do you mean worse in mileage?I see they offer silver too. If the Uberturbine vendors offered silver, I probably would have gotten one in silver and it would have saved a lot of work painting. That sport wheel design however seems a lot more open, so I wonder if the aero would be a bit worse than the Uberturbine or the Aeros.
few pages ago in this thread someone posted a video about the mileage.. it says that the uberturbine is alot better. You're right though that the sport wheel has more spaces in between.
Personally i don't see any difference between aeros and ubertubines.. and minor differences having just regular rims. (all 18's)
i'm kinda liking this new design, but they're a bit more expensive than the uberturbines edition. by $100 (the lower price ones have high shipping cost)
