@meutzi
Yesterday I put out 1450 Watts at the end of an endurance training ride for a few seconds, so believe me: this numbers are correct, he could do even more! What´s really impressive: 285 Watts @ 143 bpm, this is fucking amazing, with this average heartrate I hardly reach 200 Watts:(
@Keyobardbeatz, 6500kJ registered at the pedal, but human body efficiency is ~24% and J to calories conversion is 4.2, so that those factors nearly cancels out and you are left with ~6500 kcal consumed.
OK to dispel some myths.
Those numbers are totally plausible. 1450W max power is totally doable. I regularly do over 1500W on my SRM at around 90% max effort. My highest power output I did was 1778W at the Tour Down Under peak wattage competition measured on the industry standard Wattbike which samples at 50-100Hz. Way better than the 4Hz the SRM does. When I was racing 10 years ago I would easily do over 300W average on a 1 hour crit so 285W over 6 hours for a highly trained pro is totally believable. Froome does over 400W average in time trials and I would assume Fabian averages more than that over a 1 hour TT. Luke Durbridge etc are all around this mark for TT efforts.
As for motors.. The SRM measures power at the cranks. More specifically at the crank arm spider using 8 strain gauges. Not at the wheel as some posters have eluded to. A motor would have no effect on these numbers as it is not putting force on the crank arms. It would just assist rotation of the BB axle at best.
So in conclusion the number safe totally within reason. Drug assisted who knows, but definitely not mechanically assisted.
Jonathan Panoff A motor not affecting the numbers is wrong. It would lower the average power on the reading or make it easier for him than what it says. It depends on where the power is measured. Do you know why?
Who questioned the max power figure? 1450 is middle of the mall sprinting. I'd be more interested in his peak 30s60s,120s power figs
Yes. I can do 1200W staying on the saddle. Imagine out of the saddle.
@QuakePhil The SRM power meter doesn't really measure how much power the rider is putting out, but rather how much power is being produced at the rear wheel. There is a good bit of mechanical advantage involved via the crankarms and drivetrain, but essentially yes, he is putting out about 2hp max to the rear wheel.
Just because he produced 1450watts, doesn't mean he sustained it for any substantial period of time.It was probably just an output of a few seconds, which is very very possible for the likes of Fabian.Cavendish regularly produces 1500 in a sprint.
As for the avg of 285watts.That's probably still inside his zone 2 power, which is probably in excess of 300watts.Very plausible figures, I think.
Cav doesn't put out 1500w regularly. When asked, he once said he could do 1400-1450 max. No way 1500w regularly
Fabian is the King with 3-5k to go. At this point he can breakaway and outride the whole peleton. He is simply amazing.
The motor will increase the average and Max speeds. It will not affect the power measured at the crank...
285 watts ave for 6.5 hours is insane!!
What a great bike!
@glozick the computer isnt expensiv, its just the power meters in the pedal that costs more than 2000$
He continues to win
the most impressive thing is not the 1450 watt max but the average of 285 watt that's just incredible !!
Meutzi......I've been tested at Kent Uni in the Uk. I produced 1193 watts for 8 sec and ave 250 watts on my VO2 Max test. I'm only an amateur mtb rider. So, believe me when i say that data is very credible for a pro rider at the very top of his game.
thats pretty amazing. i have trouble holding 300W for 30 minutes
@meutzi Track sprinters put out around 2500W
I think it's 6h22' rather than 6' 22'' in the description.
fabian has the power of two horses one for each leg.
Be aware of something, not only the avg of 285w is impressive, but those world class riders can kick in 600W for 2/3 minute many time in the race, I want to say that i'm able to put down 270w for 4 hour and a half ( my all time best ride that left me in a top 10 local race ) but I would never be able to follow at 600 again and again and I would be drop at the first lil full fas hill
I have read a lot about his high cadence. His average cadence here was 73?
@apocrepa
I´ve got a Power2Max system, works fine and is just about 1200 € with a Rotor 3D crank
@QuakePhil Yeah he is putting out almost 2hp at his max power.
@mattsnow81 "when he broke away, it looks quite weird" - didn't look weird to me, or anyone else I race with. He's powerful enough to accelerate while remaining in the saddle - quite good for stealth attacks. No-one expected him to go that early, that's why it seemed so dramatic. You won't see that happen again because everyone will do anything they can to get on his wheel, even if there is 40 miles to go...
Where is the bit about his mini engine inside his bb?
@daFranch1se69 It seems those bike exist, and if you look at when he broke away, it looks quite weird... he seemed to suddenly take it cool while accelerating and dropping everybody! The videos of the acceleration are quite easy to find here, just type "Cancellara doped bike".
@glozick The crankset kit includes the basic monitor I think. Not much consolation considering the whole package is $3K. Amateurs use powertaps.
@meutzi Yes he does he's a monster =]
Jesus Christ, I just imagned what he could do in a velomobile with 285 Watts average. 70+ kp/h on flat... that would be great to watch.
is it 6450Watt instead of 1450watt?
Thats over 7000 calories burned. 285 watts for six hours is crazy.
@luyaosuperman are you outta your mind??
If one horsepower = ~750 watts, what the hell does this mean? 2 horsepower max?
@saucy05 6500 kj to calories is only 1500 calories burnt? surely he burnt more than 1.5k?
Pretty much all impressive...
Geez, has there ever been a better cyclist in terms of sheer power? A rider like Spartacus doesn't come around often.
This surprises you?
I max out at 200 bpm, but get no where near 1450 watts. :(
@Nenbran575
i work for Trek so I've gotta be pretty loyal...
please remember that this is a reading from a six hour race!!!six!!!!!
It's suprises me too, I wonder what makes it expensive ...
143 cadence?
Lets see how well he will do without Bjarne Riis by his side now that he has changed teams...
I have around 143 bpm 240 Watts and ANP 330 Watts/166 bpm, fabian has around 450 watts ANP i guess:DDD
@Descentia Power is energy/time - mechanical advantage is irrelevant.
no way he puts out 1450W... those number are wrong!
Yea right, try doing that after hours in the saddle at a brutally fast pace to begin with. Also, doing 2000 watts for 2 seconds doesn't count, not even for sprinting.
Hype. That's what. "Oh it weighs 30 grams less than our 500 dollar computer, which weighs 30 grams less than our 100 dollar computer."
7 ate 9
i can do 300w for 5 minutes
Trek are better than spesh.....
Everyone can do 1450 watts with an inbuilt engine...
new to the internet? no...
I've simply had enough of those stupid comments saying he was using a motor. Go actually outside for once, train for a while and then come and tell me that those numbers can only be achieved by cheating
