It would be hard to get Loggins & Messina out to the Superdrome to play in the infield for instance , but other community park type events would be possible to work in around the riding schedules

A BMX track would even fit comfortably in the infield of a lot of tracks ---- would serve the purpose of introducing young people to our sport, --- and dads and moms too nervous to bust out double jumps may feel more comfortable trying their hand on the boards as well

Milton has two (maybe three?) basketball courts in the infield that get used for badminton and volleyball as well. Seems to to work.

Yeah, a multi-use facility seems to be the best model. LA has a gym and (I think) movable volleyball courts in the infield.

I think if it's planned as a multi-use facility from the beginning with a clear plan on how that would work as well as protect the surface of the track, then it could work.

This is Track and Field (Athletics).


More than 30 Russian athletes participating in Siberian Indoor Championships last weekend abruptly withdrew from competition when drug testers arrived at the event.

According to the Russian sports website Championat, as many as 36 athletes cited various illnesses for withdrawing from the competition at the city of Irkutsk.
https://www.npr.org/sections/thetwo-...testers-arrive


This is getting weird:


In 2016, one Russian athlete tried to bribe a drug tester and another ran out of the stadium during her own race to avoid being tested, the World Anti-Doping Agency says.
But, it's being handled internally, so nothing to worry about:


The Russian track and field federation "has started an internal investigation" into the incident,
:D

Are the Aus sprinters on Ultras as well? I was considering picking up a BT but couldn't decide between the Edge and Ultra. What do you think of the dropouts on the Ultra?

I think they switch between them for different events, looks like the ultras are used for timed events more than the edge where they'd probably want the slightly faster frame aerodynamically.
More traditional than the edges so might be easier to source but I'm sure both are more than adequate. If you're undecided maybe ask BT for a geo chart as I think there are subtle differences between the two, one being pursuit oriented and the other sprint.

Two adjacent chain connectors? Perhaps it is to accommodate different gear ratios. I have that problem but use different chains.

I believe this is the company that made the cranks for the Team GB bikes. I posted about them a few months ago.

Yes. It's a common way to make a "short chain" and "long chain" out of a single chain.

Had not seen that either, a neat trick & with a waxed chain would be a nice clean/quick change.

Xiaofei Wang (CHN) uses double straps in bunch races.

This photo is from the World Cup Santiago stage Omnium Scratch:

https://i.imgur.com/N7BxahN.jpg

I found a blurry photo of her wearing them in the Omnium Scratch race this weekend as well: EDIT: Apparently BF doesn't like twitter links. Try this: twitter: /uci_track/status/954669678118436864

I'm still waiting for more enduros to catch on to this idea :D

Wang finished 7th in the Omnium for this event and 5th in standings across all World Cup events.

taras0000 01-22-18 05:08 PM

I wonder if this is because she is from China. Their first successes in track cycling (or even cycling in general) came from their female sprint squad. In other words, this worked for the lady sprinters so it must be good, therefore trickled down/across to an enduro. Track cycling being a relatively young sport amongst the Chinese, there would be very few ties to traditional methods, especially the way the government was throwing money at the federation with the mandate of "whatever works".

Yeah, maybe so. Maybe simply a fresh and empirical approach? A woman of her stature should have no problem staying in a set of pedals with the tension properly adjusted. My guess is that it's for another reason.

Straps aren't just about preventing unclipping.

I don't think that every enduro should use straps. But, I'm fairly certain that some will benefit from it.

It's interresting that the 2 world class enduros that I've noticed doing this were both women. I would think that the stronger men would do this first.

Baby Puke 01-22-18 06:33 PM

Speaking of straps, I notice Theo Bos is one of the last top pros to still use the Japanese-type straps. Curious what pedals he's using with it, anybody got a good photo? I've been unable to find anything.

So is his teammate Buschli, who was using the orange nylon straps that the Dutch team uses then seems to have switched back to NJS in the past 6 months or so. Van Den Berg uses nylon BLS straps. I think he's sponsored by BLS.

2 of 3 are on NJS straps and all 3 seem to be on Shimano pedals. Looks like Dura Ace. I think they all run red zero float cleats.

Do you have some evidence suggesting this is an empirical decision? Because that is a BIG assumption. The more I hear about elite athletes, and professional riders, the less inclined I am to think they have ANY reason or logic to the things they do, or equipment they use. Remember the link to the Zipp testing?

I don't mean the tone of that to be super confrontational, but I am skeptical at best.

I remember someone had some data suggesting massive increases in watts "just from using straps" but as I recall, wasn't that for standing starts? Do we have any pursuit data with straps vs not straps? Or any data from flying efforts (which would, hypothetically, negate the increased watts in a start) with straps vs not?

Personally, I would never be able to get the strap tension right. If they were loose enough to be comfortable for 20+ minutes, they wouldn't do any good, and conversely if they were tight enough to do anything, they wouldn't be comfortable to ride!

carleton 01-22-18 10:19 PM

Denis Dmitriev (RUS) seems to go back and forth between NJS and nylon:

Sandie Clair (FRA) uses doubles:
https://i.imgur.com/T8VLFQy.jpg

Förstemann (GER) uses doubles:
https://i.imgur.com/XbkJajt.jpg

There seems to be a 60/40 or 70/30 nylon/NJS split among sprinters. The NJS straps are a really, really mature product. The clasp is an engineering marvel.

Also, I have weighed them all:

1 BLS strap: 32g
1 single Toshi NJS strap: 31g
1 double Toshi NJS strap: 67g

taras0000 01-22-18 10:27 PM

From the looks of Bos' pedals, currently it seems like 3 hole Dura-Ace. He was running SPD-R on his track bikes up until December '15.

Sorry, no I don't. I shouldn't have stated it that way. I should have written, "maybe" with a question mark. You are right, it could be superstition.

This would be very easy to test.

My only evidence is anecdotal and what I see in photos. And the few people I can convince to try it.

I convinced Oscar Clark to try using double my double straps (attached to Speedplays at the time) at 2009 collegiate track nationals for his IP. I included his kilo times as well to offer more data as to how he was riding.

Oscar Clark (of BMC/Hincapie)
https://legacy.usacycling.org/results/?compid=221975

2009 (Trexertown): 4:51.7 pursuit (using straps) / 1:13 kilo
2010 (Major Taylor): 4:52.7 pursuit / 1:12 kilo
2011 (Major Taylor): 5:01.4 pursuit / 1:13 kilo

In 2009 He placed 3rd to two other future pros, David Williams (now of Astellas) and Joey Roskoff (now of BMC). He said he really liked them :D ...but I don't think he ever bought a pair of his own :(

I know I'm grasping at straws here. But, I truly think something is there.

Straps can be frustrating at times. One reason many people prefer laceup shoes with straps is because normal cycling shoes with 2 velcro straps (or a BOA disc) on the lower part of the foot can guide the strap into an uncomfortable spot between the two velcro straps causing pinching. This is worse with double straps.

I think that Bos is running SPD-SL.

Bos may have switched over to SPD-SL.
