This is the Kestrel Legend SL Ultegra Di2 Road Bike. At a mere 780 grams, the brand-new Kestrel Legend is the lightest frame The First Name in Carbon Fiber has ever produced. Made of ultra high-modulus carbon fiber with a remarkable weight-to-stiffness ratio, the Legend’s Kestrel EMS fork and H-stays provide compliance, comfort, and improve lateral stiffness; the proprietary tapered head tube enhances steering precision and front-end stiffness; and asymmetrical chainstays offset drivetrain-induced torque on the rear triangle.


  • Featherweight 780 grams – lightest frame Kestrel has ever produced
  • Ultra high-modulus and high-strength carbon fiber with ground-breaking weight-to-stiffness ratio
  • PU inner molds supply smoother inner walls, an increase in stiffness, better compaction, minimized wrinkles, and optimized resin content
  • EPS foam forming used in the manufacturing of the fork provides better layup in the crown area for improved compaction and resin content
  • Kestrel EMS fork and H-stays provide compliance, comfort, and improve lateral stiffness
  • Proprietary tapered head tube enhances steering precision and front-end stiffness
  • Asymmetrical chainstays offset drivetrain-induced torque on the rear triangle
  • Size-specific frame for each frame size. Larger frames use slightly larger diameter tubing for increased stiffness for larger riders.
  • Downtube and top tube wrap around the head tube for increased front-end stiffness, which aids in steering precision.
  • Shorter head tube for competition geometry and an aggressive riding position that pro-level competitors demand
  • BB30 is 18% stiffer than the RT-900; 1 1/8” – 1 ½” tapered head tube is 26% stiffer than the RT-900; frame is 22% lighter than the RT-900

Size Selection:
Bike size selection is a combination  of measurement, rider preference, and rider style.  The guide above is intended as a starting point, but it is recommended that you try out a few frame sizes in your range and pay attention to the frame size as well as the top tube length.  Top tube length is a key measurement to find the right size frame since geometry can differ from one model to another.

Kestrel Legend SL Ultegra Di2 Carbon Road Bike (Carbon/White) (48cm)
The bike is solid and stiff as advertise. It did take me long to fall in love with the bike. I also like the Di2 as well. Much better than the mechanical shifting and more responsive. Will see how it treats me over the year but so far so good. Special thanks to Justin and Mike at Cycle Sport and Amain, respectively, for putting together the bike and complimentary jersey with my purchase. It totally worth the drive up. Keep up the good work guys!
