Which frame size to choose?

Hallo,

I have some difficulty deciding what frame size to choose. The manufacturer table seems to suggest size L but it is very close, size M might be more fitting. Could you be so kind and help me choose the correct size?

My height is 179cm
My step length is 81/82 cm
arm length is 61cm

The bike I want to buy is called Wilier 503 Race 29

Kind regards, Martin

 

Can you ride both sizes?

If you're not racing as professional I would think comfort would be the way to go which means you want a Large.

See this for another size viewpoint, just scroll down to road bike size chart:

This decision is yours obviously, but realize you'll have to live with that decision.
