Not all gravel bikes are built for the same kind of rider. Some riders need a bike that fits naturally into their everyday routines, while others want speed across mixed surfaces, and some are planning long routes with bags, gear, and unpredictable terrain ahead. Each of those riding styles asks for a different approach to design.
That’s where Polygon gravel bikes stand apart. Instead of relying on a single platform to cover every scenario, Polygon develops distinct gravel models with clear intentions. Frame geometry, riding position, mounting options, and handling characteristics are all shaped around how the bike will actually be used.
In this comparison, we’ll examine three gravel models with distinctly different personalities and purposes. Let’s check it out!
Main Differences Between Polygon Path X, Tambora, and Bend
Within the lineup of Polygon gravel bikes, Path X, Tambora, and Bend are not variations of the same idea. Each model is developed around a distinct riding purpose, with differences that go beyond components.
1. Polygon Path X: Urban Adventure, Everyday Gravel
We designed the Polygon Path X as the most accessible gravel bike for everyday riding. Positioned as an urban adventure gravel bike, Path X is built for riders who regularly move between paved roads, city streets, and light gravel paths.
Its character is defined by:
- A balanced, neutral geometry that delivers comfort and predictable handling for daily use
- Practical versatility for commuting, fitness riding, and short escapes onto gravel routes
- A setup that prioritizes efficiency and control rather than aggressive off-road capability
For us, Path X represents a true do-everything daily bike. It is ideal for riders who want gravel flexibility without stepping into touring-focused geometry or heavier adventure setups. Compared to the other two models, Path X is the most city-friendly and the least specialized for extreme terrain.
2. Polygon Tambora: Speed-Focused Gravel with Adjustable Geometry
The Polygon Tambora is developed with a clear focus on speed and efficiency across mixed surfaces. Tambora is intended for riders who value pace and performance, even when road conditions change.
What sets Tambora apart:
- Flip-chip geometry adjustment that allows riders to fine-tune handling and riding position
- A more performance-oriented gravel platform, suited for fast gravel, paved roads, and long mixed-terrain rides
- A riding character that leans toward all-road and race-inspired gravel, rather than relaxed touring
Tambora is well suited for day rides, fast gravel routes, and light touring, particularly for riders who enjoy covering distance at higher speeds. While it supports mounting options, its primary focus remains efficiency and responsiveness rather than heavy load carrying.
3. Polygon Bend: Adventure Gravel for Long Distance and Load
The Polygon Bend series is the most adventure-focused gravel platform in our lineup. It is designed for riders who prioritize distance, durability, and rougher terrain over outright speed.
Core characteristics of the Bend include:
- Geometry that emphasizes stability and comfort, especially during long hours in the saddle
- Greater suitability for wider tires, improving traction and control on rough gravel
- A design intended to support loaded riding, making it suitable for touring, bikepacking, and extended routes
Compared to Path X and Tambora, Bend adopts a more upright riding position and a calmer handling profile. It is the bike for riders who expect unpredictable surfaces, carry heavier gear, and combine off-road and on-road conditions over long-distance journeys.
Geometry & Riding Position Differences
Polygon Path X Gravel Bike
The Path X features a geometry that’s balanced and approachable, not overly stretched forward nor too upright. It’s designed to feel comfortable for daily riding and general mixed terrain use without forcing an aggressive racing posture. The headtube angle and stack/reach are tuned to support confidence at varied speeds, especially on city streets and light gravel.
Polygon Tambora Gravel Bike
The Tambora is distinct for its flip-chip geometry feature. This officially allows riders to switch between two positions:
- Long mode for more stability and comfort across longer rides and rougher surfaces
- Short mode for a slightly more responsive, quicker riding feel
This setup subtly adjusts wheelbase and headtube angle, changing how the bike handles without a complete redesign. With tires up to ~45 mm clearance, Tambora strikes a good balance between speed and control.
Polygon Bend Gravel Bike
Bend’s geometry prioritizes stability and comfort for gravel adventures and longer distances. While the official site emphasizes its capability with wider tires (up to ~50c on many builds) and comfortable handling, the actual positioning leans more upright compared to Tambora’s performance orientation. Wider tire clearance and a lengthened wheelbase contribute to confidence when fully loaded and on rough surfaces.
Storage Capacity & Gear Mounting
Polygon Path X Gravel Bike
Path X includes practical mounting points suitable for everyday riding needs, such as mounts for fenders, a rear rack, and perhaps a frame bag, geared toward utility and commuting versatility. However, it’s not specifically marketed for heavy bikepacking loads like Bend.
Polygon Tambora Gravel Bike
The Tambora lineup officially includes 14 universal mounting points across the frame: 3 on the top tube, 7 on the down tube, 2 on the seat tube, and 2 for a rear carrier. These are designed so riders can attach frame bags or other gear without needing proprietary mounts, a blend of performance and touring capability. Tambora also supports rear mudguard and carrier installation.
Polygon Bend Gravel Bike
The Bend V series, such as the Bend V9X, offers a versatile setup for bikepacking and long tours with 10 mounting points placed on the frame’s top tube, down tube, and other bag/bottle bosses that are compatible with universal-size mounts.
These attachment points support frame bags, water bottle cages, and bikepacking gear, and the bike also allows for rear pannier and accessory installations, making it adventure-ready without compromising stability and handling.
Drivetrain & Braking System Differences
Polygon Path X Gravel Bike
Specifications for Path X generally feature reliable gravel/touring-ready drivetrains (often 2× setups with practical gear range) and hydraulic disc brakes for consistent stopping power in rain or gravel terrain. It’s designed more for stable usability than maximum climbing range or extreme gearing.
Polygon Tambora Gravel Bike
Tambora builds reflect gravel performance drivetrain options, ranging from SRAM Rival XPLR AXS wireless 12-speed (on higher tiers) to mechanical gravel setups on lower tiers. Brake systems across the range are hydraulic disc, typically with rotor sizes up to 160 mm for confident braking at higher gravel speeds.
Polygon Bend Gravel Bike
The Bend series shows a wide variability of drivetrain configurations depending on model, from SRAM Apex 1 11-speed up to higher-end GX Eagle AXS 12-speed, reflecting its capability to take on steep, loaded terrain. Brake systems are also hydraulic discs, providing control with heavier loads or rough ground.
What Reviews Say?
