You ever hear stories about roadies who retire for years then train for a month and can win competitive crits? The saying is that it's because he/she "has thousands of miles in their legs".
Here's the proof that the phenomona is real. https://www.eurekalert.org/pub_relea...-mmd011719.php More details: https://www.frontiersin.org/articles...018.01887/full The old adage "use it or lose it" tells us: if you stop using your muscles, they'll shrink. Until recently, scientists thought this meant that nuclei - the cell control centers that build and maintain muscle fibers - are also lost to sloth. But according to a review published in Frontiers in Physiology, modern lab techniques now allow us to see that nuclei gained during training persist even when muscle cells shrink due to disuse or start to break down. These residual 'myonuclei' allow more and faster growth when muscles are retrained - suggesting that we can "bank" muscle growth potential in our teens to prevent frailty in old age. It also suggests that athletes who cheat and grow their muscles with steroids may go undetected. |

The way I understood it was that when we train, over months/years the body will create new blood vessels as needed to support the increased workloads. These don't go away when an athlete lowers the workload during retirement from training. They are still there. So, when the athlete takes up sport again...any sport...they just recruit the pathways already in place.
There are countless stories in various sports like this. I'm vaguely reminded of a female road racer or TT specialist that retired to start a family. When the children got to a certain age she started riding again and was making the podium at world class events within months. I wish I could recall her name. She's either American or Canadian. |

I thought you Carleton was referring to Kristen Armstrong.

Her story is a good one as well: https://en.wikipedia.org/wiki/Kristin_Armstrong

Prototypes? Team GB bars? Take Away: At every speed and on every rider type, narrow wins and more-narrow wins bigger. This is why I'm a fan of the 33cm Alpinas. They work! For me, my Kilo times in 33cm Alpinas matched or beat my Kilo times in aerobars. |
I imagine that Dolan included the 28cm bars in the test to show that their commercially-available 33cm bars (£159.99 / $200USD) are very close to the *Team GB bars that are (nearly) impossible to get.
*I'm assuming that the 28cm bars are Team GB bars. I can't think of any other bars that narrow. |

I wondered how long it would be until we'd start seeing bars like this, the technology has been around since before Rio to actually it but nobody bothered to.

Basically, the benefits of steroid use don't go away after atrophy. The muscles continue to be conditioned and can easily return to that form without the use of steroids in the future. I certainly feel like it comes back to me a lot faster than when I first started riding, and I was never that fast to begin with. |

For me, my Kilo times in 33cm Alpinas matched or beat my Kilo times in aerobars. Probably going to stick with my 36cm bars for now, but having used them for a year or two, I really wouldn't be opposed to trying 33-34cm bars. |

This is one of those situations where they visualized data badly, and by truncating the y-axis, do more to confuse than to clarify. That said, going from 38 to 33 has changes that range from 2.5% drag reduction to 4%. I could think of some better ways to show this... but the story is, that's a ton! And, if we assume that these are representative... more gains to be had with larger people (or rather, smaller people need to go narrower to see proportional gains).
Probably going to stick with my 36cm bars for now, but having used them for a year or two, I really wouldn't be opposed to trying 33-34cm bars. I totally agree about the visualizations. One should always include zero in comparisons like this. I completely overlooked that and looked at the numbers. |

Here's something interesting: all the German's run 3/32. And 9 or 10 speed shimano road chains.....

Efficiency because of less surface contact area? Or because 9/10 speed chains have better implemented tech to make the chains more efficient? I could see that Shimano and other chain producers focusing more on premium 10 speed chains compared to their 1/8tj offerings.

It's "free speed", I guess. |
11 speed DA chain is the efficiency weenies dream. It's unfortunate that not nearly as much effort goes into 1/8 chains (realistically there doesn't need to be other than from a pure efficiency standpoint, of course as things get narrower on road chains they have to keep working on them)
I'm surprised to see sprinters on them though, some of the stronger guys may be able to snap them. |
