What to Do if You Are Between BMC Sizes?
If your height falls squarely on the borderline between two sizes for the BMC Kaius (Performance Gravel), 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
To ensure the sizing data coordinates properly with the matrix above, avoid relying on your standard shoe size or an old doctor’s appointment estimate. Take a fresh measurement by removing your footwear, standing flat with your heels against a level baseboard, and ensuring your posture is entirely straight. 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.
