calbration
hello as you can see in the descents the watts are fired whith hardly any effort even without pedaling.can you tell me if it is correctly calibrate..thanks

Por favor puede ayudarme ?? gracias
Re: calbration
The small section with high watts was at high speed and large headwinds. If you went into a tuck in the descent, to pick up more speed, that would be the reason for the high watts.
Everything else looks normal.

Re: calbration
Pero en un descenso vas a gran velocidad...de acuerdo....pero solo por mover pedales sin llegar a dar fuerza para a la bici puedes dar 700w y hasta 1000w????
Sigo teniendo el mismo problema en los descensos... después de una nueva calibración...sigue dándome watios sin apenas pedalear e incluso sin pedalear mantiene watios muy altos...estoy muy decepcionado...no encuentro solución....

Re: calbration
This is not a calibration issue.
1) when traveling downhill, any differences in ride position are critical. On downhills if you go into a tuck, to go faster, PP does not "know" you have become more aero. Instead, it attributes the extra speed to your pedaling with more watts.
2) When cadence = 0, watts = 0. So, whenever you are not pedaling on downhills, you won't encounter the high watts issue, no matter how "aero" you make your ride position.
3) Your ride file shows that, when you are not pedaling, watts are zero.
4) You can "fool" PP by riding in a tuck and then soft pedaling, but there is no cycling benefit in that.

Re: calbration
Gracias por la respuesta
Pero decir que antes de la nueva calibración esa situación no me ocurría.... también decir señor jhon que el mismo pp debería saber si en un descenso con ese movimiento tan lento de pedales es suficiente para generar esa potencia...ya que es irreal los números...y por último,cuando vas en llano y una velocidad ya alta puedes mantener los 400w e incluso más...durante tiempo,dudo que pueda ser así ya que en pendiente apenas mantengo 250-300w.
Espero encontrar una solución
Gracias por todo.un saludo!

Re: calbration
Please post one of your earlier ride files, where you say there was not this problem.

Re: calbration
te doy un recorrido antiguo y ves que en el mismo descenso da valores mas coherentes que los de ahora
tambien te doy otro recorrido de mhttp://velocompforum.com/download/file.php?mode=view&id=5089tb para que veas que con cadencia 0 da valores de wahttp://velocompforum.com/download/file.php?mode=view&id=5088tios...

Re: calbration
It is EXACTLY as I thought, and this is instructive for everyone.
Your 1/11/17 ride shows "normal" 241 watts in the descent between mile 5 and 6
Your 8/20/18 ride shows "high" 580 watts on the same descent, between mile 5 and 6
You say that you did not pedal harder on your 8/20 ride. Why, then, is there such a large power measurement difference? The detailed stats provide the answer:
On your normal-watts, 1/11 ride, you descended at a speed of 24.5 mph, and your heart rate (directly related to your power) was 146
On your high-watts, 8/20 ride, you descended the same hill at a FASTER speed of 30.6 mph (6.1 mph faster) , yet your heart rate was LESS, 134, meaning that your body was not working as hard.
How is it possible that, on your 8/20 ride, you went down the same hill FASTER, but with LESS EFFORT from your body?
ON YOUR 8/20 RIDE YOU DESCENDED THE SAME HILL IN A TUCK; YOU WERE MORE AERO, AND SO YOU WENT DOWN THE HILL FASTER!!
As I said in a previous posting, PowerPod does not "know" when you become more aero; when you become more aero relative to your normal ride position, PowerPod attributes the extra speed to you pedaling harder (more watts).
It's also useful to note that "aero watts" increase as the cube of bike speed, so as you descend faster, aero watts differences measured by PowerPod will become GREATER.
There is nothing abnormal about your PowerPod readings.
One other thing: our new AeroPod will measure CdA differences caused by changed ride positions, as well as quantify the time advantage benefit of the improved ride position.
