The Truvativ X.9 2.2 10 speed cranket features hollow forged AL crank arms for lightweight and super stiff durability. The X-Glide 2x10 shifting technology gives the user buttery smooth shifts that will go unnoticed. X-Glide is the common denominator that gives 2X10 unmatched shifting performance. Four identical upshift locations, ready to be be picked up by any outer link. Result? Perfect timing, almost instaneous shifts, up or down, even under load.
GXP is different and better. Other systems rely on side-loaded bearings to eliminate play, causing bearing wear. GXP captures the left-side bearing between the spindle and the left crankarm and allows the drive-side bearing to float axially on the spindle. There's no need to side-load bearings during adjustment. No excess wear. And a much simpler installation. Just tighten to the proper specifications and you're ready to roll, worry-free. GXP's two bicycle-specific cartridge bearings and eight seals ensure a smooth, long-lasting ride. The new Gutter seal system takes a two stage approach in directing contaminates away from the bearings providing longer bearing life. GXP's new Gutter Seal design also reduces friction, 35 percent less drag than the current GXP BB, improving rider feel and performance. Gutter seal system has deeper installation tool grooves which provide stability and support while applying torque to the adapter cups. The new design and material choice has dropped 15g out of GXP BBs.
