I wanted to know what the proper frame size would be for a person who is 5'8" and 160lbs. Thanks

There isn't a correct size for any particular height. Many things such as the relationship of how long your legs compared to your core or trunk is influence the sizing. Other things such as your comfortable positioning on the bike influence size as well. I am 5'8" and ride 51s and 52s most comfortably. I was regularly and improperly sized on 53s for years.

You want to start with having some standover clearance, more the better, then move on from there.

Good luck.

I concur with the fellow who said that there is no way to tell for sure, that there are too many variables. Remember that one builders 52cm bike is not necessarily another builders 52cm bike. I disagree about the formulas and calculations recommendation, and even direct measurements on a "measuring bike" will not always be the most appropriate solution in many cases. I paid a fortune for a "Serotta measurement" which was done well, but yielded a bike that was too much of a challenge to ride.

The solution: if you are buying a bike that is currently produced and available in several sizes at your LBS, the best way is to first find the model that you want and try each of the sizes that seem to work best. Ride them for a while-more than just around the block-and adjust the seat, stem, bar position, seat position, and come to a final decision that way. If the dealer lackey gets annoyed about having to swap stems and move stuff around, calm the dealer by saying that yes you are buying the bike from them but you need to have them make the correct fit. Good Luck.

I've tried all the web calculations. They all told me different sizing and fits. None of which is what I consider to be my most comfortable bike. They'll get you into the ballpark though.

No substitute for a good fitting at a LBS
