How to Properly Set up a Road Bike: Frame Height, Seat Height, Aaddle
A matter of attitude: pain-free road cycling
Your neck hurts on every ride, your butt hurts? You have cramps in your calves? Your body may not be to blame. The trigger for the problems can be your bike or the position in which you sit on your bike. We'll show you which criteria are important when adjusting your bike.
How do I set up my road bike correctly? The frame height
Before we dive into the fine-tuning of the seating position, it is important to ensure that the frame of your racer offers the right height for your body size. Even though you can change the seat height enormously via the seat post, a suitable frame size is important not least because the top tube also gains length with increasing frame heights. The distance from the saddle to the handlebars also increases with growing frame heights, so you need to stretch your upper body further and further. So when people talk about frame heights, they actually mean frame sizes, even though frame sizes are named by height or by the length of the seat tube.
That's almost a little unfair to the top tube, because theoretically the seat tube of your frame could be as short as it wants to be, as long as a seatpost finds a hold in it long enough to serve its inseam length. In terms of the top tube, things look different, which becomes obvious at the latest when the wheels can no longer find room to stand parallel behind each other.
Adjust road bike: Which size fits me?
Whether you sit on a frame that fits your body size, tells you the table "Guidelines". But beware: even if these contents of the table certainly apply to many people, there are always extreme body proportions that fall outside the grid. In such cases, in the "worst" case, only a frame made to measure will help.
A very simple point of reference is also the legroom that a standard frame should offer: Standing with your bare feet on the ground, the top tube of the bike should have at least two to three centimeters of clearance between your legs and your crotch. If their feet barely reach the ground because you are sitting on the top tube, the frame is definitely too big for you.
Which frame height suits me?
The frame height is measured over the distance from the center of the bottom bracket shell to the end of the seat tube (the vertical tube in which the seat post is located) in centimeters.
In the event that you have a frame with a steeply sloping top tube (sloping frame), then you must bring the sloping top tube starting from the connection to the head tube virtually into the horizontal and take the virtual intersection with the seat tube as the measuring point.
Adjustment matter: seat height and saddle
The seat height is the first parameter you need to fix. To do this, set the saddle in a horizontal position and align it lengthwise in line with the top ear.
Sit on the saddle and let both legs hang freely with bare feet. The saddle is at a suitable height when you can still touch the pedal, which is horizontal at the bottom dead center of the crank, with your heel bone.
Road bike: How do you determine your seat height?
A more scientific method offers the equation "stride length x 0.885 = saddle height".
No matter which method you choose, your seat height depends on more than just your leg length. Pedaling coordination, stretch condition, or personal preference may cause you to fine-tune the saddle beyond our procedures. Ultimately, the individually perfect saddle height is determined by you.
What do I have to pay attention to when adjusting the saddle?
After you have adjusted the saddle to the correct height, you must also adjust the saddle horizontally. Sit on the saddle and adjust the crank arms to horizontal balance.
Place your foot on the front pedal. If you can drop a perpendicular through the kneecap of your leg and the ball of your big toe, the saddle is positioned correctly. If not, move the saddle braces forward or backward in the post head. Also in this case, the perpendicular at the kneecap is the starting point for an initial adjustment.
Road bike: The right distance between saddle and handlebars.
The optimal seating position depends not only on sitting. You also have to hold the handlebars, so you need a suitable distance to the same.
Grasp the handlebars in the bend, one foot is in the pedal, the entsrpechende crank arm staht paralell to the down tube. Elbow and kneecap should now have about two centimeters distance from each other, so the elbow can swing freely through. If this is not the case or if the distance is too great, you should choose a shorter or longer stem.
