I would certainly be interested and I have done testing at the Springs before on my TT bike (I don’t have a long background in track cycling). Rockdude would also be a good choice and has a more extensive track background.

Thanks Mike. Velodrome experience is really important for sensitivity testing. Really looking for someone who has done quite a bit of pursuit riding.

I'm up in Highlands Ranch. I've done extensive TT riding but it's been a couple years since I've been on the track. Happy to swing down there if you end up needing more subjects.

Hey Jim,

I have done year of velodrome riding as a junior and would be interested in helping out with your test. I currently live up in Littleton.

Just sent this thread link to a friend who lives in the area and has done a lot of pursuiting.

Great, thanks!

Hi Jim

Longtime Slowtwitcher and Track Rider here. Cathy sent me the link to this post.

I've been riding down in COS for a long time, decades. Many Track Nationals, and Masters Worlds under my belt. I have had 4 hour record attempts. My success ration is 1/4. Ive been to Aguas 3 times with the most recent trip being the season before last in Aguas, when I ran the trip for 13 athletes. And while it has not been announce yet, I'm starting prep for another attempt in 2024.

While I don't live in the Springs, I'm up in the denver area, and can devote as much time as you need since I'm retired !

In addition, I have several hours of wind tunnel experience from 3 years ago when I went to A2 and worked with Brian.

I also have all frames(s), wheels(2), helmets(s), skin suits(s), etc(s) that you would ever want to put a matrix together. Ive got two SRM's - one on the pursuit frame and one on the mass start frame.

I would love to help be a aero-guinea pig for you !

Wow Dave, you sound like the right guy for the task!
I'll PM you as we learn more about timing etc.
Cheers,
Jim

Thanks Jim,

I'll look forward to it and would really enjoy working with you

From my experiences with a proprietary “live” velodrome aero testing system like the Alphamantis / Garmin TAS system and having used this TrackTest++ system extensively over the last decade, experienced track riders are not necessarily the test subjects producing the most consistent results. Also, I think a 333m track should be “easy” J.

The least variation of CdA from half round to half round of down to +/- 0.0005 m² at a 200m track is produced by people having a rock-solid position i.e., don’t move on the bike, but still be able to stay relaxed and do not alter speed. As soon as people over pace the CdA variance increases. Sometimes even a triathlete was a “good” test person. But I also had top professional triathletes unable to hold the black line and varying speed almost like crazy.

Oh man, if you were just a little closer.
I ride a 166 meter track 2-3 days a week (Detroit)

I am up for it. I am a hour record holder, 1k record holder have three national titles on the pursuit or TT bike. Most importantly, I have conducted aero testing on myself and others in that velodrome and other velodromes around the world, so I know and understand the process. I could bring my weather station and equipment and we could compare your results to my results as a check on the data sets. Let me know, if interested.

Best of luck!

Do a delta mass test. That should let you assess sensitivity to changes in drag, which will help you figure out variability in aero drag vs. variability in total drag.

I'm willing to help.

Looked through my old alphamantis testing data. Varied +/-2m farthest to shortest lap.

Willing to help. have tons of wind tunnel and alphamantis data on myself for you to look through if you want. Although the alphamantis data is more stochastic
