What about Gradient Lag?

I already changed 5 units because of issues so don’t lecture us about how good the product is. 1040’is not a solid product and the gradient is a joke. Garmin should have fixed all the issues after years and  many customers are quite unhappy . I do not have a single friend using edge who is happy.  

This is not an isolated problem, but affects many users. In my only cycling group, we are 2 owners of garmin edge 1040 solar and after working very well for months, the slope and altitude are now currently wrong. Take a look at the image...Weather was sunny.

I'm not lecturing anyone, just sharing my own experience, so calm down, lets keep this civil. Out of interest I just pulled up data from a regular ride i've been doing for more than 15 years from veloviewer the same ride with elevation data from the four different Edge devices I've used over the years the 800, 1000, 1030 and 1040. The elevation profiles are essentially identical, up and over Box Hill and the max and min altitude is within a variation no more than a metre? That's good enough for me. The data from those rides came from the units I don't use the strava elevation correction, even though it probably does a little smoothing.

Before all you nerds start criticizing this as not scientific, like I said it's good enough for me. If the 1040 was that bad I'm sure I would see a significant difference compared to the other units (I don't).

There might be something in a lag of real-time display of elevation out on the road but that's not important to me, I tend to enjoy my surroundings when out riding rather than fixate on my head unit. As long as the data recorded is accurate that's  important for me.

Also I'm more interested using it's navigation function and  in Power, Heart Rate and speed etc. so I can measure my fitness over time I think Garmin is way ahead in that regard, I have Garmin watches which are great at monitoring 24/7 fitness data like HRV etc. The best thing for me is the Edge unit and Watch work together through Garmin Connect and provide free data analysis of how your body is affected by your training. The equivalent would be whoop band which is a very expensive subscription service and the device has no other functionality.

I'm sorry, but knowing that the garmin edge 1040 is supposed to be the top of the range, I find it hard to accept that over time this GPS displays incorrect slope, altitude or elevation values. Given the price, it's logical not to expect the same performance from a garmin edge 1040 solar at 600€ as from an edge 130 at 130€.  So comments like: "I don't use the navigation, slope and altitude functions anyway, so it doesn't matter". It's like saying it doesn't matter if your smartphone can do everything except make phone calls. Knowing that Garmin is aware of the problem, we're entitled to expect them to solve it, or at the very least to accept that there is a problem and that they're prepared to repair or replace the faulty device. For those of you like me who have an Edge 1040 with a large screen, we bought this model to take advantage of the screen's features. So to have a slope indication at -4% when you're on the Angliru climb (at 22%), and to find yourself at the end of the outing with a positive vertical drop of 600m when it's 1200, I wouldn't call that a time difference.

I think your unit is broken, I'd call it in as a fault. Mine is fine never seen what you describe. I'll leave you guys to to it, hope you get a resolution to your issues.

Good grief. I have a trip planned for a couple of weeks and was going to jump on this thread to see if the lag was resolved because I've been on the trainer for a while--clearly not. Time for the lawyers! :-)

That is really not a valid comparison although I do understand your point.  However, I do not know of any product that promises every single feature offered will work perfectly every time for every person in every condition.  If you say to qualify as a bike computer a unit must do at bare minimum a certain set of features like speed, power, cadence, distance, hr, etc then i'm sure the product qualifies as not being knowingly deceptive.  So for anyone to hang their hat on any one sub feature, while your right, is not necessarily a point of re-design for the company.  I'm sure they would want it to work perfectly for everyone every time, but just like any other complicated piece of engineering, it does not.  There is no fine print guarantee that states it will.  It sucks, it can certainly be a defection point for you and others in the same boat.  However, it is what it is.  I would pursue that perhaps you have a faulty unit, maybe another would be better. 

Do you work for Garmin?
