Cervélo bike size

Good morning everyone.
I’m a Newby and looking for some advice please.
I was contemplating buying a second hand Cervélo S5 size 58cm which is in first class condition.
I’m 6’1” with a 33” inside leg. Would this bike be too big for me?
I currently have a Boardman Team Carbon which is 56cm which I’m looking to replace.
Any advice would be much appreciated.

    If you are spending a lot on a bike, I would definitely want to sit on it first, I have a 56 cm s3, 5’ 10” tall a 32 inside leg
    But I tried a 54 and 56 before I bought it.

    Ebay is flooded with secondhand cervelos, you have to ask yourself why

    My height and inside leg are both the same as yours. I've got a couple of Cervelos, both 58s, and they're a good fit. - I had a pro bike fit for them, to confirm the size before buying.
  • Thank you for your input guys. Much appreciated.
