TruVativ X9 2.2 Crankset with GXP Bottom Bracket $0.00
With XX, SRAM finally made double cranks a reality for mountain bikes. One key element was the 11/36 10-speed cassette. The other parts of the equation were a dedicated crank/chainring set and matched front derailleur and shifter. And with this success, 2x10 has trickled down into other groups. This X9 GXP 2.2 10-Speed Crankset benefits from the ground work for XX, yet it delivers 2x10 performance and simplicity for a significantly lower cost. Truvativ uses a hollow forging process to make sure that the X9 crank meets expected performance/value criteria. Sure, their high end carbon fiber cranks are a few grams lighter, but their higher cost puts them off the mark in comparison to this one.
???benefits from the ground work for XX, yet it delivers 2x10 performance and simplicity for a significantly lower cost??? The hollow 7075 aluminum arms are ideal from a durability standpoint. You can stomp on the pedals as hard as you like and you know that not only will they resist deflection, but they'll be tough as nails. And if you ride in rough terrain, that's a nice thing to know when you tag the crank arm on a boulder.
Fitted to the aluminum spider are Truvativ's CNC machined 7075 T6 aluminum chainrings which include a highly refined set of pins and ramps to provide smooth shifting under power. A double-specific 80/120mm bolt circle diameter allows the four hole chainrings to be stiffer for more precise shifting, and trick dual-sided 5mm/6mm alloy chainring bolts make for easy work when it's time for replacement or service.
The X9 GXP 2.2 10-Speed Crankset uses the proven Truvativ GXP bottom bracket design. While the non-driveside sealed cartridge bearing is sandwiched between the left crankarm and a shoulder on the bottom bracket spindle, the other bearing is allowed to 'float' laterally, allowing for a zero preload arrangement that lasts longer and runs smoother.
The Truvativ X9 GXP 2.2 10-Speed Crankset is Black with Grey, Red, or White accents and is available in two crankarm lengths -- 170, 175mm. It's offered with either 26/39t or 28/42t chainring combinations. It must be used with SRAM's GXP or GXP pressfit bottom brackets (GXP included).

No, its not made of carbon. But yes, rocks will come to fear it. While the GXP bottom bracket seals aren't necessarily the best, this is a rock-solid crankset, reasonably light, and great value.
Worth for the money
Add to this crankset, a X9 front and derailleurs, and forget about to make any adjustment, this things are light weight and reliable.
