I ride Ultras (typically 12 hours, sometime solo and sometimes 2-man relay style). The AeroJacket was the perfect solution. I bought a Mavic Ksyrium Elite used and placed the Aerojacket on it.
It's a great solution for ultras because the spoked wheel offers more comfort over long distances than a carbon disk, yet I get the benefit of aero during the entirety of the race. Personal A/B testing (real world, not lab) has shown coupling the Aerojacket with a tight fitting kit and arrow helmet allows me often squeeze out 1.8-2 mph more over the course of the race than a non-aero set-up. (Regular helmet, spoked wheels, looser training kit).
Admittedly, at 235lbs, I am not your conventional road rider. As a result I have had my share of problems with wheels, broken spokes, challenges with keeping wheels true (necessitated purchaseing a Park truing stand to maintain my wheels) and have even managed to snap an axle on my road bike over the years. In search of a solution, I contacted Wheelbuilder three years ago to build a set of wheels to accommodate my weight. Wheelbuilders's recommended RR585 wheels, 350 hubs, and laced with thirty-two spokes front and rear. Fast forward three years later and the wheels are as solid, have performed flawlessly and have not required a single truing. My compliments to Wheelbuilder for constructing a great set of wheels and carrying me with confidence over the years. I look forward to many more enjoyable miles on this set of wheels.
