Speedfil Aero Bundle

$90, Treefortbikes.com

The draw: Fast and easy refills

Speedfil lives up to its name with this unique BTA hydration system. The Aero Bundle starts with the Z4+ cage, which mounts easily to most bars using cable ties, and can sit in either the forward or reverse position depending on your preferred straw and Garmin-compatible computer mount locations. The second part of the “bundle,” the A2, threads atop the provided 21-ounce, BPA-free bottle, and features a refill port that achieves both rapid refills and a splash-free ride thanks to a clever yet simple sliding door. Bonus points for including a second drink tube and for an insulated sleeve that helps keep fluids relatively cool under the hot sun.
