Your quoted aero savings are a bit off. And as pointed out... “compared to what?” That last part is key. Plus, aero gains are not 1+1+1=3.Jack65 wrote: ↑Wed Jun 05, 2019 11:21 amAero Overshoes will be used. Velotoze or similair.
As for chinese carbon aero frames, I see many PlanetX aero track frames on the velodrome. And they seem to be pretty good.
For us, amateurs, I love my Spec Roubaix. But certainly it's not a very efficient bike. One of the easiest ways for us for saving watts is wheel sucking As well as lowering position and learning how to ride in aero hoods position. Steve from "In the know cycling" has very good review of latest aeroroad helmets and they do seem to save some watts.
As for weight vs erodynamics, I first appeared on local group rides many years ago with 15kg trekking bike. After mounting cheapest aerobar I was able to sustain 36-38 km/h speed with them. It is also worth noting tha Ondrei Sosenka, who has beaten an hour world record, was using 3kg wheel at the back (http://www.wolfgang-menn.de/sosenka.htm).

Skinsuits: Again, incredibly subjective. A poorly fitting skinsuit can cost watts, but a well fitted one can get big chunks of time, somewhere in the region of 10-15 watts versus a normal jersey or maybe more. Rules of thumb are avoid wrinkles and exposed skin.

I think it's important to note that exposed skin is preferable to wrinkles, and why a few non-custom skinsuits use short sleeves. But yes, buy the smallest skinsuit you can possibly fit in without tearing it apart at the seams.
Argh, didn't realize chatting and riding side-by-side was harder than just being out on the front alone... wow.

Riding and chatting is definitely harder than just riding. Tends to be less aero too, because we don't usually chat while in the drops. So it's just bad practice, all in all. Shut up and ride.Johnny Rad wrote: ↑Thu Jun 06, 2019 3:47 pm

With the upcoming release of the Madone SL this will now be possible.Richards1987 wrote:Does anyone know if you can put a different bar and stem on the 2019 Trek Madone SLR Rim Brake? I am looking at buying the Trek Madone and am trying to bring its weight down as close to 6.8kg as possible and believe the madone specific stem and handlebar is quite heavy (>500 grams). Was thinging the 3T Aeronova team stealth handlebars and 3T ARX LTD stealth stem?
I read this a lot about the full mannequin being 200 watts slower but there are plenty of videos on youtube showing real-world testing at 45 km/h being, in some cases, much lower than that. The tests that cycling weekly did with Dan Bigham are a good reference. In their first tests, they compared a vias, madone 9, aeroad and cervelo S5. The differences were about 80 watts greater than tour test results for the similar bikes using the rider in the aero hoods position.AJS914 wrote: ↑Fri Dec 21, 2018 3:55 amIf you add the legs to the manequin and it adds 200 watts you are looking at 403 vs 413 watts to hold the 45km/hr or a 2.5% difference.robeambro wrote: ↑Thu Dec 20, 2018 9:29 pmThis test seems to suggest that not all aero bikes are created equal. Some will give an advantage, some may not.
Weirdly enough, I may buy a Ridley Noah Fast, and it will be "much slower" than other aero bikes, virtually as aerodynamic as a Tarmac SL6.
In other words, you buy an aero bike, it looks faster (cause the Noah does "look" faster than the Tarmac), but at the end of the day for some of these bikes the wattage saving is just not there.
