Um...

Speed1 = x = d/t1
t2 = (100-1.58)/100 X t1

Speed2 = d/t2

Speed change = (d/t1)/(d/t2) X 100 - 100
=t2/t1 X 100 - 100
=3600/3543 X 100 - 100
= 1.61%

Avanti have undersold!!!!!!!

Oh, that's about 52s.




And we haven't even started talking about how aerodynamic improvements affect slower and faster riders differently and the magnitude of the gain for a given ability depends on whether you express distance improvement, given time, or time improvement, given distance. (Talking about this would be giving marketing too much credit... they don't deserve that discussion from what they've provided.)

Bell, when they lauched their "Vortex" helmet years ago (which I'm wearing in my little avatar), they had similar blurb with pretty graphs 'n **** that "showed" how much faster their helmet was compared to others with the reference being a rider who could ride at 25mph for an hour with a standard road skullbucket.

I know it's physically impossible to go 50 something seconds faster and still ride an hour for the same distance but we 'get it'.... Or at least some of us do.

Would you drop $5,000 on a 1.something% improvement? No, probably not. Mention "this piece of kit will shave off 2 seconds per mile" and all of a sudden it's "wallet emptying, small mortgage" time.
