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. The 510% cassette range describes the available gearing more clearly than the component-group name alone. Carbon construction changes the inspection emphasis from metal-style dents and corrosion to impact damage, ripples and overtightened clamp areas.
Suspension setup
Front only
Fork settings affect the front while rear-wheel behavior remains dependent on tire and wheel setup.
Gearing
510% cassette range
Calculated from the published 10–51-tooth sprocket span.
Frame material
Carbon / composite
Look for impact damage and clamp marks rather than metal-style dents or rust.
Wheel standard
29 in · 622 mm
Rim width and frame or fork clearance remain important beyond nominal diameter.
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 →- FrameInspect the frame in bright light, especially around the head tube, bottom bracket, chainstays and clamped areas. Look for cracks, ripples, crushed sections or signs of a previous impact.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
The archived table contains multiple manufacturer geometry states. Velopedia preserves source order and analyzes each state separately rather than averaging the published values.
X-Small geometry
Configuration
Riding position
A 435 mm reach paired with 589.3 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. Its 77.3° effective seat angle places the seated rider relatively forward, a layout that generally helps keep body weight centered on steep climbs.
Handling tendencies
A 66.3° head angle combined with a 1157 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. A 430 mm rear center is compact, which tends to make rear-wheel weight shifts and tight direction changes easier than a long-rear-center layout.
Configuration changes
Compared with Configuration 2, this configuration steepens the head angle by 0.3°.
Archive context
Its reach of 435 mm sits toward the longer end. The seat angle of 77.3° sits somewhat steeper than typical. Its stack of 589.3 mm sits somewhat lower than typical.

Handling tendencies
A 66° head angle combined with a 1157 mm wheelbase points to stability-oriented steering and chassis behavior.

Medium geometry
Configuration
Riding position
With 470 mm of reach and 607.6 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. Its 77.3° effective seat angle places the seated rider relatively forward, a layout that generally helps keep body weight centered on steep climbs.
