This is the case because Argon only have a pursuit bike, no other options for the fast(er) people, yet.

and there is a rule of thumb that one degree change in STA or HTA equals one centimetre of reach, so that would (artificially) add to the reach number listed. Also, with a slacker seat tube angle, as the saddle goes up, compared to a bike with a steeper STA, your saddle gets further away from the bars by comparison so that helps lengthen the bike too - they are things that don't really show up on the frame's dimension drawings.
Fair enough - I thought it would be ok as looking at the Argon 18 Electron Pro frame that Glaetzer is riding at the moment, that has 76 degree seat tube and 72.7 head tube, so i assumed this would be workable as its "similar".
What do you think about the geometry angles of the Look 875 Maddison? I expect its more tuned for endurance track riding but i would primarily be using it for Sprinting? My current Planet X Track Pro is too short in reach for me to get into a long & low aero position for sprinting.

The problem that I saw with larger bikes in general, road and track, was that frame specifics like layup and tube profiles didn't change from the small through to the big boppers. That made for some less than stiff big size bikes. That concern pushed me away from a lot of brands, but some notable exceptions that I ended up putting money down on are Felt, Canyon and my Duratec track bike. Duratec know their stuff and changed tube profiles and thickness to give me what I wanted - the biggest frame they had made that wasn't a tandem and stiff enough to make a wannabe sprinting giant happy. I was hesitant steering away from carbon, but super happy in the end

Kaben, check out a Dolan DF4 (or DF3). They are pretty long, low, and affordable. Yes, there are some known issues - some have seat post slippage, but if you torque to spec (17-19nm) it's not a huge issue. And yes, the dropouts are short on the newer version.

have been looking at the fifty point one custom frames but the geo chart for the size 23 which gives me that long reach has some very strange numbers in it - the seat tube is absolutely colossal at 716mm for example and the stack is also massive at 600mm. It doesn’t sound right and I can’t picture it in my head.

This reminds me of when I used to be a photographer and did a photoshoot with Jake Rupp. He was a veteran skater by that time. Kinda on the older side, but still had a top tier sponsorship (Element). This was about 2003 or 2004 I'd guess.
We were out in Baltimore shooting some non-commissioned work on speculation to send out to the magazines. Basically, unpaid work hoping that a magazine would publish them and/or a sponsor would buy them. I'd make a few bucks and he fulfills his obligations to his sponsors by staying in the media with hot photos/videos.
[Jake, tired and winded from skating hard] "You know why I do this, Carleton? Why I'm skating with you on a beautiful Sunday afternoon when I could be chillin' with my lady on the sofa?
[Carleton, changing lenses] "No. Why?"
[Jake] "The kids."
[Carleton] "?"
[Jake] "The kids are good. I go skate with them when I travel and they are ******** goooood. No joke."
[Carleton] "Ha." (ok?)
[Jake, introspectively] "They want my job, man. They want this job. And they'll get it if I don't work hard. That's why I do this." [drops skateboard and kicks off for another try at the trick...]

I just read that and thought of Pervis. I watched the Milton and Paris world cups online and it was sad to see him as pack fodder. He hasn't really slowed at all, the young'uns are really just that fast.

People are doing sea level 9.5s and at one of the world cups a 9.8 was the qualfiqualifi cutoff, they're definitely getting faster

There's definitely a changing of the guard happening. Kenny didn't make it past 8th finals I think? Where is Bauge? Dmitrev? The Germans? The Dutch are on a tear, and except for Bos (obviously) they are pretty young dudes. Looks similar on the ladies side.

Dixie Flyer is running a sale on theirs newish track handlebars. I'm looking forward to trying 'em.

The Dutch Sprinters seem to be doing what British Cycling did several years ago. They are coming out of nowhere and starting to win...and win...and win big...and win bigger..,systematically. We later learned that Team GB did a lot of things:
- Embraced using power meters and analyzed the data.
- Hired a team Sports Psychologist.
- Early-adopted using narrow bars (outside of Japan).
- Wind tunnel testing...of everything.
- Spent a lot of money on the track program because it offered the most opportunities for Olympic Medals, something like 5 men's and 5 women's) of all sports. Maybe only Swimming offers more. So, from a program standpoint, it was seen as a great investment because there were so many shots at medals.
Anywho...
What are the Dutch doing? Because it seems like their entire system is working for their riders.

Our situation is a funny one because at the elite end of town our track cycling is going pretty well, but the grassroots are definitely not possibly as a result of the HPU being the near sole reason CA gets Gov funding. It'll be sort of cool having a wind tunnel 5 minutes from my house, but not being on a national team I'll never get to use it 🤔

It was mentioned in the BBC World Cup commentary at the weekend that anything that is to be used at the next Olympics has to be used at an event before the end of this current season, apparently it’s a new UCI rule. Argon 18 need to get a move on with their new sprint frame.

Taking very good bmx and speed skaters and putting them on bicycles, that and riding is pretty popular over there.

"*While ANT+ can transmit data 4x per second, and Bluetooth SMART 64x per second, current power meters aren’t running this fast. Why? It would be too hard on the battery. Most power meters record data closer to once per second. This way, the head unit can essentially enter sleep mode for very brief periods of time, thus prolonging battery life."

I used to use cycleops speed/cadence bluetooth sensor on my bike to check my speed and cadence using my smartphone.
In my memory, bluetooth(smartphone) data refresh rate was faster than SRM PC7(records 2 per second).
Why don't track sprinters just use bluetooth system to record their data.
Or am I wrong with bluetooth data refresh rate?
Basically, if we have an app that records data 2 per second or more and able to download the data to view in Goldencheetah, that will be best bike computer for track cyclists.
BTW bluetooth sensor I used had trouble reading high cadence, but I could be because of the app.

You can send 64 readings per second to the head unit, but if the head unit only aggregates the data into 1 second blocks and records that average, then that's all you get to see in the file when you download it.
So, it depends on the head unit more than the sensor.
For example, the Garmin 500 and SRM PowerControl 7 are both ANT+ head units. Using the same speed and cadence sensors, I can send data to both the Garmin and SRM head units. Garmin will record the average of data recorded every second, the SRM every 0.5 seconds.

I am going to look for iphone app that records more than Garmin and see how it works.
