- Have you ever wondered what a #helmet, a #trisuit , aero socks or calf sleeves really bring on the table when it comes to saving serious watts?
Well, here you´ll get all the answers.
The second episode is all about comparing aero gadgets based on the greatest benefit at the lowest price.
Enjoy the second episode of our podcast special, that definitely makes you faster.

We know that a round tube is horrible aerodynamically but if a round tubed bike is your only option how about optimizing a wheel set and tires to the frame tubes? I know SwissSide don't subscribe to the rule of 105 .BUT how would choosing a front wheel which has a outer width matching the leading edge of the down tube and the rear wheel width matching the seat tube make a reduction in drag? If so, what a ballpark figure of the saving?
06:25 Aero sleeves save 6W, and 09:37 shaved legs save 12W, so 18W savings for calf sleeves on hairy legs?
20W on a frame, is that in comparison to a penny-farthing?? Or are you quoting at speeds of 80+Kph? ;)
See the Tour magazine tests, these figures are in-line with their testing protocol between good aero bikes and climbing bikes with little aero dynamic tube shaping - e.g. a Cervelo S5 vs an R5 with the same wheels.
@@morrisizing i would have been assuming they were comparing apples to apples not apples to oranges.... plus from the data table i am currently looking at from tour magazine (dont know the protocol whether rider on/off handlebars the same etc), a saving of about 20secs (foil vs addict) or even 1min 10 sec (s5 vs r5) over a ~4hour 18min timeline is no where near 20W... though as we know W values quoted on their own isn't very meaningful...
@fastasasloth according to the bike calculator 20watts extra from a baseline if 300watt over 40k @ 40kph would be about a minute saving over 40k at 40k an hour. The video suggested yo me moving from a non aero to aero bike, not between aero bikes given they know that the Van Rysel 'all-rounder aero+light' race bike they helped design gives away less than 10 watts to the Simplon full aero bike they helped design.
@@morrisizing i can only repeat the data i see from tour magazine (which you initially highlighted not me) which gives about 20-80 seconds saving over 180.2k (between a manufacturers aero frame or "light" frame), not 40k And what W saving does that indicate at say 25mph? It's a rhetorical question since it's much less than 20W... plus the video said "good bike frame to a bad bike frame", not bike! I'm debating what was actually said, a 20W difference between frames... and that to get such a saving one has to have a large discrepancy in frame type (hence the exaggerated penny-farthing quib..) or be travelling hell of a fast (hence the 80+kph quib..)
is that 12w with normal mid-calf socks or no socks/short socks? you'd assume mid-calf length socks are negating any aero drag from the lower leg. so is shaving basically just my calves worth 12w? and how are calf sleeves only 6w? you could argue those are more aero (applying some rough principals of kit materials aero properties) than bare legs? legit questions as i can admit this is mostly bro logic lol
Again, not one word about rotational wheel balance, which is just as important as Aerodynamics...
It is a discussion about aerodynamics, not other aspects of cycling performance or general physics 🤡
@@_msc-ds9sj A mind is like a parachute, it has to open for it to work. If you read or know Newton's first law it does not exclude aerodynamics from balance because it is the same subject.. By the way, cute clown, is that a portrait of you?
