I did a short test ride on the "black" GS Aero at John's on Saturday... VEERRRRYYYY interesting machine. They've done some very nice design work on this trike for aerodynamic profile. The "airfoil" crossmember is nice, and they've even shaped the derailleur post, except for an inch or so where the DR clamp goes -- so, there aren't very many options for putting lights, etc. on the front.
The steering is accomplished by pushing/tilting the grips backwards/forwards, and this thing turns on a literal dime -- it has a REALLY tight turning radius. Perhaps this is why they designed it with several degrees of camber on the wheel orientation. The steering linkage is pretty innovative, and aerodynamically minimal. The brakes are specially designed drum brakes that are mostly enclosed by the wheel covers, further improving the aero profile.
At a 20 degree seat recline, a headrest is practially mandatory, but it's a very comfortable ride. The 1.5" (?) Scorcher tires roll nicely, and can soak up some of the road roughness. Front triple has a 56T stock big ring, to compensate for the 20" rear wheel. I didn't have the opportunity to take it up to full speed on a flat (or downhill), but I could imagine easily getting this trike up above 30mph top end, vs. the ~28mph max I'm usually getting on my SprintX -- granted, I've got suspension, indirect steering parts, and disc brakes hanging out there in the airflow.
This machine is definitely designed for speed -- you're not going to be putting racks/panniers on this beast, and you're going to feel the bumps -- this is for hauling ass on decent quality roads. But, DAYUM, it's nice... although you might need some help getting out of it due to the low seat and 20 degree angle...
Test ride at your own risk!
