Details and Geometry – Pure 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 Clearance

This is no “Gravel Grinder,” but we recognize the trend toward larger tires. Although counter-intuitive, larger tires are faster. They roll smoother and produce less wasted energy. They are more comfortable on long days and they grip better in turns. The Pure Road can comfortably fit 28-mm tires and  in some cases even larger, depending on the tire and rim combo.

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 1.5-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 road 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.

Ride-Tuned 

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.

Extralite

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

Custom sizing and geo are available. 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.
