Lion of Spring: Allroads Endurance Fit
The Endurance Fit
Optimized for the long ride.
Our Endurance Fit differs from our popular Standard Fit primarily in two dimensions for improved long-distance riding: The front end is higher, and the reach is a bit shorter. This is ideal for rides where comfort, control, and energy management are critical. This fit also excels on rougher roads and dirt; it provides more stability and control with less weight on the front wheel.
Make no mistake, this is still a race-worthy bike. You simply get the benefit of long-distance control and comfort, too.
Positional modifications relative to our popular Standard Fit: Taller and shorter:
- Higher front end: About 3.0 cm taller frame stack means all things equal, the handlebar will sit about 3 cm higher than our Standard Fit. (And 6 cm higher than our Aero Fit.)
- Shorter bar reach: About 1.0 cm shorter frame reach means that, all things equal, the handlebar will be about 1.0 cm closer to the saddle when compared to our Standard Fit. (And about 2 cm shorter than our Aero Fit.)
Bike handling profile: Balanced and predictable. Surefooted. Ideal for a variety of terrain, weather conditions, and tire sizes.
If you love century-plus distances and every kind of road surface, this may be the ideal fit geometry for you.
Looking for a different fit?
We offer the Lion of Spring in two other distinct fit profiles:
Standard Fit
This is our neutral contemporary allroad position. Great for all kinds of performance riding. This fit gets you in a reasonably easy aero position while also supporting comfort on longer outings.
By the numbers:
- Lower front end: About 3.0 cm lower frame stack puts you in a more contemporary allroad position. Cut through the wind while breathing easy.
- About 1.0 cm longer frame reach gets you a bit flatter for all-out efforts.
See the full details and frame geometry for the Standard Fit Lion of Spring.
Aero Fit
Aero position. Watts over comfort. All out speed through tight turns, during acceleration, and climbing. For the full-time rider.
By the numbers:
- Much lower front end: About 6.0 cm lower frame stack puts you in an aggressive aerodynamic position.
- About 2.0 cm longer frame reach provides the flattest back and maximizes aerodynamics. Comfort is a distant second.

General Frame & Bike Geometry Notes
All measurements in centimeters and degrees. Bike geometry shown with 700c x 28 mm slick tires.
- Top tube length is the effective distance from the intersection of the head tube and top tube, measured horizontally to the ground back to the seat tube's centerline.
- Specifications shown with 28 mm tires.
- Seat tube length is measured from the center of the bottom bracket to the intersection of the top tube and seat tube. To determine the total seat tube length — the top edge of the seat top to the center of the bottom bracket — add about 4.5 cm.
- Toe overlap warning: Because toe overlap is determined, in large part, by factors not related to frame geometry, we cannot guarantee that your bike setup will not have any overlap. Make sure you are comfortable with the length of the front center before ordering. You can check your current bike to compare the front center of your sized Seven.
- Standover height is measured midway along the top tube, the typical point where a rider stands on a bike. Seven's standover measurement point is different from many production bikes. Make sure Seven's measurement works for your needs.
- Warning: The popular measurement "frame reach" is not a good gauge of proper bike fit. Also, the term is not accurate and, therefore, often causes confusion. Seven qualifies the term with "BB-HT" to help define the measurement. Regardless of these shortcomings, we include frame reach BB-HT because it has become a popular industry shorthand for comparing one bike size to another. While the frame reach numbers Seven shows here are accurate, Seven does not take responsibility for an ill-fitting bike if you rely on the industry's frame reach number. Top tube length is much more relevant and helpful in bike-to-bike fit comparisons. To better understand the limitations of frame reach, visit our Engineering the Lion page.
- Handlebar width is measured center-to-center at the hoods.
