The geometry
Many people look at a bike especially on the weight. Others on the equipment. Also the frame height is an issue. Size M? Or rather size L?
Few people are interested in the details of the geometry when they are interested in a bike. Some details are more important for the riding character of a bike than the equipment or the weight.
With geometry, it's not a case of either/or. It's not like choosing between two colors. A geometry is the sum of many small details. You have to imagine it like a song. It consists of many different notes. The bike is the song, the geometry details are the notes. Only when everything works together perfectly will it be a hit. We have meticulously developed the geometry of THE SUPERFAST. It is designed to give the bike an agile yet comfortable character. We explain the most important parameters.
REACH
The reach is an important value for the riding character and the seating position. It determines how compact or stretched the rider sits. The higher the reach value, the more stretched you sit.
THE SUPERFAST offers the perfect balance. The reach is chosen so that the seating position is sporty but not stretched. This makes it possible to cover long distances comfortably.
The fine adjustment is made via the length of the stem. Racers can achieve maximum aerodynamics and efficiency with a long stem. Relaxed riders benefit from more comfort with a shorter stem.
However, the seating position also depends on the so-called stack value.
STACK
This value indicates how high the handlebars are positioned. High stack = high handlebars. Low stack = low handlebars. Even if the reach is high, a large stack value can counteract a stretched position. The opposite is also true. Bikes with a low handlebar position can be comfortable if the distance from the rider to the handlebars (reach) is small.
It is the interaction of reach and stack that determines the riding position. Finding the perfect ratio is the great art. THE SUPERFAST's stack-to-reach value is within the normal range for sporty gravel bikes. It supports the sporty, comfortable riding position.
STEERING ANGLE
This value has a significant influence on the steering behavior, i.e. the handling of the bike. A flat steering angle ensures a smooth ride. At least as long as you're going straight. It's a disadvantage in tight corners. If the steering angle is too steep, the result is nervous handling. THE SUPERFAST is designed to be agile without being nervous in corners. The steering angle is therefore steep, as is typical for racing bikes, but within the normal range.
SEAT ANGLE
The seat angle influences the seating position, as the name suggests. But power transmission also depends on it. The steeper the seat angle, the more efficient the pedalling. That's the rough formula. But if you sit too far forward, traction at the rear wheel suffers. This can lead to poor cornering.
The seat angle of THE SUPERFAST is therefore designed to optimize power transmission while distributing the rider's weight as evenly as possible over both wheels. This ensures good traction in all situations. Uphill. Downhill. And in corners.
WHEELBASE
Do you want the bike to roll well in a straight line? Or do you want it to be as agile as possible? The wheelbase has a significant influence on this. THE SUPERFAST is designed to be balanced to ride, which is why the value is exactly at the intersection of agility and stability.
BOTTOM BRACKET OFFSET
A low bottom bracket means a low center of gravity, which is optimal for traction and control of the bike. At 278 millimeters, the bottom bracket position of THE SUPERFAST is quite low. The bottom bracket drop is 75 millimeters. The center of gravity is therefore as low as possible. Nevertheless, there is enough ground clearance to prevent the frame and cranks from touching the ground. THE SUPERFAST is designed for tires up to 50 millimeters wide. This is taken into account in the bottom bracket height.
CHAINSTAY LENGTH
The length of the chainstays affects the temperament of the bike. Long chainstays ensure good directional stability. Short chainstays make cornering easier. The well-balanced chainstays of THE SUPERFAST guarantee riding fun in twisty terrain and on straight gravel roads.
SEAT TUBE LENGTH:
The length of the seat tube determines how long the seat post is. Long seat posts flex more than shorter ones, which has a positive effect on comfort. The seat tube of THE SUPERFAST is classically long. This looks elegant and creates space in the frame triangle for frame bags. The flex of the seat post offers noticeable comfort despite the medium extension length.
The geometry table shows all the details. We will explain how to determine the right frame height for you in one of the next posts.
