I have an option to buy a road bike that has the height of the frame 54 cm : https://www.willhaben.at/iad/kaufen-und-verkaufen/sport-sportgeraete/top-rennrad-ktm-strada-nur-9-3-kg-alles-shimano-ultegra-132209154/ . I am 182 cm tall. When I went to a shop and asked the "expert" about the bike, he suggested me to buy the bike with a frame of 56 cm.

Is there a big difference between the two sizes? Should I buy the bike, or it doesn't fit to my height?

    Measure your inseam and use one of the many sizing charts / calculators on the Internet. – paparazzo Sep 3 '15 at 16:11

    You need to try it and see how it works, but I'm going to guess it's probably not going to be a good fit. For what its worth, I'm 180 cm and my preferred road frames tend to mostly be 58's. It depends on arm, torso and leg lengths and personal preference. – Batman Sep 3 '15 at 23:34

    I'm 182cm and all the bikes I own are 56, except for one cyclocross bike which is 54. But then my older 1990 steel bike has a much longer top tube than my more modern 2012 bike. In your place I'd go for a 56cm. This said a magazine claimed that Peter Sagan rides a bike that is actually smaller than his fitting size because the frame is lighter and stiffer! – Carel Sep 5 '15 at 8:08

I am 175cm tall. I rode a road bike recently with a 56cm frame. I it had been any bigger I wouldn't have been able to ride it safely. 54 or 52cm would have been a better fit.

I suspect that a 54cm frame would be a bit small for you, but not painfully so. Get a 56 if you can.

I am 183 cm tall and ride size 55. I have relatively short legs, so I had a custom frame with longer than usual top tube made. For a person with more usual proportions a normal 56 would probably be fine. As already said, it depends on the exact dimensions and angles of that particular model.
