After 800 miles or so behind a VStream Sport windshield ($179.95 from _www.nationalcycle.com_), the quest for more efficient wind protection is pretty much over. National Cycle makes two taller versions that are probably worth a try—especially when installation is such a piece of cake. At 17.5 inches tall, their shortest screen—2.5 inches shorter than stock, but 1.5 inches wider—punches a cleaner, quieter hole in the wind than anything I've tried yet. Since I'm looking over instead of through it, even at the top of the standard adjustment range, the dark tint hasn't been a problem. That uppermost position provides clean, quiet, collar-high protection from hostile wind and weather. There's no buffeting, and National's 4.5mm-thick, hard-coated Lexan is far more scratch-resistant than stock. What more could I want? Come to think of it, there's a decent chance something larger could make extended two-up travel more comfortable for Mrs. Carrithers, so I'll be giving the sport-touring version a go: stock 19.5-inch height, but 2.5 inches wider.
