Hey Guys first post!

Looking to get a vigorelli steel frame for long distance rides. 60-100 miles, got fitted for a bike and found out im a size 55.

So my question is: should I order a 54 or a 56? I currently have a 54 parallax, and will be upgrading to a 56 b/c its a little too small. I know the vigorelli's are much more relaxed!

Thanks in advance!
