Hi im new to biking and I recently got a Scott speedster 20, I wasn't aware it was a Traditional road bike when i bought it.
I think an Endurance type of bike would fit me better as I want comfort for riding long rides and don't care that much about speed.

Right now my arms are uncomfortable and not that much bent, pretty much straight arms, old style of fit- long, and low.
It's almost like sitting like this https://i.imgur.com/2mCoKcR.jpg

Is there a way to change the stem or something so it's more comfortable and is like a more endurance bike? may spacers help abit?

move the saddle forward

You can try a shorter stem that is angled up more.

Thanks, will try

Check if the seatpost has 'setback'.
if it is a Syncros seatpost they use the term 'offset'

The Speedster is (or was) Scott's idea of an endurance geometry. The newer Solace range is more so, though, with even more stack and less reach, but . . . Endurance is what you make of it. I'm not offering advice unless I can see how you're sitting on the thing. Ask your local dealer about short 25-degree handlebar stems.

Thanks, it feels alot better with the 25 degree stem, looks kind of ugly though but as long as im comfortable i'm happy!

First off, do not use your saddle fore-aft to control for reach to your bars. This should be set to optimize for where you want your center of gravity in relation to the bottom bracket, neutral (further aft) or aggressive (further forward). Once you have that set then change the stem length and angle to adjust for arm reach. Do adjust this you can 1) flip your stem, 2) use a shorter stem or 3) use a stem with a greater angle like your 25 degree stem. Also you can move the brifters higher up the handlebars to bring them closer to your hands, but make sure you can still control them from the drops.

I remember that photo. She has long arms and legs. At first glance, she looks implausibly stretched out on a frame and stem that are too long for her. But looking more closely, it appears she is momentarily slumped in a state of exhaustion on a long climb, forgetting to rotate the pelvis forward, and hanging a bit off the back of the saddle. I've been there, too.

On the other hand, it's possible the bike might be a bit too large for her, and she might benefit from a little less reach (because of the short torso) and a bit more drop (because of the long arms). How this relates to you, I don't know, because you're not the rider in the photo.
