What the specifications mean
Suspension at both ends means fork and shock setup should be considered together; mismatched sag or rebound can leave the front and rear reacting very differently. Wheel diameter changes with frame size rather than between the front and rear, so the size-specific specification is the one to use for tires, tubes and replacement wheels. The 520% cassette range describes the available gearing more clearly than the component-group name alone.
Suspension setup
Front + rear
Fork and shock pressure, sag and rebound should be balanced and recorded independently.
Wheel system
27.5 / 29 by frame size
Wheel diameter changes with frame size; the record does not indicate a front/rear mismatch.
Gearing
520% cassette range
Calculated from the published 10–52-tooth sprocket span.
Frame material
Carbon / composite
Look for impact damage and clamp marks rather than metal-style dents or rust.
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 and shock were last serviced. Check the stanchions for damage, look for oil at the seals, cycle both units through their travel and test the suspension pivots for play.Evaluate the suspension →
- DrivetrainShift through the full range under light load, measure chain wear and inspect the cassette or freewheel teeth. Skipping or hesitation can indicate wear, poor adjustment or mismatched parts.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
SM geometry
Riding position
The 616 mm stack is tall relative to the 436 mm reach, pointing to a more upright front-end position rather than an especially long, low cockpit. Its 77° effective seat angle places the seated rider relatively forward, a layout that generally helps keep body weight centered on steep climbs.
Handling tendencies
A 64.5° head angle combined with a 1195 mm wheelbase points to strongly stability-oriented 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
The head angle of 64.5° sits somewhat slacker than typical. Its reach of 436 mm sits somewhat longer than typical. The seat angle of 77° sits somewhat steeper than typical.
MD geometry
Riding position
A 456 mm reach paired with 622 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 76.5° effective seat angle places the seated rider relatively forward, a layout that generally helps keep body weight centered on steep climbs.
Handling tendencies
A 64.5° head angle combined with a 1219 mm wheelbase points to strongly stability-oriented 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
The head angle of 64.5° sits somewhat slacker than typical. Its wheelbase of 1219 mm sits somewhat longer than typical. Its reach of 456 mm sits close to the middle of the group.
XM geometry
Riding position
A 478 mm reach paired with 633 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 76.5° effective seat angle places the seated rider relatively forward, a layout that generally helps keep body weight centered on steep climbs.
Handling tendencies
A 64.5° head angle combined with a 1249 mm wheelbase points to strongly stability-oriented 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 reach of 478 mm sits toward the longer end. Its wheelbase of 1249 mm sits toward the longer end. Its stack of 633 mm sits somewhat taller than typical.
LG geometry
Riding position
With 506 mm of reach and 643 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° effective seat angle places the seated rider relatively forward, a layout that generally helps keep body weight centered on steep climbs.
Handling tendencies
A 64.5° head angle combined with a 1286 mm wheelbase points to strongly stability-oriented 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 reach of 506 mm sits toward the longer end. Its wheelbase of 1286 mm sits toward the longer end. Its stack of 643 mm sits toward the taller end.
XL geometry
Riding position
With 540 mm of reach and 654 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 77.5° effective seat angle places the seated rider relatively forward, a layout that generally helps keep body weight centered on steep climbs.
Handling tendencies
A 64.5° head angle combined with a 1329 mm wheelbase points to strongly stability-oriented 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 reach of 540 mm sits toward the longer end. Its wheelbase of 1329 mm sits toward the longer end. Its bottom-bracket drop of 24 mm sits toward the shallower-drop end.
Across the size range
From SM to XL, reach grows by 104 mm and stack by 38 mm, showing how the frame becomes both longer and taller through the published size range. Chainstay length grows from 435 to 440 mm across the range. That size-specific rear-center strategy helps the larger frames grow at both ends instead of adding all of their length ahead of the bottom bracket.
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.
