Seeing as people are still commenting on the April thread, I thought I'd make this months one.
Apparently there's some kind of big bike race this month  |

Amgen Tour of California, yeah...
It's pretty big, especially in the USA I think...
Wow, 4 May, and there still was no May thread? Very surprising...

Apparently the Giro is a good time to get into tweeting according to Cavendish
(closest i could get to news without actually being news)

So here is some real news. There is a legal battle going on at the moment regarding the Kimmage defence fund which was set up at the end of last year when he was going to be sued by Verbruggen and McQuaid. It resulted in over $90,000 raised from small internet donors. They dropped the suit against him but in turn Kimmage launched a criminal complaint against both of them, which has been ongoing.
It turns out that some of this money may have disappeared without a trace and that someone involved in setting it up may be responsible...
Anyway the full story is here:

I doubt that money "have disappeared without a trace". It's quite an accusation considering the fact that it's been flat-out denied several times + there's a screenshot showing all the money.
Anna Zimmerman's piece is the best I've read about the subject: https://www.cyclismas.com/2013/05/no-g...good-deed/ |

Not sure whether this'll interest many, but anyway, today's Giro TTT showed that Sky have switched back from oval rings to round ones.
Some studies conducted on the subject show that an oval rings helps passing the dead-centre part of the pedalling movement (when the pedals moves forward or backward), but also requires a more important strength when pushing/pulling the pedals (on a vertical axis). The more oval the ring, the most important the strength during the push/pull phasis.
Overall, oval rings seem to benefit riders who hammer their pedals and make them pedal a bit "rounder", whereas it could be counter-productive on riders with a very round way of pedalling.
What was a bit surprising in the first place was that Wiggins used an oval ring, coming from the track he should have a very round pedalling style. Makes sense for Froome though, whose style is not very academical. |

I had heard about Wiggins switching from Oval Rings to Circular Rings earlier in the week. Apparently, according to the same report, Wiggins has switched back to mechanical gearing as well for the Giro after his electronic mishap at Trentino.
Coincidentally during one of the mountain stages (believe it was the first one) of the Tour of Turkey David Harmon and Magnus Backstedt were talking about the differences between the different setups available. Just going off what their experiences were, I found it interesting what sort of technicalities riding Ovals Rings brings to a climb, considering the size of the ring understandably varies depending on where in your pedal stroke you are with Oval Rings. |

In fact the global output is better when the power is the most constant during the pedal stroke. Of course it's very far from constant, even at the riders with the smoothest pedalling style. It matters more in climbs because riders pedal slower there (about 2 RPM less / % of slope), so the loss in output are more visible.
But as they also require more strength, not every one gets a benefit from them.
Regarding the mechanical gearing I've read the same about Wiggins. It's many riders in a row who've had problems with their Campagnolo electronic gearing recently : Valverde during LBL, Wiggins in Romandie, Coquard in Turkey. |

Well I cannot think of anything else to say or add to that topic after digesting all of that. Not due to an inability to understand it fortunately, I'm just lost for words you could say. So on to something else that may pique someone's interest.
I hear Cadel Evans appears to be riding a new model of bike at the Giro. Not that I could really discern the differences that well when my French is basically non-existent, and Google Translate really didn't do it much justice.

Quick translation then :
"Cadel Evans rides a new BMC prototype on the Giro 2013, that could be unveiled come the next TDF. No doubt it's certainly going to replace the ageing SLR01 that is still the first choice of BMC Racing Team riders.
But strangely, no UCI logo appears on the frame, though this is forbidden for UCI sanctioned events. No new frame either appears on the UCI list of accepted frames, and we are unaware of a potential code name.
Cables now run within the frame, which is of course conceived for Di2. Those cables go inside the frame in the middle of the top tube.
Little evolution has been brought to the design, and the rear part features the reinforcement below the top tube, which is a signature of any BMC frame. Note the saddle tightening screw has now been moved to the front.
There again, like every BMC frame, the seat stays have an important angle and join the seat tube almost in its middle part.
Inheritance from the BMC Impec, the seat tube grows to a huge diameter when joining the crank box. No worries there concerning rigidity, it should not bend.
The rear fork ends are very thin and not too deep.
Rests to know whether this frame will be built in the fully robotized factory which built the Impec, in Switzerland. In any case, BMC will have no right to fail, after the semi-failure the Impec has been."
Seeing those new bikes (not particularly that one) makes me wish I could afford getting a brand new one, one of these days.

Could this mean Evans gets a time penalty and forget about his GC?

I have no idea. I'm finding it odd in the first place that they didn't prevent him from using that bike in the race.
Most likely he'll get a fine that BMC (the frame manufacturer) will pay for him. |

Well, 2 years ago in the Tour, something was wrong with Barredos bike, and he got a time penalty, so I wouldnt rule that out yet.

Ever more curious about the differences between circular and ovalised rings I decided to do some more reading. Interesting that riders, such as Gregory Henderson and Julian Dean, subjectively found oval\osymetric rings missing something in situations where you want explosive power, such as in sprints. I couldn't be 100% sure but I don't think Cavendish, Goss, or Bouhanni were riding oval rings for Stage One of the Giro looking at the photos of their equipment.
I am curious as to why that may be. Maybe it links in to something Aquarius said earlier, I haven't been able to come to a solid conclusion myself yet.

I think oval rings are only used in TTs, though. |

I'd say it links to at least two things. The faster you pedal, the rounder things should be, which is why sprinters probably never use oval rings, and on the opposite that is why people who pedal more slowly with an orthodox style gain something when using them.
Second is that in moments you want to use explosive power you want an instant reaction, which is reduced with oval rings because it requires more strength to do the push/pull phases. |

A gearing problem has caused Cobo's crash yesterday aswell.
