Granted, this leaves no provision for at-home truing or repair but unless something actually breaks, there is no reason these should go out of true anyway.
Either way, interested buyers shouldn’t hold their breath. As of right now, only 10 sets of these wheels are currently in service and all of them are slated for the Liquigas, Ag2r and Silence-Lotto teams.
Durability issues highlighted by the original R-Sys have been addressed with new nine-layer spokes augmented with four spirally wound outer layers plus an extra pin inserted at the nipple end for additional shear strength.
Mavic claims impact resistance has gone up five-fold as a result and torsional strength more than three-fold, bringing the once-fragile carbon spokes more in-line with the bladed Zircal spokes used in its Ksyrium range.
Strong enough for ya Captain Commuter?
What’s funny is that they say the carbon spokes are now as durable as the aluminium Zircal spokes- but everyone knows Zircal spokes have a lifespan of perhaps a couple of race seasons haha!
The undisputed star of the group is the new ten-speed ‘X-Dome’ cassette weighing in at just 208g - 42g lighter than XTR even with XX’s extra cog. Like SRAM’s road-going Red unit, XX consists of a nickel-plated CNC-machined 4130 chromoly ‘dome’ - reportedly requiring nine hours each just to mill - mated to a 7075-T6 aluminum backing plate only in this case, radically aggressive machining leaves just a sparse lattice of material that mud and debris can easily push through - a common complaint from the cyclo-cross crowd on Red - and the similarly milled-out backing plate on XX now also doubles as the largest cog.
I’m no production manager, but 9 hours to mill out a freaking cassette seems kind of excessive doesn’t it?! :-o
Sorry mate, should have made it clear I was referring to the road ‘Wheel Systems’. I have no personal experience with the mtb wheels but have heard only positives things.
Riding with the skewers tensioned as such was fine. They stayed in place with no problem. Sprinting, riding over curbs, rough roads, etc. Then we raced. Our second race on them we drove through a pothole while leading a strung out field – too many wheelsuckers – and we heard a snap and the rear wheel came loose. Yikes! We soft-pedaled to the pit and took a look. The skewer nut and nut-side spring were gone and the wheel was barely in the vertical dropouts. Rather than change wheels, we asked for a spare skewer. We were accommodated and we finished the race without incident.
The elephant in the room is whether or not this is smart weight to save. Skewers aren’t involved with rotating weight, so it isn’t as big a priority as wheels.
but then they contradict themselves at the end of the review :?
When you want to have the lightest bike in the pack, these are indispensable because not only are they crazy light, but they’re super strong, so you’re not making a sacrifice, except in the wallet. Lightweight has upheld their tradition.
How dumb is this product? Of all the components to reduce weight, why the hell would you choose an ultra critical fastener like a skewer?! As the review shows, the freaking thing failed in normal use.
But what’s even dumber is that the reviewer still gives the product a glowing review!
It’s like if you reviewed a carbon frame, and it smashed into pieces when you rode it, but you still recommend it at the end of the review?
Weak as piss light skewers are nothin’ but fucking tinsel like on a christmas tree. Just another one of the big $$ items that make your bike worse. DT ratchet skewers rock.
