EC90 Cranks (available fall 2008)

How do you make the best carbon crank in the world? Start by thoroughly testing every high-end crank currently available for ultimate strength, fatigue strength and stiffness. Then hand those numbers to a world class team of engineers and designers, with one simple goal: make a better one.

The result is the EC90 carbon road crank. At 558 grams, it packs the highest stiffness-to-weight ratio of any carbon crank currently available. It has also tested at over 500,000 cycles in a grueling fatigue test—five times longer than the nearest competitor. That’s almost unheard of in a carbon crank. (See comparison charts.)

To do this we started with our CNT Composite, the most advanced carbon fiber material in the bike industry today, and developed our own blend of foam core molding, bladder molding and compression molding to create a highly refined carbon structure, and a superior level of performance in a carbon crank. It doesn't get any better than this.
