces rim wear from braking
- Tracomp carbon fiber spokes reduce deflection and for enhanced efficiency, and steering accuracy
- FTS-L Force transfer system pawl and hub body interface provides instant engagement, and optimum power transfer for quick sprints

I have a 2009 post-recall pair of R-Sys. I highly recommend NOT buying them. Rear rim cracked after a year ($400 repair) same as being reported on Ksyrium models (Google Ksyrrium crack). Locking rings on the front (to hold spokes in place) have broken 3 times and Mavic wants $200 to replace all the spokes.
As for the Ksyrium cracks - my LBS had 5 wheels in the shop that he was going to send back to Mavic because he doesn't want to be responsible if they crack again.
Any weight restriction for this wheel? I usually weigh just under 100kg.
No, but it's hard to get an exact on weight limits anyway because the nature of the riding is usually a more important factor than only taking rider weight into account. Also, wheel companies want to do as little warranty replacement as possible so they don't want to replace a wheel when you jumped off a 12-foot cliff and cracked your rim in half just because you are under the "rider weight limit." Even the lightest weight limit wheels will hold up under just about all road cycling conditions for everyone except possibly professional riders and their higher wattage output during sprints. Yes there are static weight limits on wheels where the rim will break/buckle under a certain static load (i.e. no movement just added weight), but that's more like 1000lbs. because the jarring it will take when riding will mimic these kinds of forces on a 175 or 250 lb rider on certain impacts/bumps. If you are concerned about potentially catastrophic failure (i.e. break in the rim throws you over the handlebars or out into traffic), I would suggest always "breaking in" a new wheelset by riding it under the easiest conditions first, getting used to the feel, flex, and the creaks (if there are any) and then gradually go more all out from there. Heavier riders will get more flex out of wheels, but they won't actually break. All wheels, even full carbon/carbon spokes, will flex quite a bit before they will fail/break so you should be able to tell the limits if you ever actually approach them before you actually break anything.
Have been riding the R-Sys wheels for some time and prefer these over any previous. Shock absorbing/comfy ride uncomparable, in my opinion.
