SRAM X9 has always been a rough and tumble kind of group, as at home on a blue collar race bike as it is on an all-mountain steed destined for a two week adventure in the Rockies. With this Truvativ X9 BB30 2.2 10-Speed Crankset w/Bottom Bracket, X9 isn't left on the porch with regards to new technology either. The 30mm alloy spindle makes this crankset one stiff beast, and with the bearings housed inside the BB30 bottom bracket shell, you'll benefit from more heel and ankle clearance as well.
This X9 2.2 10-Speed Crankset benefits from the development for XX, yet it delivers 2x10 performance and simplicity at 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.
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 Truvativ X9 BB30 2.2 10-Speed Crankset w/Bottom Bracket is Black with Grey accents and has a 175mm crankarm length. It's offered with either 26/39t or 28/42t chainring combinations. It comes with a BB30 bottom bracket bearing assembly.
