What size road bike?

Question

I am 5' 7'' tall. I ride a 17'' mountain bike and was wondering what size road bike I should buy

Answer 1

Road bikes are measured in Centimeters.  Unfortunately, you cannot just convert your mountain bike measurement in inches to cm.    Here's a link to get you started; you really need to visit a good bike shop to get fitted properly.

Answer 2
