Tour de Suisse 2025 - Men's (June 15- June 22)

They consider 6.78 w/kg if pogacar is 66 kg.
If he was 64/65 kg is probably around 6.8 w/kg.

Since they do in standard weight 70 kg to compare the perfomances of riders with different weight, they consider Pogacar did 6.75 w/kg (473 W/70 kg) and Vingegaard 6.61 w/kg (463 W/70 kg).

I swear; I did not come up with those calculations!

 

[Red Rick]

If they are pretending every rider weighs 70 kg, why don't they just report Watts and ignore the per kg bit?

May as well say that if I standardise my weekend ride to 1 hour, I rode at 78 km/h.

I'll ignore the watts and only report the kilos.

Quoting standardized w/kg based upon a rider weight of 70kg should be avoided at all costs - it just confuses.

Just use their actual weight - that is the entire point of comparing rider power to weight. Of course a 70kg rider can be expected to generate more absolute watts than a 50kg rider.

Otherwise as Armchair cyclist says just quote watts.

 

[QueenStagiaire]

Okay, so we‘ll standardise for 430 watts now and calculate the kilos, exciting. I think we can agree on this, right?

The best thing to do is saying "standard watts, and then we can forget about w/kg.

No. The most basic physics says w/kg is what determines climbing ability. Standard watts just muddies the water.

But you can't compare w/kg without being in standard weight.

A rider who is 60 kg will do different w/kg than a rider who is 67 kg, if they climb in the same time.

A rider who is 60 kg will do different w/kg than a rider who is 67 kg, if they climb in the same time.

A standardization can be used to describe the efficiency of pedaling watts for each rider.
The actual numbers can be used in direct comparison between riders under the same conditions up the same climbs.

You can also standardize a power/weight figure and then calculate VAM/kg and not care about which rider reaches the summit first. I know that some commentators will go berserk in standardized numbers without lifting their noses from the papers - where they then suddenly have to concentrate on weight * aerodynamic numbers instead, same riders at another ball game of speed.

No. The most basic physics says w/kg is what determines climbing ability. Standard watts just muddies the water.

The point is that, due to bike mass being different fraction of body mass, various riders need different w/kg to climb at the same speed (VAM). To achieve some performance (i.e. 1800 m/h) a 70-kg guy would need let's say 6.4 w/kg while a 60-kg guy would need 6.5 w/kg to match the first guy (relatively more of his power is needed to lift the bike). Those differences aren't big but they exist. Standarized w/kg is just to compare w/kg without this bias (i.e. standarized value for a 65-kg guy would be around 6.45 w/kg).

Curious about grams of difference between elite level climbing bikes..is that weight, either standard or difference between top bikes used by top riders..? It's my understanding that most bikes for climbing border on UCI lower weight limit
