Re: Difference between aero and road helmet profiles

Thanks for all your help Fernando - you've put my mind at rest! I'm glad that's all working properly at that, as you said, my setup is dialed in now! I am using a TT setup, with the steer tube mount - I'll post a picture soon and you can see what you make of it. It's all tightened down a lot so I do...

Re: Difference between aero and road helmet profiles

Thanks for the info - but why does the unit not display 0.0% when it is on flat ground if this is the case?

Re: Difference between aero and road helmet profiles

OK so I did as you said - I made a new profile so I could keep my old one just in case, I did a tilt cal first, rode to the site, did a wind cal, did the out and back cal ride, and then most of the out and back route again ( had to leave because of time but there is enough there). I have to say I'm ...

Re: Difference between aero and road helmet profiles

Also, will this completely make my readings unreliable, or will they just be scaled slightly wrong - i.e. 210 watts on the Newton might actually be 230 in real life, but 220 on the Newton is 240 in real life, or is the relationship not linear? The reason I ask is that I did a FTP test yesterday just...

Re: Difference between aero and road helmet profiles

Thanks for this - I will try to do that some point this week. How do I do a tilt cal now that it's not in the setup menu anymore?

Re: Difference between aero and road helmet profiles

Sorry to add more to this but I just looked at a seperate ride I did yesterday with my road helmet profile and it's showing effort speed as pretty much always being higher than my actual speed i.e. headwind the whole way. I have the RWS on my left handlebar - right up by the brake - do you think thi...

Re: Difference between aero and road helmet profiles

Also I should mention this is using a TT set up, steerer tube and RWS, is this still the sort of number you'd expect to see?

Re: Difference between aero and road helmet profiles

I don't have my road bike cal ride anymore (at least it doesn't seem to download it) but here is the one from the aero helmet. Thanks for looking at this.

Re: Difference between aero and road helmet profiles

Thanks for this - any thoughts on the windscale numbers?

Re: Difference between aero and road helmet profiles

Also, when I download the cal ride, it comes up with 3 cal rides - one 2.6 mile (while I was riding to the course), one 4.0 mile (which is the actual cal ride that I started from the setup menu) and another, 2.8 mile ride where I took a slightly different route riding home again. After the 4.0 mile ...

Difference between aero and road helmet profiles

So I recently recalibrated everything as I was worried my readings were a little low (on different days of different temperatures, which can't be helped, but did do a wind cal before both and it was on exactly the same course). My road bike helmet profile seems great now - I'm getting the readings I...

Do I need to set the elevation for accurate readings?

I always thought that you could set the elevation after a ride in Isaac and this would just adjust all your altitude readings. But the more I read into it, the more I wonder, do I need to set the elevation each ride to ensure accurate power readings - ESPECIALLY on the cal ride? Also how much is one...
