" Tomorrow, if I put the same watts on the bike that Lance Armstrong had in 2000, I'll climb the Alpe d'Huez five minutes slower than I did on my bike today. "
French cyclist Nans Peter, currently with Decathlon AG2R La Mondiale and a stage winner in the 2020 Tour de France, was asked about doping in cycling and brought up a curious example with Lance Armstr...

Perhaps your post was meant to be ironic, but I would like to counter this.
I have some serious doubts about this claim.
Let’s break it down: the Alpe d’Huez climb is 13.8 km at an average gradient of 8.1%. For a pro, that’s around a 40-minute effort. Claiming a 5-minute difference means a time loss of over 12%, which would translate into 50–60 watts of additional drag or inefficiency. That’s a massive number – and frankly, it doesn’t add up.
First, let’s talk bike weight. Armstrong’s Trek Madone from the early 2000s was already hovering around the UCI weight limit of 6.8 kg, which is still in effect today. So from a pure weight perspective – especially on a steep climb like the Alpe – there’s no real disadvantage. Weight remains the dominant factor when climbing, not aerodynamics or stiffness.
Secondly, modern bikes are undeniably better: more aero, stiffer, smoother shifting, better rolling resistance. But on a climb where you're going 15–20 km/h, aero drag is a minor factor. Even drivetrain and frame stiffness improvements don't yield massive gains at those speeds. In practice, you might save 30 to 60 seconds, not five full minutes.
To add some real-world context: I’ve been riding the same local 63 km loop with about 500 meters of elevation gain for over 20 years with my cycling group. That route includes flats and rollers – where aerodynamics and stiffness actually do matter more than on the Alpe. Our average speeds have remained between 36.5 and 39.5 km/h, depending on wind and weather.
Yes, we’re all getting older – but the group constantly refreshes with younger and faster riders. And let’s be honest: we also consume far fewer beers and gin tonics than we used to on the weekends. Training is smarter, recovery is better. Yet, no revolutionary jump in speed, despite riding the latest high-end gear.
Finally, several independent tests and engineering reviews (e.g. Tour Magazin, CyclingTips, Hambini) have measured the performance difference between early-2000s race bikes and today's top-end models. The total gain on flat terrain is around 10–15 watts, depending on tires, drivetrain, and aero design. On long climbs, that benefit drops to 5 watts or less. That’s nowhere near enough to justify a 5-minute deficit unless the rider's legs also went back to 2001.
So yes, modern bikes are technological marvels. But the idea that riding Armstrong’s old Trek would cost you five minutes on Alpe d’Huez is, frankly, marketing myth or smoke screen...
