Velopedia analysis
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. 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. Electronic shifting removes the usual shift cable but adds a separate battery and controls, while the 520% cassette range describes how much gearing is available.
Suspension setup
Front + rear
Fork and shock pressure, sag and rebound should be balanced and recorded independently.
Wheel system
27.5 / 29 options
Both diameters are documented, but the archive does not prove a mixed front/rear setup.
Drivetrain
Electronic · 520% range
Shift-system battery state joins derailleur setup and sprocket compatibility as a troubleshooting variable.
Brake service
Hydraulic disc
Pad and rotor condition plus the correct bleed fluid are the primary service checks.
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 →
- BrakesBoth levers should feel firm and return cleanly. Check for fluid around the levers and calipers, inspect pad thickness and contamination, and look for worn or bent rotors.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 →
- DrivetrainConfirm every shift-system battery charges, every shift control works and the derailleur moves cleanly across the cassette. Make sure the matching shift-system charger is included, then measure chain wear and inspect the cassette teeth.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. If it is set up tubeless, confirm both tires hold pressure and ask when the sealant was last refreshed.Check wheels and tires →

Geometry interpretation
What this geometry means
S1 geometry
Riding position
The 611 mm stack is tall relative to the 400 mm reach, pointing to a more upright front-end position rather than an especially long, low cockpit. Its 77.7° effective seat angle places the seated rider relatively forward, a layout that generally helps keep body weight centered on steep climbs.
Handling tendencies
The manufacturer lists 133 mm of trail. More trail generally increases self-centering and stability, while less trail generally makes steering respond more quickly to rider input. 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.
Archive context
Its reach of 400 mm sits toward the shorter end. The seat angle of 77.7° sits toward the steeper end. Its stack of 611 mm sits somewhat taller than typical.
S2 geometry
Riding position
The 621 mm stack is tall relative to the 420 mm reach, pointing to a more upright front-end position rather than an especially long, low cockpit. 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
The manufacturer lists 134 mm of trail. More trail generally increases self-centering and stability, while less trail generally makes steering respond more quickly to rider input.
Archive context
Its reach of 420 mm sits toward the shorter end. Its trail of 134 mm sits somewhat higher than typical. Its stack of 621 mm sits somewhat taller than typical.
S3 geometry
Riding position
The 630 mm stack is tall relative to the 445 mm reach, pointing to a more upright front-end position rather than an especially long, low cockpit. 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
The manufacturer lists 134 mm of trail. More trail generally increases self-centering and stability, while less trail generally makes steering respond more quickly to rider input.
Archive context
Its reach of 445 mm sits toward the shorter end. Its trail of 134 mm sits somewhat higher than typical. Its stack of 630 mm sits somewhat taller than typical.
S4 geometry
Riding position
A 470 mm reach paired with 644 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° effective seat angle places the seated rider relatively forward, a layout that generally helps keep body weight centered on steep climbs.
Handling tendencies
The manufacturer lists 134 mm of trail. More trail generally increases self-centering and stability, while less trail generally makes steering respond more quickly to rider input.
Archive context
Its stack of 644 mm sits toward the taller end. Its reach of 470 mm sits toward the shorter end. Its trail of 134 mm sits somewhat higher than typical.
S5 geometry
Riding position
A 495 mm reach paired with 658 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° effective seat angle places the seated rider relatively forward, a layout that generally helps keep body weight centered on steep climbs.
Handling tendencies
The manufacturer lists 134 mm of trail. More trail generally increases self-centering and stability, while less trail generally makes steering respond more quickly to rider input.
Archive context
Its stack of 658 mm sits toward the taller end. The chainstay of 445 mm sits toward the longer rear-center end. Its reach of 495 mm sits somewhat shorter than typical.
S6 geometry
Riding position
With 525 mm of reach and 671 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 76° effective seat angle places the seated rider relatively forward, a layout that generally helps keep body weight centered on steep climbs.
Handling tendencies
The manufacturer lists 134 mm of trail. More trail generally increases self-centering and stability, while less trail generally makes steering respond more quickly to rider input.
Archive context
Its stack of 671 mm sits toward the taller end. Its reach of 525 mm sits somewhat longer than typical. The seat angle of 76° sits somewhat more relaxed than typical.
Across the size range
From S1 to S6, reach grows by 125 mm and stack by 60 mm, showing how the frame becomes both longer and taller through the published size range. Chainstay length grows from 430 to 445 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.
