Is there a preferred frame size calculator? I am buying a new road bike. I have looked online for calculators but I am getting different answers on which frame size I should get. I've got 53 cm on a calculator that only considers inseam height and 56 cm on another one that also considers riders height so I don't know which one is correct because I don't want to end up with a bike that is either too big or too small for me.
IMO Frame size is more than just measurements. A proper bike fitting pairs your riding style &amp; level with the frames own handling characteristics. (defined more by tubing and angles than measurement alone)

BUT... not everyone's out to get a custom bike frame made or go research their frames butted tubing or headtube angles... But I always suggest visiting a place where they know how to "fit bikes" (for racing, touring, etc) and getting advice from a bike fitter.

Don't forget to buy a water bottle and power bar while you're there, chances are they don't charge you for the advice. #smallbusiness
