I bought the speed V there along with 3 other things, all of which were at the lowest price i could find. The saddle was the only thing i bought that i wasn't sure if i got the lowest price because there are 2 other models with the same name and priced differently, and i'm not sure which one i got. But the price was as low as i've seen on any Speed V, so it's at least as good as anywhere if not better.
