What size for bike?
I am 1.81 m, inseam of 83 cm, my reach i.e. from shoulder to knuckle is 69 cm what size should I be using?
Hi there, right, I've been doing some research, and if you're 1.81m, then your about 5.9 in a half....
So ideally, you should be on a 57cm frame.
I'm about 5, 8'' and I would be best suited on a 55 cm frame.
I'm also quite short in the leg, so that is spot on for me. If I was, to get on the 57cm, it would fit, but I would be way too stretched out on the handlebars, also, I would literally be right on the tip of the toes.
You are a little bit taller than me with an inside leg of 83cm, so I would highly reccomend that you go for the 57cm frame.
Sure hope this helps, if you have any other queries, please feel free to ask.
