MTB Reviews > Drivetrain > Cranksets > SRAM XX Crankset
Coming in at 694 grams (BB30), the XX Crank delivers amazing performance and durability with no penalties in weight. The first MTB crank specifically designed for 2x10 uses some of the world’s most advanced material science. The oversized chainrings are CNC machined 7075 Aluminum blanks—2mm thicker than the competition. Unparalleled stiffness is delivered by an increased Bolt Circle Diameter (BCD)
SRAM XX Crankset Reviews
Description: (from sram.com)
Coming in at 694 grams (BB30), the XX Crank delivers amazing performance and durability with no penalties in weight. The first MTB crank specifically designed for 2x10 uses some of the world’s most advanced material science. The oversized chainrings are CNC machined 7075 Aluminum blanks—2mm thicker than the competition. Unparalleled stiffness is delivered by an increased Bolt Circle Diameter (BCD)
and a two-piece insert-molded carbon composite construction. The XX Crank geometry provides a narrow 156mm Q factor, efficient chainline, and beveled crank arms to maximize clearance. It’s pure science in action.

Pros
I really like doubles they shift a lot better than triples. Light and very nicely machined
Cons
Nothing really someone brought one in that was undertorqued from the factory which lead to spider fracture.
Review
Nice and quite blingy great shifting.
