OT, I find Strava is consistently lower than that recorded by my computer (Garmin with speed sensor) RWGPS is close or identical to bike computer but GC sometimes gives me rediculousy high figures.
Top speed. Chain rings ?????

Strava doesn't estimate the speed - it simply takes the data recorded from the GPS unit. In any case, I don't find that my GPS times are any different than from when I used to use a bike computer.

As an average in a ride Strava is fine, it measures distance and time and comes up with an average. As for finding an individual top speed, it is utterly hopeless and very inaccurate. For individual top speeds a bike computer is much more accurate. Some of the Strava estimates are frankly laughable. Either that or I am faster than many cars.

I was really talking about maximum speeds. I find that my maximum speed on Strava tends to be lower then what my bike computer records, although I'm using a mobile.

Guys - Strava doesn't do any of that. It only computes the numbers it is given by whichever GPS unit you use to record and upload the ride. You should be blaming Garmin, or Bryton, or maybe even the US Government's original 1973 Navstar programme - but it ain't Strava's fault.

Yes, sometimes, moving to a more aerodynamic position is more effective than pedalling harder.

Is that correct? Or is it a 53/12 combination? I'm new to all this gearing and trying to learn what I need to know for my bikes set up.
At present I seem to run out of gears at 50/12 when I hit 35mph going uphill.

It begs the question why you aren't wearing motorbike clothing as if it goes wrong at that speed, you are going to need some serious skin grafting.
As a beginner, you should focus on improving your ascent ability. I'm fairly pants, but have noticed an improvement in this with time.

Actually to some degree it is.

Well, I don't really see how Strava can be blamed, unless someone can explain...

As a beginner I AM focussing on my ascent abilities ( I never said I wasn't)
As I said before, I am generally happy with my climbing (still improving all the time)..... But I still want to improve this area of my cycling....... ' I Cant help the fact that I get a rush out of going fast down a hill'

Not quite, weight has quite a large bearing on the matter to.

Not in reality from my own experience, weight only has a large bearing on acceleration, so you benefit in situations where the pace changes such as when climbing.
On the flats, where aerodynamics can be up to 90% of your resistance, saving drag is the answer for increased performance.
My Tarmac is substantially lighter than my Venge, yet on the routes I ride regularly I am consistently unable to match the speeds and times I can do on the Venge when using the Tarmac.
Im with @Rob3rt on this one,

Without knowing their algorithms one couldn't give specifics, however, it is all in the data processing and you can do a lot with GPS data to correct for various artifacts.
