BIKERUMOR.com 2009 SEA OTTER CLASSIC COVERAGE: Rotor was showing their prototype elliptical chainring crankset that’s being tested with the Cervelo Test Team.  The aluminum crank arms have three drillings running the lengths of the arms, two starting from the pedal side, one in the center from the spindle side.  The detail below shows the holes with a cutaway view, click to enlarge.  Their goal is light weight with rigidity that surpasses carbon fiber.

Rotor’s new SD-1 (Saddle 1) weighs in at a scant 136g and will retail for about 90€ to 100€.  It has hollow Ti rails, a Lorica cover and composite shell body.
