Ergo handlebars are similar to the traditional bars in shape only. Ergo bars have a 'flat' section in the drops which makes it so your wrists are in a more natural position. Thus helping to eliminate strain on your wrists. They often come with an over-sized top portion of the handlebar making it more comfortable for you. At least that is the idea!

Choosing the right size road bike can be tricky as they don't all fit the same. Two companies models listed as the same size can have vastly different measurements. Depending on the company, I ride anywhere from a 52 cm to 56 cm frame. All of these have the same length top tube. Don't think that because you ride a given size from one company that you can just get the same size from another and have it fit the same.

When a company lists the size of a road bike frame it is some variation of the length of the seat tube. Measurements all start from the center of the bottom bracket but can be to different points up the seat tube. That point can be the center of the top tube, top of the top tube, top of the seat tube or some virtual point that isn't even on the frame. Add in sloping top tubes and this can get really complicated.
