Haha, I’ve seen me take longer than that, nothing quite like that blind bit of panic when you fluff clipping in twice...

If they’re always going to rely on Ant+/Bluetooth then a track crank will always be unfit for purpose in my mind unless they do something different with the data. Perhaps a track specific PM as well as broadcasting on Ant+ as it does now should also be storing the data internally and start recording as soon as torque is applied so that torque and power can be analysed later.

That would be true for magnet-based Cadence sensors, but is it true for accelerometer-based cadence? I know some of the pedal-based PM's supposedly record 30+ readings per crank revolution, I don't see why they would need two revolutions to start recording power.

carleton

Yup. I recall seeing some custom power meters used by the British that were wired.

Wired is the way to go if you really care about scientific levels of data collection. Wireless is simply convenient and easy to install.

They may record 30+ times per revolution, but they need a time stamp in order to calculate elapsed time. I believe that time stamp is triggered every revolution. I don't know much about the accelerometer style. But, I'd like to know what is recording 30 times per revolution. Is it the head unit or the cranks? My guess is that they may be recording 30 times per revolution, but only transmitting the average of all 30 every revolution.

The way that many head units calculate cadence is that they receive torque readings every so often:

- 10NM @ 1:00:30
- 11NM @ 1:00:31
- 11NM @ 1:00:32
- 13NM @ 1:00:33

And then it says, "Thanks for the torque! I see that you (cranks) are sending me (head unit) torque every 1 second based on the elapsed time between each reading. I calculate your cadence to be 60RPM! From there I'll take that 60RPM and that torque and calculate your POWER!"

This calculation can be made after 2 readings and updates after every subsequent reading.

Ever wonder why some riders race international competition in their national team colors and other race for a pro team? Here's a good explanation why: https://www.beatcycling.club/en/blog...have-achieved/

SyntaxMonstr

Or because their home nations suck! (Not bitter at all that Pakistan screwed me over...)

It'd actually be really interesting if trade teams got to compete in Olympiad events or world championships. Like yeah, most of them are largely alt-teams for national squads, but you'd get a wider variety of representation from countries that might have promising athletes but no support or programmes in place to send them abroad otherwise.

Saw in my email today that Flo Cycling is going to start offering their 6 / 9 wheels in track configuration. Nice option at that price range.

On an aside... I ordered my front Walker Brothers disc at the end of December... and it still hasn't been shipped. They've had some growing pains/family issues, but we're far enough out now that I am beginning to whine online about it... unfortunate because I really like their discs.

Olympic Speed Skating.
I just saw the 1000m men's race winning time was just under 1m 8s - according to the commentator the guys in this event see 2-1/4 g. In cycling most g-forces are resisted by the saddle whereas in skating all the g-force goes though the legs.

It used to be that speed skating was a perfect winter training for track cyclists (e.e. Heiden, Young) - I do not hear that anymore.

Still its of crossover, at least in the Dutch team Laurine Van Riessen is a member of both the Dutch Olympic long track squad and the national sprint team.

Apparently this is the new Cervelo T5....not sure if any difference to the GB T5 that was used in Rio? The bars are Hope, nice to see them branching out into track parts - i love their kit for mountain biking.

It looks fast

It used to work well for me. I lived I Michigan and the only way to ride a bike was on the old Racermate trainer, which worked quite well. Training in the basement staring at a 12" black and white TV and looking outside through a one of those basement windows that were placed at ground level so that in winter the snow obscured half of the window was just not as much fun as speed skating. Since Milwaukee had to the on 400 meter track, and it was not yet covered over, most of my skating was done on frozen ponds. The tracks were typically 6 laps/mile, and racing was pack style; kind of a scratch race on ice. When watching the pack style race at the Olympics it really back great memories. For me, bike racing in the summer was skating training, not the other way around. Besides riding the bike, we also spend a lot of time in the gym (a guys garage or at the community center) or a field doing dry land efforts. One of the more memorable was when we did broad jumps up Mt. Trashmore in Midland. And yes, it was the pile of stuff left in the dump. In the middle of summer the bonus was that you became insensitized to various odors. Good Times! I still miss it.

Is there going to be a pursuit specific T5?
The pictures above one has an integrated cockpit and Kenny's has a more "normal" stem/bar.

queerpunk

I wondered about that, too - but maybe in the smaller sizes there's no real way to achieve that raised TT/dropped stem detail.

Godsight

I am counting a 66x14 combo on Laura's bike -__-

I am also of the opinion that smaller frame won't have the dropped stem/headtube junction for engineering reason. Laura Kenny is 5'4''/1.63m so on 48 or 51cm frame.
Meanwhile Katie Archibald is 5'10''/1.78m so probably on 56cm frame.

Also if people are willing to share the source for those pictures I would like to have them. I always love to see track tech on instagram, website or even facebook.

Probably just a training gear for big gear work.

pierrej

Sprint bike looks pretty cool as well, though this is a bit bigger than the two above

carleton

Looks dope.

Seat top area looks precious like it could snap. Didn’t someone break a new LOOK right there? Vogel maybe?

Looks long. I like it. Is available for retail sale?

rustymongrel

Custom order through Cervélo 25,000 GBP for frameset. Bars must be purchased seperately from British cycling.

Morelock

ahh yes, the ole "it's for sale, but only if you want to fund GBC's next project" tactic

I inquired about the CRUX helmet from 2012 olympics long ago... I was sure it was a joke when they emailed me the price.

carleton

lol

With all of the hype around nylon straps (us sprinters don't get many new things), it should be noted that the freshly minted Team Sprint World Champions all used "old school" NJS straps:

pierrej

Also interesting that the Ned's best sprint team doesn't include any of the Beat guys

carleton

Buschli (I butchered his name) rode in one of the rounds, so he got a jersey.

Interesting that Roy or Bos didn’t ride for sure. I wonder why.

Baby Puke

Hmm. Bos was always only doing the kilo, I think, but I read VDB was doing the TS so I'm wondering too.
