Been riding with the iBike Aero for a few days and am enjoying the power experience immensely, however one issue that is conspiring against me is a certain type of road surface... that being the very poor condition surface where much of the tarmac has worn away and the stone chips are exposed. When riding over such surfaces the bike starts rattling away and power display often drops to zero even though the same, or indeed, higher effort is being made to get over the poor surface. This was a real problem during an FTP test a couple of days back because after 15 minutes of "busting a gut" I encountered such a surface and power simply vanished.
Does iBike compensate for these conditions during Route Analysis?
Also, while riding, if moving from an older asphalt surface onto a newly tarmacked one, there is an immediate jump in power, even though power from my legs is the same. Again, does Route Analysis recognise these sorts of transitions or does a change in speed (due in this case to lower road friction) always indicate user power input? Am I to assume from what I've seen that power is always going to be a little off depending on the road surface?
In the iBike software I have general settings set to automatically analyse downloaded rides. But after downloading, if I do a manual analyse route the results always change. Are these two separate analysis, or should automatically analysed routes give same results?
Regarding wind offset. Was out on a five hour ride today and checked wind offset regularly during the ride and each time it had drifted. I reset and an hour or so later when checking, it had drifted again. Temperature was very variable today with a 14 degree F shift during the ride. Do I need to be concerned about this? Do I *actually* need to recal during a ride or will the iBike post analysis take care of this drift?
Regarding the initial wind offset, is it ok to do indoors? I leave my unit outside to acclimatise to temperature and then stick it on the bike indoors to do wind cal before nipping straight out again on the bike. I figure there's no wind indoors so it's the best possible wind cal???
Could the software be updated to allow user selection of how temperatures are displayed? I display distances in metric, but want to show temperature in Celsius as I don't do Fahrenheit...
I guess that's enough for now
