Velopedia analysis
What the specifications mean
Suspension is concentrated at the fork, so fork setup and rear-tire pressure are the main tools for balancing front and rear behavior. Both 27.5- and 29-inch wheels appear in the record, but it does not establish a mixed front/rear build; confirm the correct diameter for the selected frame size. The 520% cassette range describes the available gearing more clearly than the component-group name alone.
Suspension setup
Front only
Fork settings affect the front while rear-wheel behavior remains dependent on tire and wheel setup.
Wheel system
27.5 / 29 options
Both diameters are documented, but the archive does not prove a mixed front/rear setup.
Gearing
520% cassette range
Calculated from the published 10–52-tooth sprocket span.
Frame material
Aluminum / alloy
Dents and cracking around welds, pivots and loaded junctions deserve attention.
Used-bike inspection
If you’re buying this bike used
Before any test ride: both brakes should stop the bike firmly and release cleanly; both wheels should run true and be securely attached; tires should have no casing damage; and the headset, handlebar, stem, cranks and pedals should have no looseness or play.
Follow the full used-bike inspection order →- FrameLook closely for dents and hairline cracks around welds, the head tube and bottom-bracket area. Cosmetic scratches matter less than a change in shape or a crack line.Inspect the frame and fork →
- BrakesTest each brake separately and confirm it stops firmly and releases cleanly. Inspect the pads and braking surfaces for wear or contamination, and check the cables or hoses for damage.Inspect the brakes →
- SuspensionAsk when the fork was last serviced. Check the stanchions for damage, look for oil at the seals and make sure the fork moves smoothly without bushing play.Evaluate the suspension →
- DrivetrainShift through every gear under light load and measure chain wear. Confirm that the shifter, derailleur, chain and cassette belong to the same 12-speed system.Check drivetrain wear →
- Wheels & tiresSpin both wheels and watch the rims for side-to-side or vertical movement. Check for dents, cracks, loose or uneven spokes and hub play, then inspect both tire casings for cuts, cracking or exposed threads.Check wheels and tires →

Geometry interpretation
What this geometry means
X-Small geometry
Riding position
The 599 mm stack is tall relative to the 410.7 mm reach, pointing to a more upright front-end position rather than an especially long, low cockpit.
Handling tendencies
A 66.4° head angle combined with a 1137 mm wheelbase points to fairly neutral for modern mountain handling 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.
Archive context
Its bottom-bracket drop of 56.6 mm sits toward the deeper-drop end. The chainstay of 437 mm sits toward the longer rear-center end. The head angle of 66.4° sits somewhat steeper than typical.
Small geometry
Riding position
A 433.6 mm reach paired with 599 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.
Handling tendencies
A 66.4° head angle combined with a 1159.5 mm wheelbase points to fairly neutral for modern mountain handling 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.
Archive context
Its bottom-bracket drop of 56.6 mm sits toward the deeper-drop end. The chainstay of 437 mm sits somewhat longer than typical. The head angle of 66.4° sits somewhat steeper than typical.
Medium geometry
Riding position
A 453.6 mm reach paired with 607.4 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.
Handling tendencies
A 66.4° head angle combined with a 1181.5 mm wheelbase points to fairly neutral for modern mountain handling 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.
Archive context
Its bottom-bracket drop of 56.6 mm sits toward the deeper-drop end. The head angle of 66.4° sits somewhat steeper than typical. Its wheelbase of 1181.5 mm sits somewhat shorter than typical.
Large geometry
Riding position
With 475.5 mm of reach and 613.5 mm of stack, the frame has a relatively long, low proportion that should leave plenty of room when standing and put the front end toward the lower side of modern mountain-bike fit.
Handling tendencies
A 66.4° head angle combined with a 1197.5 mm wheelbase points to fairly neutral for modern mountain handling 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.
Archive context
Its stack of 613.5 mm sits toward the lower end. Its bottom-bracket drop of 56.6 mm sits toward the deeper-drop end. Its wheelbase of 1197.5 mm sits toward the shorter end.
X-Large geometry
Riding position
With 492.6 mm of reach and 625.5 mm of stack, the frame has a relatively long, low proportion that should leave plenty of room when standing and put the front end toward the lower side of modern mountain-bike fit.

A 66.4° head angle combined with a 1228.7 mm wheelbase points to fairly neutral for modern mountain handling 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.
Archive context
Its stack of 625.5 mm sits toward the lower end. Its reach of 492.6 mm sits toward the shorter end. Its bottom-bracket drop of 56.6 mm sits toward the deeper-drop end.
Across the size range
From X-Small to X-Large, reach grows by 81.9 mm and stack by 26.5 mm, showing how the frame becomes both longer and taller through the published size range. The rear center stays essentially constant at about 437 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.
