CRANKSET: Truvativ
TruVativ is a leader in high performance cranksets. We use several different TruVativ cranksets, most featuring the ISIS Drive splined interface. The ISIS system boosts crank/bottom bracket interface stiffness by 25%-30%, increases impact resistance by 100%, and improves fatigue resistance by 300%. The Elita crankset is a road design that is exceptionally stiff, yet still lighter than Shimano's Ultegra Hollowtech crankset. TruVativ assemble the Elita for us with custom over-size chainrings. The stock Firex SL crankset that we use on our Zero G is strong, durable and light.
