Mountain Bike Fit Tip: When sizing a mountain bike like this, standover height is crucial. You want at least 2-3 inches of clearance between you and the top tube for sudden dismounts on technical terrain. Remember that suspension sag (usually 20-30%) will slightly lower the bike once you are seated.
What to Do if You Are Between Marin Sizes?
It is incredibly common to find your exact height overlapping between two different Marin Aggressive Hardtail MTB (San Quentin) frame dimensions. When this happens, your riding style and physical proportions should dictate your choice:
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.
