SRAM's X0 cranks use a foam backbone instead of aluminum for better weight savings. These carbon cranks are strong too--keep an eye out for them on the World Cup Downhill circut.
The new X0 cassette borrows its good looks from the XX X-Dome.
But instead of being machined from a solid block of steel, the X0 cassette uses stamped cogs pinned together.
The back plate of the X0 is just a tad thicker than the XX as well.
The X0 rear derailleur keeps a lot of its previous styling, but is more refined and durable.
SRAM's front derailleurs have come a long way.
X0 is the only group so far to get its own Avid brake.
The X9 crank arms are hollow forged.
All of the new 2x10 cranks will be available for BB30.
The X9 cassette looks similar to the X0 and XX models...
But the X9 uses a spidered design for the four largest cogs.
The X7-level S1400 cranks are hollow forged, but to a lesser extent than the X9 model. The X7-branded cranks have a triple ring and are not hollow forged.
The X7 cassette.
The X7 cassette is similar in construction to the X9.
SRAM launched it’s new collection of 2×10 products at the Ashland 12-mile Super D event.
In the few days before the Super D, we flogged the X0 through just about every weather condition. Kirt and Lindsey Voreis.
SRAM's X0 group was designed to better serve trail and all mountain riders (as opposed to the race-oriented XX group).
