WATTAGE DIFFERENCE

[JOHN WALKER]

I Pro: Fitness test: 20mins: Av Watts : 116 on CycleOps Fluid 2 Trainer.
Next day: Fitness test: 20 mins Av Watts: 320 on almost flat track.
How can this be?

One could be low and the other high. The answer could be in between.

Seriously, the trainer settings can be altered - if you open your trainer file again and the change the trainer setup - you may find another Cyclops set of parameters that are better in line with the road results. (I think there are as many as four different Fluid entries.)

The next question becomes one dealing with the road calibration and how good that is. If you have good values from the cal ride and coast downs, then that is probably a believable result for the road test.

The choice then becomes one of changing which trainer values you are going to use. The wheels and so on on a trainer are not going to play that much on a power set up - it is the resistance in the mechanics that factors most.

Try some other settings and see how things match.

I vote for the trainer session being the issue first and foremost. To me, 116AP indicates a unit that was not in trainer mode so it saw massive negative wind. There could be many other factors including a profile that's not right, but my money goes on not being in trainer mode.

And that's why I have very little money
