The results to that answer are right here in ST. Search is your friend.

Ps. Thanks again Kiley!

I think this project was inspired, and I hope that the Shootout 2.0 will happen some day

I wonder how the results would have been had each bike had to carry 2 bottles? The Ventum can carry 2 bottles of water in it's tank. Put a BTA bottle on the bikes and a BTS bottle and I wonder how different the results might be?

I wonder what the results would have been if the Ventum bottle was half its size... or if Kiley wore his watch on the other wrist... or if it had been a Thursday....

Well, I think it's a legitimate question. Thursdays are definitely slower though.

I won't speculate about the results, but I have to agree about Thursdays.

Considering a BTA in some instances can make the front more aero and a BTS is in dirty air I doubt too much.

That is shootout #2 (at least). Colby Pearce organized a similar effort in the mid-1990s.

In the white paper, the Ventum was tested without a BTA and the other bikes had a BTA.

The Premier Tactical used a Profile Design BTA and all of the other bikes had a regular water bottle

we're willing to do Shootout #2. You bring the bikes and a suitcase of unmarked 10s & 20s, we've got the expertise! Plus I've thought of 2-3 things that I'd do differently that would help shrink the standard error.

I suspect 99% of people have zero idea how many hours went into this before we ever arrived at the tunnel. It wouldn't surprise me if it was 10x the number of hours spent testing.

1 change on 1 bike often = a change on every bike to match things up.

One thing re: Ventum. The numbers we got in this test are the best wind tunnel numbers Ventum has ever gotten in a tunnel, at least up until this test.

I suspect part of that is bc Faster (RIP) where they tested was so narrow you got drag from the walls, so short that airflow didn't reform behind the bike at yaw and no real way of allowing or observing consistency in rider position run after run after run.

If there is anything I'm most proud of is this test had smaller error bars with a rider than some bike only or mannequin only testing from some of the largest players in the tri/tt bike market in some of the best known wind tunnels in the world.

If Shootout 2.0 happens again, can we go race each other at the go kart track?

I'm lining some stuff up for the tunnel the week of April 11-13th. I may have to hit that one of those evenings after wrapping up

That advantage of having a bigger bottle and not having to have say an extra nutrition bottle or the like works so much to their sponsored riders advantage over other bikes.

All I can say is that it rides really fast. By far the best tri bike I've ever owned (comparing to QR, Look, BMC, Trek, all that I've owned). It's just crazy comfortable and handles really well. I have no concern at all going really hard into a corner and still be able to stick the turn without any concern. It also allows me to accelerate out of the corners without flexing (I used to be a sprinter, so I still have some short burst power that tend to flex most frames).

Here's a real world, power-based test of a Ventum against an Orbea TT bike:

The results in this report show that the Ventum One is the fastest of the bicycles tested. When tested in race trim (with 1.4 liters of hydration), the Ventum One demonstrated significantly better aerodynamic performance (24% less drag) than the closest competing bicycle tested, the Cervelo P5.

A rider-off test where the cervelo has a bottle on the bars and the downtube?? That is an absurd comparison set up to be extremely biased towards the Ventum and not representative of the real world.

Put riders on, then a BTA and BTS bottle (or an aero bottle on the seat tube), a much more realistic comparison.
