Thanks all for the input thus far. One more clarification:
It seems as if the Ergomo has 2 potential problems:
1. Finicky to install
2. Difficult to calibrate or maintain calibration.
I don't get it - the only "problem" when installing Ergomo is to find out if and how many spacers you need to apply for a correct installation - in short - achieving 9 o'clock positing of the cables in relation to the ground ... That takes approx. 4 minutes... For ISIS that might take 5 minutes as there are additional spacers that need to be added…
How can be difficult? Of course - if you are a person that goes to the LBS to change cranks or BB, than I can understand that installing Ergomo might be a challenge - but so will be installing the SRM system (to make myself clear – there is nothing wrong with that). PT gets laced to the rim and if you don’t do your own wheels you simply buy a complete rear wheel - so here installation is cut to installing the computer and receiver (the shark-like thingy).
As for calibration - well, checking the offset (as advised by the manual) is relatively painless – it takes sth around 30 seconds and it only requires you to spin the crank (left) at 50 – 70 rpm for about 20 seconds…
And you can check if Ergomo is off: (taken from the manual):
Verify the OFFSET with the following steps:
1.) Select the biggest gear ratio, i.e. put the chain on the
smallest sprocket on the rear wheel and the largest
chainwheel on the front wheel. Ensure that the rear wheel can turn freely.
Turn the
right crank at about 60 pedal turns/min. Turn the pedals smoothly and without jolting. Please watch the ergomo pro computer display while doing this. Display power
right should be between
0 and 5 watts.
2.) Select the biggest gear ratio, i.e. put the chain on the
smallest sprocket on the rear wheel and the largest
chainwheel on the front wheel. Ensure that the rear wheel can turn freely.
Turn the
left crank at about 60 pedal turns/min. Turn the pedals smoothly and without jolting. Please watch the ergomo pro computer display while doing this. Display power
left should be between
5 and 15 watts.
And that is it.
