Both bikes use Polygon’s ALX gravel frame with a tapered head tube and full-carbon fork. This combination strikes a balance between stiffness and compliance: aluminium offers durability and value, while carbon helps absorb vibrations and reduces weight【745617510422842†L109-L159】. The geometry sits between road and mountain bikes. A slack head tube angle around 70–72° and a longer wheelbase provide stability on loose gravel, while a relatively steep seat tube keeps the rider centred for efficient pedalling【196774589580374†L75-L82】. Generous tyre clearance allows up to 45 mm tyres, so you can choose slicks for fast road rides or knobbier rubber for off-road adventures. Rack and fender mounts make the Path series bikepacking-friendly, and internal cable routing keeps the bike looking tidy.

The Path X4 is built around a 2×10 drivetrain, typically Shimano Tiagra, giving a wide range of gears for climbs and fast descents. Mechanical disc brakes provide dependable stopping power and are easy to service. The wheels are tubeless-ready 700c rims paired with 35 mm tyres out of the box. For riders who want a more modern setup, the Path X5 swaps to a 1×11 drivetrain with a clutch rear derailleur for better chain retention. It also features hydraulic disc brakes for improved modulation and reduced hand fatigue. Both bikes use flared drop bars for control on rough terrain and comfortable endurance saddles.

On mixed surfaces, the Path series feels composed and efficient. The slightly slack head angle and longer wheelbase inspire confidence when descending loose gravel roads, while the responsive front end keeps steering precise. The carbon fork smooths out buzz from washboard sections, and the frame’s stiffness helps you accelerate quickly. The X4’s 2× drivetrain offers small gear jumps, which is great for riders who split time between road and trail. The mechanical brakes require more hand force but are easy to maintain. The X5’s 1× setup simplifies shifting and reduces maintenance, though you may miss the high or low extremes of a double chainring. Its hydraulic brakes deliver strong, consistent stopping power in all conditions.

If you’re on a tighter budget or prefer the familiarity of a double chainring, the Path X4 is a great entry into gravel riding. It delivers solid performance for commuting, fitness rides and light bikepacking. Riders willing to spend a bit more will appreciate the X5’s simplified 1× drivetrain and hydraulic brakes, especially if you tackle steeper terrain or ride year-round in wet weather.

Polygon’s Path X4 and X5 bring gravel versatility to the masses. With comfortable, stable geometry, ample tyre clearance and thoughtful mounts for racks and fenders, these bikes can double as commuters, adventure rigs and weekend explorers. The X5’s modern drivetrain and braking system make it the standout if your budget allows, but both models offer tremendous value thanks to Polygon’s direct-to-consumer pricing【475249501394961†L90-L149】.
