Hey Y'all
I have been searching for new to me tri bike after my ten year "retirement". I have been looking online and have been communicating with someone selling a 2015 Kestrel 4000. He says it's a size 52.5 but that he is 6'1". It's about an hour for me to go ride the thing and wanted to see at 5'8 if this is even going to be a close fit.

What other questions can I ask to make sure I'm not wasting the drive?
