What to Do if You Are Between BMC Sizes?
If your height falls squarely on the borderline between two sizes for the BMC Roadmachine (Carbon), don’t panic. This is a normal occurrence in bike geometry. Here is how to decide which way to go:
Choosing the smaller option gives you a shorter reach to the handlebars, creating a more upright riding position. Opting for the larger frame extends the wheelbase, delivering a highly stable ride at high speeds.
How to Measure Your Height for an Accurate Fit
Don’t guess your height when investing in a new bike. For the most accurate measurement, take off your shoes and stand with your back entirely flat against a wall. Look straight ahead, place a book flat on top of your head, mark the wall, and measure the distance to the floor. Use a flat-edged object or book resting horizontally on your head to mark the point accurately against the wall before running a tape measure to the floor.
