Heard that the 2019 World M45-49 Women's winner (in 500m?) has tested positive. It promotes the US rider into Gold, if the rumor is true. I can't find anything in English that confirms this.

That's cool looking.

Two cyclists were found positive to anti-doping at the World Masters Championships on track in Manchester on October 16th: the Argentine Adriana Perino, gold in the 500m, and the Australian Julie Barnett, world champion in pursuit and holder of the speed record in the age group 55-59 years.

The thing could be archived as the usual sad positivity of two over-fifties, but it is curious how both have been found positive to LGD-4033, a forbidden anabolic that serves to increase muscle mass (or recover the one that is lost with age) . At the same time, LGD-4033, also known as Ligandrol, is considered by USADA, the US anti-doping agency, a steroid commonly inserted illegally in some food supplements to make them effective, already found in the samples of several athletes in the last year.

On the other hand, Perino was also found positive at Meldonium, which rose to prominence three years ago thanks to the positive nature of tennis
player Maria Sharapova.

At the moment the two athletes are temporarily suspended.

And the same Argentine, Adriana Perino, took gold in the match sprints as well before being relegated for pushing her competitor off track....go to the 4:12 mark:

Eventual champ, Cami Kornely, suffered broken ribs and collapsed lung, spending a few weeks in a British hospital. But ultimately she ended up taking gold in all 3 events entered.

New Aus sprint bars should be on show today, "they're pretty weird" -the engineer

Odd sizes, big reach numbers

Some bits of these have been seen already, for "reasons"

World Cup in New Zealand
What happened to the US Women team pursuit? Both the US and Japan teams did not finish while competing with each other in the first round.

From what I understand, US was passing JP and one of the JP riders crossed into the US and a crash ensued.

I saw a Corima X wheel in use at the NZ World Cup.

I think Corina actually do a 3, 4, and 5 spoke front wheel. Lots of the five spokes are being used by sprinters at the moment

I watched the 2019 Masters stuff while I was on the trainer last night. Some of those 50-54 guys are really fast. 34.5s 500m.

One thing I noticed is that almost none of them used aero bars. They used drop bars instead. This was indoors, so front disc, and presumably less wind. I wonder if outdoors, with wind, maybe a multispoke front wheel?, if more racers would use aero bars.

I've noticed that, for at least sprint events, that the top master's performances match that of top Elite Women.

lol I'm been preaching that for years. I'm glad to see people using narrow drops for the 500M with success.

I think the benefits of using narrow drops even extends to the 750M...and maybe even Kilo for some riders.

taras0000 12-08-19 03:10 PM

In that pic it looks as if the spokes aren't perfectly perpendicular to each other. Almost as if the intention was to make a 6 spoke wheel, but 2 opposing spokes were eliminated.

At Worlds, the next two age groups up were actually even faster. Aussies Geoff Stoker (34.046) winning gold in the 55-59 while Gary Mandy (33.942) took the top step in the 60-64 ranks. I believe Stoker ages up next year so both will be battling it out in the 60-64's.

That's amazing.

I wish the 500M were still run as an Elite Men's event. Even as an optional event. It's not about male or female. It really is a different event from the Kilo.

Aerobars only really help in the kilo to hold speed and not drop off too much. 500 isn't really long enough for aerobars to help, they probably are more of a hindrance with the compromised start position and swapping to the skis. Pretty sure most of the elite women are using drops for the time trial.

Double disc would be standard for all timed sprint events unless it was outside and real windy.

I think at the beginner and intermediate ranks (most national masters would be considered 'intermediate'), narrow drops would be on par or better than using aerobars.

It takes A LOT of training at speed to be very comfortable in aerobars at near 60kph/35mph. Including training on them behind a motor. Very few people train like that in aerobars.

Even though aerobars are theoretically faster, it takes a lot to avoid the downsides of using them when compared to narrow drops. Those downsides are:
- Letting off the gas when transitioning from bullhorns to skis
- Not being comfortable at high speeds in them, thus subconsciously holding back some.
- Not holding a great line due to bumps in the track and/or lack of nerve getting close to the transition to the apron while in aerobars.

I'd imagine that Elite and Elite-fast Masters Kilo riders will have all of the above figured out.

"Russia banned from Olympics, world champs for 4 years; athletes could compete as neutrals"


Russia is banned from the next two Olympics and other major sports events for four years, though its athletes could still compete without representing the country if cleared by anti-doping authorities.

Russia’s hosting of world championships in Olympic sports also face being stripped after the World Anti-Doping Agency executive committee approved a full slate of recommended sanctions for tampering with a Moscow laboratory database.

Russian athletes will be allowed to compete in major events — including world championships — only if they are not implicated in positive doping tests or their data was not manipulated, according to the WADA ruling. “In this circumstance, they may not represent the Russian Federation,” according to a WADA release.

taras0000 12-09-19 06:30 PM

Allowing athletes to compete as neutrals defeats the premise of athletes being accountable to their country, and a country being accountable to its athletes. The athletes and the federation are the same entity. Without a federation, the athletes can't compete. Without athletes, there is no federation.

This is no deterrent to the corruption. It just puts it on hold for 4 years. In the meantime it allows the state to hone it's doping program on athletes who aren't allowed to compete.

In 5 years it will be business as usual for them.

You stop this by making it so the clean athletes see it as too risky to compete for dirty federations. Barr them as well and they will seek other federations to compete for.

Anyone ever see these before in the wild? Flexible valve stem/extender for disc wheels. Anyone know who makes it?

If that can take 200 psi that's a ridiculously obvious yet awesome idea

wow forgot these ever existed. Corima used to make them, although I don't think they do any longer.
