The next logical evolution for bike company Kestrel has finally arrived in the form of the 2011 Kestrel 4000 Pro SL-Ultegra. The 4000 Pro SL-Ultegra looks very different from the standard Kestrel bikes we have come to know and love, especially with the addition of the seat tube, something that has never been done in the entire bike line from Kestrel, including its predecessor the Airfoil.

Because of the introduction of the seat tube in the Ultegra’s design, the bike’s ride has experienced an increase in stiffness all around. The bike frame gets bolstered thus increasing the responsiveness yet maintains the trademark smooth ride as a result of the thin seat tube. Several sizes are available but a word of warning, though: These bikes have a low geometry so this might fit perfectly for those guys who really want to hang low.

Simply put, this new tri-bike is boldly going where no bike has ever gone before. For one, we know that it now sports a seat tube unlike the previous bike models from Kestrel but also note that the components that are placed within the bike are truly heavy-duty stuff. What they are truly proud of is the number of Shimano Ultegra parts and kits that help make the Kestrel 4000 a running piece of artwork for riders and cycle enthusiasts.

At $4000 you get a whole lot of bells and whistles plus one truly awesome bike for whatever the occasion needs.
