we should detension and add weight to our wheels then?
Yes. Loosen all spokes. This makes the ride so smooth that you will automatically be .0875464723 MPH faster just from being fresher. Scientists have proven this with lots of calculations and stuff.
Add lead strips to the rim. This increases the flywheel effect, again making you much faster. You even climb better too. It's scientifically proven. There's lots of numbers to prove it.
Also, deep section aero rims ride just like light, box section tubular rims. Not even scientists can tell the difference.
Those fan blades will absolutely make you faster. Scientists have proven these blades break up the boundary layer of air better than trip strips and improve cooling in the region of the rider's helmet. The net gain in wattage for most grandmothers is 12.8506025 watts (based on 56 kg grandmothers in a double-blind study).
Seriously, 32 spoke, 3x box tubulars, lots of glue and a good pair of CX/CG tires will get a guy around most crit courses and be easily replaceable after that inevitable stack-up.
