Venge Vias disc, first photos?
Moderator: robbosmans
I´m almost sure that we won´t see the Vias on cobbles during next few weekends. Those photos having cobbled road on backround is just a big joke. It will be Tarmac with 30mm tyres.
OK, if there will be couple Viases, they will be changed very quicly, just like Sky changed their Dogmas with "rear suspension" during last years P-R.

I've always had this haunting feeling that the Win Tunnel sort of shows,whatever Specialized wants it to show... But I have absolutely nothing that backs that up, I just carry around that feeling...
Anyone with some insight, know-how, white papers or otherwise? Is this thing really trustworthy?
I haven't found anything. As almost always in the bike industry the lack of data is deceiving.

I agree. Given there is no motion blur of the spokes, I think it's staged.

Excellent call.
It appears to be 24h 2x on the left and radial on the right.

Definitely generating some good buzz, though.
Ya think?
There's so much buzz around here I need a beekeeper's suit.

Yeah, I was thinking that for a bike that nobody cares about, an awful lot of people seem to care.

As for the wheels. The disc version of their new Roval 64 wheels (f wheel is 24h 2x disc, radial non-disc) were released with the rim brake VIAS. If that didn't make it obvious a disc version was coming... Rumor is the VIAS was actually designed around discs originally but UCI dragged its feet on legalization so Spec held off on its the release. I fully expect it to be as fast if not faster than the rim brake version. Look for more aero disc bikes with impressive windtunnel results to be released this year and next.

While not a technical paper, Tom Anhalt has pretty extensively audited the tunnel through some of his own testing with wheels/tires. The results seem pretty consistent and exactly what you'd expect the drag charts to look like.

I'd be more concerned with test protocol skewing the data rather than the tunnel being inconsistent. Take the disc vs. rim brake test they did, the cabling introduces a big as to its effect on the data, but it's for the Win Tunnel series, so I guess we can't be too picky . I hope we'll get better data if they announce a disc Vias, a more apples to apples comparison.

Would be nice to see new (third party) wind tunnel tests if this eventually comes out.
Whatever the result, I would never purchase this.
Still defeats the purpose and it only makes a weird-looking bike even more weird-looking.

I think you've heard similar things, my friend. Soon we will learn the accuracy of the rumors.
I'm intrigued to know how they're going to put a legal fairing over the rotors.
