Can’t decide between the 16″ and 18″. Im 5’9.5 and wear 30″ inside leg trousers (although I tried measuring and got 32″). The guides suggest I am the absolute smallest an 18″ would fit but at the very top of the 16″.
Im thinking 16″ but only because the 18″ is out of stock. Am I going to make a big mistake with the smaller frame?
I’m exactly the same size as you and have a 18″ Summer Season which works great with a 70mm stem. Having said that i’ve longer arms than most and don’t like long stems for the sort of riding 456’s are best at.
