No buckles. [/thread]

No it's definitely not just that, as I've seen the empires beat out the bonts with no straps by 3-5w.

Which Bolts? The ones with the big rubber bumpers on the front? Cronos put Empires to shame.

Not from what I've seen.

Actual numbers? There's a reason all the Drag2Zero boys are using Cronos. DMT Pistas abd Spec Sub 6 are fast too, but again it's too do with the lack of buckles and covered laces.

You will haven't said which Bonts you saw them tested against.

wouldn't any laced shoe with smooth exterior surface do the same thing?

Pretty much. Cronos are the exception and banned as a result.

I still think that's really stupid they banned the Cronos. We can wear pointy helmets but not pointy shoes? Lol

I have a theory. But want to do more testing to test it out.

Which bonts are we talking about here? The Chrono?

Yes it was the cronos,
They may be slick and pointy, but the empire is not only narrower but generally there is less space between the inside edge and the crank (resulting in lower stance width, which is more aero)

I don't believe this for a second. That would make Empires over 10w faster than a standard shoe. What was the protocol and where was the testing done?

Hello Thomas Gerlach and All,

I have both Bont Zero + and Giro Empire.

I have many miles on the Bonts and they are super comfortable.

I just recently got the Empires on a sale and do not have much time with them so far but they seem to fit well.

The Empires are visibly a bit more narrow than the Bonts and appear that they would be very aero.

Size 46 Bonts with SpeedPlay Zero cleats and View-Speed modification for running are 106mm wide and weigh 307 g.

Size 46 Giro with SpeedPlay Zero cleats and View-Speed modification for running are 99mm wide and weigh 303 g.

Cheers, Neal

+1 mph Faster

Those seem pretty heavy. Did you get the Empire SLX or ACC?

Are you referring to my test? If so it was at A2. No specific protocol, I didn't go to just test the shoes, it was one of the last items tested. I will say if you look at my bike splits, the only major change I have really made was the shoes and aero kit. My splits this year are significantly faster on similar watts.

Maybe your drafting or motorcade doping. Seems too good to be true to me


I seriously hope you sense the sarcasm here. I am not accusing you of cheating

The irony is that when I finally have a front pack swim it will all be sorted out by then and no advantage will be present any longer.

Haha,
I bet thanks because you own bonts and don't want to believe it.
Testing was done at a very very reputable tunnel.

Actually I have Empires and all my velodrome testing certainly doesn't suggest they're that fast.

Then you might need to go for decent testing at a tunnel

What did you test them against? What aero kit did you change? Surely your visit to the tunnel showed you the drop in CdA with each change of kit. Also, comparing splits on different races on different days is no way a scientific test.

My 'eye' wind tunnel says DMT pistas look plenty fast? The giros look slender but pretty round and blunt fronted.
Someone needs to make a crono shaped shoes for the tri market screw the UCI

Pistas are 4.5w faster than the Vaypor+.

I can believe that Empires are faster than the Zero+ (mainly because that giant plastic bumper doesn't help), but not more than Cronos. I'll happily buy anyone's pair of Cronos to test and report back the results.
