Ribble winter trainer/audax size advice?

[manickode]

I'm 189 cm with a 90 cm inseam and according to Ribble size calculator I should be a 62cm. (In traditional frames I'm a 58 cm)
From what I've heard they have an aggressive geometry but when looking at the size chart a 62 cm frame with 58 cm top tube and 19.5 cm head tube seems quite reasonable?

One side note to this however, it says it has a horizontal top tube however the frame appears to have reverse slope to it on the actual picture, What impact does this have on length and the given measurement of the top tube?

Any advice or opinions appreciated, thanks.

If you are a 58cm traditional frame size, what does that actually mean?
It has a horizontal (level) top tube. the photo is misleading and horizontal top tube is what you expect from a "traditional frame"
Confused?

Is the 'traditional' 58cm centre to top or centre to centre? I have a Ribble winter bike and the centre of the top tube is about 45mm below the top end of the seat tube. The top tube is 55cm, and the seat tube 54cm centre to top. If you subtract 4 - 4.5 from 62 you will have your 58 - if centre to centre of course. The practice of measuring centre to top is not very helpful, as the length of seat tube above the top tube - real or virtual - can vary so much. (NB my Ribble is a few years old and the frame is not exactly the same as the current one).

Can you get yourself to Dolan Cycles or Surosa Cycles?

Their winter trainers appear to be almost identical frames.
