Drop bars are known for providing additional hand positions when compared to the standard flat bar, but BP4 seems to be taking that notion to new heights (drops). While many companies are experimenting with different reach, bends, and sweeps, BP4 is adding another dimension to road handlebars – top drops. The admittedly strange looking handlebars drop down where a road bar would typically be flat. The resulting hand positions are claimed to be an improvement over standard bars in both aerodynamics, performance, and comfort.

Using a standard 31.8mm clamping surface, the aerobar compatible bars then drop 50mm on each side creating an additional hand position. We’re told that some riders use an additional +8 degree stem to compensate for the additional drop, while others are using the bars to drop down even further than their current positions. BP4 claims in their testing they have seen decreased drag, improved breathing, and higher power output with the bars in wind tunnel testing outlined here. In addition to the measurable improvements, BP4 states that rider comfort is greatly increased as well since the new position more closely mimics the arms’ natural position.
Patented in the U.S. and Europe, the bars will first be available in carbon only, though an aluminum version is in the works. Weighing in at 208g for the 42cm, Warbirds will be available in 42 and 44cm version initially with a 40cm and 46cm on the way. Currently the carbon bars are about 8 weeks out, with retail estimated at $395.
