Supple Road

The Supple Road is the perfect middle ground between our Pure Road and All Road. It is designed with two sets of wheels in mind. We recommend 650b x 42’s for supple, all-road, or gravel use. The smaller wheel size allows for toe clearance with larger tires and/or fenders making a great year-round training bike. But we’ve kept the geometry closer to a Pure Road so you can swap over to 700c wheels making it a true road bike that can take up to 32mm tires. 

Design Priorities

Handling Characteristics

The geometry of the Supple Road is nearly identical to the Pure Road but we raised the bottom bracket slightly and increased tire clearances so it can fit a 700/32 or 650×42. Doing so allowed us to keep the wheelbase short and sporty, and the steering crisp and responsive.


In this day of making the lightest possible bikes, we want you to take comfort in the knowledge that your bike is built to last. We rigorously test our bikes during the design and manufacturing stages to ensure they meet strict international safety standards.


Without compromising ride quality or durability, the Supple Road is light but also durable enough to handle the abuse that rough dirt and gravel roads will throw at it. The Supple Road comes in a “Ride-Tuned” or “Extralite” layup.


The result is a bike that can be both fast and aggressive on paved roads and also gives you the freedom to create new routes and explore. You don’t need to limit yourself to paved rides anymore.

The stiff chassis is perfect for rolling the hills and standing on the climbs. The low bottom bracket gives the ability to corner fast and stick to the ground, inspiring confidence when descending technical roads at high speed.


Details and Geometry – Supple Road

At Pursuit, we make the antithesis of a generic, assembly-line bike. By the time your bike reaches you, only a handful of people have touched it. That level of craftsmanship and attention to detail is what sets Pursuit apart.

Tire Sizes

The Supple Road is optimized for 650bx42’s but also shines with 700c wheels allowing tires up to 32mm.  Rather than slacking out and lengthening the geometry as we have on our All Road, we wanted the Supple Road to be a road race bike with smaller 700c tires and an all-road bike with the larger 650b’s. Tire clearances are 700×32 or 650×42 with fenders and 650×47 without fenders.

Tapered Steerer and IS Headset

We use an Internal Standard (IS) 52/41 headtube for a clean transition between frame and fork. The fork has a 1.250-inch tapered steerer for crisp steering response and sharp handling.

Cable Management

Internal cables with a modular guide system accommodate cables, wires, and hoses. We only include the guides you need for the shift system you select, so there are no unused cable guides.

T-47 Bottom Bracket

We think bottom brackets should be threaded. And we think threads should be metal. So we bonded in a titanium T47 bottom bracket insert. This ensures easy maintenance, prevents squeaking, and fits just about every crank out there.

142×12 Thru-Axle

This is the de facto standard for all high-end bikes. The thru-axle stiffens the chassis and assures that the wheel is always located exactly where it needs to be. We also incorporate a replaceable derailleur hanger and use titanium sleeves in the dropout to reduce wear and protect the paint.

Flat-Mount Brakes

Flat mount brakes give a clean traditional look to a modern system.

Round 27.2 Seatpost

While an aero post may provide a small advantage, we consider comfort a higher priority. We chose to use a round 27.2-mm seatpost for its compliance. We also use a standard external seat clamp because they keep the post in place while avoiding seizure or damage to the frame from over-tightening.


Part of customizing your Pursuit is ride-tuning the perfect layup for you. We tune the layup not only to optimize weight and stiffness but include other considerations such as impact resistance and vibration damping.

We use your goals, priorities, frame size, and bodyweight to balance a smooth ride and vibration reduction with stiffness for out-of-the-saddle efforts without sacrificing comfort when seated.

If you’re a larger rider, hammer, or someone that regularly throws down 1,000-plus watts, we will strategically add material for additional stiffness. If you seek added durability, we will add material to the top tube and seat stays to further strengthen areas that are prone to impacts or damage in a crash.


For you weight weenies out there we offer our Extralite layup. It can dip below 700 grams on smaller, unpainted frames. We build it with a thinner layup of exotic fibers for lightness and stiffness and further shave weight by focusing on the small parts that can add up—cable guides, bottle bosses, etc.

Sizing and Geo

When we designed the Supple Road we wanted to find the middle ground between our Pure Road and All Road. The geometry is the same as the Pure Road but we added tire clearance and raised the bottom bracket ever so slightly so you can run 650b wheels. Learn more about how gravel bikes are designed here.

Custom sizing and geo are available at no extra charge. Contact carl@pursuitcycles if you are interested in custom size or geometry and would like to learn more about what is possible.

Unlike most companies, our sizes are measured by the effective top tube. We do this because it’s the most important measurement on the bike. When comparing our frame sizing to others, be sure to use either the effective top tube length or stack/reach to make sure you are comparing apples to apples.
