Definatly a 17. Im just about 5'4" and i dont fit in a 16.5. I have a long leg, so i need a 17 with a long flap. just know what you need and then look
17 especially because you are growing
Omg 17 would be huge!! Def a 16.5-
5'6" and slim and I ride in a 16" saddle but am looking for a 17" bc my legs are so long. I recommend getting 17".
id go with the 17, you can always grow into it .
I would do a 17 since you can grow in it
I am 5'6" and I ride in a 16.5, that said I think would be completely fine in a 17. Since you're still growing a 17 might be perfect so you could keep it for a long time!
