highracer full fairings?

Is there any fairing besides the Mueller Windwrap XT that will fit a Volae Sport or Club, or a Bacchetta Strada or Corsa? The HPV Streamer claims a universal fit, but their photos show only smaller front wheels.

I can't answer that. Most highracers use tailboxes if they want an aero add-on.

Yes, I expect to use a Terracycle Tailsok or maybe the Lightning panniers in back. I was hoping to find something for the front too.

Although the lightning panniers will be more aero than regular panniers, I don't think they're going to be more aero than the naked bike. While I'm no expert, if you're interested in holding cargo and making your bike more aero then I think you should use an aero bag or hard shell cargo tailbox (with the smooth hard surface of the latter apparently being more aero than a taught fabric of the former, although soft ones are lighter and more easily removable from the bike). Manufacturers of soft tailboxes include Angletech Cycles, Radical Designs, and Bentupcycles and the only maker of aftermarket hard tailboxes I know of is Novosport (although of course you can always make your own).

Most people don't use a front fairing with a highracer. I'm not sure if that's because they don't provide much aero advantage for this format or if it's because the highracer crowd just isn't interested in fairings. Personally I don't use one because I believe the extra weight will make me slower on average; Since, in terms of average speed, it's physically more efficient to boost your bottom speed than your top speed my philosophy is to only make aero improvements when it doesn't incur a weight penalty. Moreover, I understand that most mounted fairings are somewhat fragile which I believe would create problems for me as my bike gets knocked around a lot (carried indoors, locked up, etc).

Not saying you shouldn't use one, just explaining why I don't. However, I'd be willing to try one if it were recommended by others. All I can say is that one of the advantages of the highracer format is that it's compatible with more of the latest upright technology, so maybe you'd get more bang for your buck from a set of disc wheels instead (or were you planning on a front fairing in addition to disc wheels)?

There are a couple of reasons why highracers and lowracers don't use front fairings.
First is vision. Due to the nature of lexan and other plastics being, shall we say less than optical quality, it's best to look *over* the fairing to see the road. Otherwise they cause a lot of eye strain. But high/lowracer riders look between their feet to see the road. Putting the fairing high enough to clear the feet and knees means putting the seat more upright - which negates the aerodynamic advantage of lying back. Second, air spilling over the rear edge of the fairing is 'dirty' and if it hits the rider it undoes all of the aero advantage of shaping it past the rider's feet. Third is weight. Due t the first two, you're adding weight for no advantage.

In the case of more 'upright' recumbents such as TourEasy, fairings can help with flat speed. Whether they help enough to make the bike faster overall despite the extra weight depends on how much climbing the rider typically does.

Interesting. I've got one of these waiting to be attached to my helmet for sun protection:


If kept all the way against the chest I wonder if it would keep a nice smooth air stream from the riders chest over the rear tailbox (like a recumbent TT aero helmet). If what you say is true using a partial fairing for the pedal box seems problematic.

I don't know how much difference it'd make, but the face shield might help a tiny bit if you keep it down all the way on your chest. Of course, if you flip it up it would make a good approximation of a parachute, with all of the force being transmitted through your neck.
