a sloping top tube, frame type,means the seat tube is shorter,
in relation to the top tube as a horizontal distance..
I encourage you to go to a LBS where you can stand over the frame , and see what clearance is like
I go by top tube length , , but even that there is a range ,
stem length and riding posture influence that part
seatposts are made long , with sloping top tube , more is extended..
I have bikes, several. with a 54 +10 stem .. 56 with a 5 those : trekking bars
57, cross-bike with a 9, road bike with an 8.
and a 60 with upright bars and a big rack in front., short seat post extension..
