This is similar to another thread from last year, but different enough to be worth asking.
I ride what is basically the same route from home to work & back, but sometimes it's for exercise/training & sometimes it's the way to get from A to B. On the latter I often have a significant sized rucksack (10-15 litres & up to about 5kg in weight)
Distance is about 34km & there's about 500m of climbing in the downhill version of the route.
I'm curious about the effect of a 6-7% increase in bike weight might be (plus the effect on the CdA of having a parachute for the faster sections), but that currently stops short of doing a full profile calibration with the rucksack load on board!
Can I just duplicate the profile & add a bunch of Kg to the rider weight? Or should I add it to the bike weight?
Should I tweak the CdA at the same time? (is it different if I add weight to a different component of the total weight?)
I've not got an aeropod/way to easily measure CdA so if someone wants to throw a best guesss in here that would be good

Re: Best way to handle commuting with a rucksack
1) Yes, you can duplicate the profile and add weight in the Edit Profiles command.
2) It's likely that your rucksack adds drag. My "GUESS" is about 10%. You can update this in Edit Profiles, too.
3) You're correct that AeroPod would be able to quantify the change
4) If you have multiple profiles for the same bike, you'll need to switch manually between them.
