I'm noticing that if I'm riding in a decent cross wind (say 10-15mph), the Newton will often read super low power numbers (say 40w) when I'm working really hard just to move forward.
Is there anything I can to do to improve the readings? Note that I have the new mount where the unit sits in front of the handlebars on my road bike.
Thanks.

Re: Cross winds and the newton
I experienced the same thing yesterday. I had some significant winds on the ride and when I would turn out of the wind just slightly, my watt readings would drop to 0-50 watts even as I was climbing with the wind only about 30 degrees off the front. I wouldn't make a fuss if it was just for a second or so, but the interval was much longer. Any ideas? Is this a case where I need a remote wind sensor?

This is my same issue too. No big deal if it happens for a short time, but when you're riding long distances into cross winds, seeing 50 watts when you're killing yourself tells me something is wrong.

Re: Cross winds and the newton
There are several places in the attached file that show what I'm talking about. At about 1:03:59 to 1:04:55 there was no change in direction and cadence was pretty much the same and it was climbing a hill. I remember the wind was about 30 off the front on my left.
I'm wondering if the mount on my stem is causing the issue.

Re: Cross winds and the newton
Your ride file shows a sudden shift in wind from headwind to tailwind. Then it jumps up at around 1:05.
Were you riding in a group? Were you riding in the draft in this section? Wind speed drop is consistent with drafting.

Miles 34 to 36 or so. I'll try to do just a short ride in a cross wind.
But I consistently see very low wattage numbers in cross winds.

Re: Cross winds and the newton
The file I posted was riding solo. I also noticed the same thing from yesterday on my ride home from work. I can tell from my RPE that I was working very hard and the data shows a climb with a regular cadence and a power from 0-50 watts.
chris There was a brutal head or cross wind the whole way except the last quarter mile. When I look at the wind data, it doesn't tell that story.
This file is from a flat bar (cross bike) with no obstructions.
