INTERBIKE 2009 – Besides the crazy light R-Sys Ultimate and CrossMax Ultimate we’ve already shown, Mavic had new and updated wheels across the range, from downhill to cross country to road.
Shown above is the R-Sys Red, which replaces the original R-Sys wheelset.  It uses round, not bladed, Zircal alloy spokes on the rear drive side and the TraComp composite spokes elsewhere.  Weight is 1390g (590 F / 800 R) and MSRP is $1,400.
Other new and updated models include:
- R-Sys SL (apparently, the everyman’s wheelset!)
- Cosmic Carbone SL – now in White
- Ksyrium SL – now in all Black
- Aksium Race
- CrossMax ST Disc
- CrossMax 29er – new axle options
- DeeMax Ultimate
Hit ‘more’ to see them all and why you need a set of $2,000 R-Sys SL wheels for your bike…
In case you’re curious, here’s a little info on the R-Sys wheels.  First, “R” is for Roue (Wheel) or Roule (Roll) and “Sys” is for system, as in (duh) Wheel System.  The key difference in R-Sys wheels is that the spokes provide resistance against the rim as well as pulling on the rim, creating a theoretically stiffer wheel.  The inside of the hub (above) shows how the TraComp spokes are held in place.  First, they’re slipped through the holes from the inside, then the silver ring goes in to hold them against the inner rim wall and also provide a platform for the spokes to push against.
So, back to the R-Sys red.  The red hub and red graphics on the rim visually separate it from the new R-Sys SL.  The redesigned TraComp spokes (which we’ve covered in great detail here) are said to be 4x more impact resistant.  Mavic seems adamant that any past mishaps with the new design were isolated, random events and are fully behind the TraComp spoke technology.
The rims are machined out on the spoke surface.  The R-Sys SL version gets the sidewall machining, too.
