Hi All, SRAM have released a XX1 XG1199 11 Speed 10-42T MTB Cassette and its for sale here ... http://www.chainreactioncycles.com/Models.aspx?ModelID=91007 and http://www.chainreactioncycles.com/Models.aspx?ModelID=91023 ... does anybody know much about SRAM new 11spd cassette and RD to go with it :)

I know this is a MTB cassette but is SRAM intending to do something similar with their road cassette ...
... The 42t sprocket is huge and it can apparently be as large as 44T. With a sprocket that large there should not be an issue with the RD cage striking the spokes.
... So one could run 10-44T cassette with 44/46T crankring for a road setup, although the largest crankring for the MTB setup is 38T :)

Here's a bit of info on the RD ...
SRAM XX1 11 Speed Rear Mech Technologies:
  • X-Actuation - Designed specifically for SRAM XX1, X-Actuation keeps shifting sharp and consistent across the entire 10-42T cassette.
  • X-Sync - A "wide tooth, narrow tooth" pattern is repeated around the pulley wheel, perfectly mirroring the chain's inner and outer links for maximum control.
  • Cage Lock - With Cage Lock, wheel removal and installation - becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place.
  • Roller Bearing Clutch - Roller bearing clutch technology eliminates derailleur bounce and chain slap without sacrificing precision.
  • X-Horizon - Straight parallelogram design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.
It would appear that there are no wheel compatibly issues, only the need for a compatible XD Driver freehub for your wheel ...

XD Driver freehub - The XD retains a portion of the current splined interface, but adds threads on the outside of the freehub body. The X-Dome cassette has an internal sleeve that acts like an integrated cassette lock-ring. To install, one simply places the cassette on the driver body and uses a Shimano lock-ring tool to spin the internal sleeve onto the freehub’s threads, securing the cassette in place.

In an industry awash in competing standards it’s refreshing to see a company develop a new technology that places an emphasis on minimizing compatibility issues. The motivation was less of an act of altruism than it was a sound strategy to ensure that this new freehub standard would gain widespread acceptance. To this end, SRAM has made the technology open to all hub manufacturers who agree to follow the tighter tolerances the XD driver body requires. The manufacturing details and a list of companies who have signed on to XD driver standard can be found at http://www.xddriverbody.com. This list currently includes Mavic, DT Swiss, Bontrager, Specialized, Syncros, Easton, Stan's, Hope, FRM, Tune, Novatec and Crank Brothers.
It appears to be that the road version will be released here ...

SRAM Sea Otter Road Classic Race, Friday and Saturday, April 19-20, 2013 ... All Road Race categories will start on Laguna Seca Raceway at the Sea Otter Bridge. The route continues down Barloy Canyon Road to the classic Fort Ord race loop. After completing the required laps for your category, you will climb back up Barloy Canyon, to its crest, for a mountaintop finish. Sea Otter Classic is part of the Northern California and Nevada Cycling Association (NCNCA) series and NCNCA point system.

It should be excellent for Grand Fondos, Touring, CycloCross, and theoretically requires less maintenance and appears to be more durable and overall lighter :)

What do you think ...
 
If it's possible to use it on a road bike, there won't be many hills on which the 44/44 is necessary.
 
The following MTB reviews are some of the things they are saying :)

.. there are many more SRAM XX1 reviews and they are all glowing and high praising :)

Be interesting to see what SRAM releases for Road bikes ...

Hi alienator, what about touring with loaded paniers, commuting, cyclocross, and mountainous Grand Fondos :)

Touring, yeah. The others, not so much. A motor driven crank like Cancellara used to win Classics would be much easier. ;)
