Used-frameset inspection
If you’re buying this frameset used
Before buying: confirm the serial number and exact model, inspect frame and fork alignment, and inventory every included axle, hanger, clamp, headset part, cable guide and proprietary fitting.
Inspect the frame and fork →- FrameCheck paint chips, vent holes and the inside of the seat tube for corrosion. Also look for dents, bent tubes and cracking around welded or brazed joints.Inspect the frame and fork →
- Included hardwareInventory every axle, hanger, clamp, headset part, cable guide, frame plug and proprietary fitting included with the frameset. Confirm replacement availability before treating a missing small part as insignificant.
- AlignmentSight along the frame and fork from several directions. Confirm that the fork, rear dropouts, head tube and other visible interfaces appear straight; professional measurement is appropriate when alignment cannot be established visually.

Geometry interpretation
What this geometry means
Small geometry
Riding position
The 593 mm stack is tall relative to the 404 mm reach, pointing to a more upright front-end position rather than an especially long, low cockpit. The 73° effective seat angle is comparatively relaxed for a modern mountain bike, placing the seated position farther behind the bottom bracket than a steep climbing-oriented layout.
Handling tendencies
A 69° head angle combined with a 1087 mm wheelbase points to quicker-steering and more responsive steering and chassis behavior. The longer the chassis and slacker the front end, the more the bike tends to favor composure over very quick direction changes.
Medium geometry
Riding position
The 602 mm stack is tall relative to the 426 mm reach, pointing to a more upright front-end position rather than an especially long, low cockpit. The 73° effective seat angle is comparatively relaxed for a modern mountain bike, placing the seated position farther behind the bottom bracket than a steep climbing-oriented layout.
Handling tendencies
A 69° head angle combined with a 1113 mm wheelbase points to quicker-steering and more responsive steering and chassis behavior. The longer the chassis and slacker the front end, the more the bike tends to favor composure over very quick direction changes.
Large geometry
Riding position
A 448 mm reach paired with 612 mm of stack gives this size a moderate frame proportion: roomy enough when standing without pushing strongly toward either a very low or very upright front end. The 73° effective seat angle is comparatively relaxed for a modern mountain bike, placing the seated position farther behind the bottom bracket than a steep climbing-oriented layout.
Handling tendencies
A 69° head angle combined with a 1138 mm wheelbase points to quicker-steering and more responsive steering and chassis behavior. The longer the chassis and slacker the front end, the more the bike tends to favor composure over very quick direction changes.
X-Large geometry
Riding position
A 470 mm reach paired with 621 mm of stack gives this size a moderate frame proportion: roomy enough when standing without pushing strongly toward either a very low or very upright front end. The 73° effective seat angle is comparatively relaxed for a modern mountain bike, placing the seated position farther behind the bottom bracket than a steep climbing-oriented layout.
Handling tendencies
A 69° head angle combined with a 1164 mm wheelbase points to quicker-steering and more responsive steering and chassis behavior. The longer the chassis and slacker the front end, the more the bike tends to favor composure over very quick direction changes.
Across the size range
From Small to X-Large, reach grows by 66 mm and stack by 28 mm, showing how the frame becomes both longer and taller through the published size range. The rear center stays essentially constant at about 435 mm across sizes, so most of the wheelbase growth happens in the front half of the bike rather than by lengthening the rear triangle.
Geometry describes frame proportions and likely tendencies, not a ride test. Rider proportions, cockpit setup, tires, suspension settings, wheel configuration, and component choices can materially change how a bicycle fits and feels.
