Randonee & Endurance Riding

The “Long Journey”, a randonee ride tests a rider’s mettle: true endurance, mental fortitude, self-sufficiency, preparation, and mechanical skill. For those that want to learn something new about themselves, complete a brevet de randonneur.

Randonee Models

Axiom XX

The top of the design requirements list for the ideal rando bike includes durability, 24-hour comfort, stable handling, and room for 28c tires and fenders.

Axiom S

Seven’s toughest frame, the Axiom S can take anything the hardest brevet can offer. A more durable frame does not exist. Descend with certainty; roll confidently over the worst gravel roads; the Axiom S will reach the finish eager for more. Sturdy, stable, and smooth, the Axiom S offers the best of all facets of randonneuring.


When specifically designed for randonneuring, Seven’s Expat offers a classic brevet feel and style. We select the tubeset, handling, and rider position for long distance endurance riding: stable, comfortable, and secure—whether it’s the first hour or the 24th. Comfortable confidence is the motto for this steel steed.

Decisions, Decisions

Seven helps you navigate an ever-expanding array of options and accessories to ensure your frame is designed for perfect component compatibility. Here are just a few examples of the breadth of capabilities Seven brings with every frame.



Brakes used to be simple. But options for road and utility bikes now include side pull, long reach, center pull, cantilever, V-brake, 6” disc, 8” disc, 10” disc, low mount disc, or even drum brakes. Seven works with every type of brake system; we can help you make the right decision for your ideal bike.



What drivetrain system is best for your new bike? Again, the answer used to be simple. But with an ever increasing number of drivetrain systems, the choices can be overwhelming. For example, chain or belt drive? One speed or thirty? Derailleur or internally geared hub? Traditional dropouts or sliders? Threaded bottom bracket or BB30? Not only will Seven design your frame for perfect compatibility, regardless of your choice, we can help you decide what’s best for the way you’ll be using your bike, and for the part of the world in which you ride.

Ride Characteristics

Ride Characteristics

Designing the perfect bike is as much about what you can’t see as what you can. Tailoring the precise degree of stiffness or compliance; balancing weight to performance; accommodating the specific demands the bike will face every day. These are achieved through purposefully selected and engineered materials. Tubing diameter, wall thickness, shape, butting, lay-up, even frame geometry all impact the bike’s ride characteristics. This is one of Seven’s specialties and we’re excited to provide your perfect ride.
