Taking its cues from the ultra-aggressive Vortex, the 2007 Siena sports a racing geometry that is agile and responsive. But wait, there's more! The Siena features many tube shapes and technologies from other high end Litespeed models as well.

  • The top tube is based on structural dynamics of the ultralight Ghisallo and is super-strong featuring GET2 butted tubeset.
  • The tube shapes at the head tube junction work together to create a rigid front-end for stable performance and confident tracking.
  • The oversized expanded-diamond down tube is crafted from 3Al/2.5V titanium alloy and is shaped for superior stiffness and handling precision.
  • The oversized seat tube further enhances the overall frame stiffness by locking the bottom bracket in place.
