The very first Wedgies were made of wood.  Yes seriously.

The wooden prototypes turned into fiberglass for field testing, then ultimately carbon fiber for production.

But, of course, we kept searching for ways to improve. We found the storage compartment did not need to be carbon fiber, in fact plastic works better because it makes the Wedgie easier to open and close and wind tunnel testing confirmed it’s every bit as aerodynamic. The switch to plastic reduced manufacturing costs and we’re passing on the cost savings to our customers.

- Wind tunnel testing confirms that it’s every bit as aerodynamic
- Real world testing confirms that it’s more convenient
- It’s still incredibly light (the switch to plastic only added 28 grams)

And with it new price, it is the value leader in aero savings (14.4 average watts savings for $99.95 = $6.94 per watt)
