Road Bike Standover

And swapping out for 27 5 tires seems to be a popular change mountain bike modification.
Road bike standover. Here s how to measure. The bike s actual standover height is the the middle of the top tube. Aim for about one inch of clearance if the bike has a traditional straight. Begin by checking standover height which is the distance between the top tube and your crotch when straddling the bike.
If the bike has a traditional straight top tube that is parallel to the ground you should have approximately 1 of clearance between the ground and tires when you lift the bike as you re straddling it. Just like your pants inseam off the ground increases with platform shoes your bike s standover height will increase if you add bigger tires. You will want at least one inch for a road bike and two inches for a mountain bike. That s why you usually won t see standover height listed on frame specs when components aren t specified.
Compact style frames have low standover but the headtube is roughly the same as a trad bike style. Sportiff style bikes are designed for long endurance rides so come with a higher head tube. Stand over the frame in the center with your feet flat on the floor.
