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. The mixed-wheel layout uses different front and rear diameters, so tires, tubes, rims and spare wheels are not interchangeable end to end. 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
Mixed 29 / 27.5
Front and rear tires, tubes, rims and spare wheels use different diameters.
Drivetrain
Electronic · 520% range
Shift-system battery state joins derailleur setup and sprocket compatibility as a troubleshooting variable.
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 →
- 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.Check wheels and tires →

Geometry interpretation
What this geometry means
The archived table contains paired manufacturer values. Velopedia separates the numerically higher and lower chassis states for interpretation without treating them as separate bicycles.
S geometry
Configuration
Riding position
The 623 mm stack is tall relative to the 435 mm reach, pointing to a more upright front-end position rather than an especially long, low cockpit. Its 77.6° effective seat angle places the seated rider relatively forward, a layout that generally helps keep body weight centered on steep climbs.
Handling tendencies
A 64.2° head angle combined with a 1208 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.
Configuration changes
Compared with Lower geometry, this configuration raises the bottom bracket by 3 mm, reduces bottom-bracket drop by 3 mm, steepens the head angle by 0.3°, and extends reach by 3 mm.
Archive context
The seat angle of 77.6° sits toward the steeper end. The chainstay of 437 mm sits somewhat longer than typical. Its stack of 623 mm sits somewhat taller than typical.
Riding position
The 625 mm stack is tall relative to the 432 mm reach, pointing to a more upright front-end position rather than an especially long, low cockpit. 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 63.9° head angle combined with a 1208 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.
Configuration changes
Compared with Higher geometry, this configuration lowers the bottom bracket by 3 mm, increases bottom-bracket drop by 3 mm, slackens the head angle by 0.3°, and shortens reach by 3 mm.
Archive context
Its stack of 625 mm sits toward the taller end. The head angle of 63.9° sits toward the slacker end. The chainstay of 437 mm sits somewhat longer than typical.
M geometry
Configuration
Riding position
A 460 mm reach paired with 632 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 77.9° effective seat angle places the seated rider relatively forward, a layout that generally helps keep body weight centered on steep climbs.

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.
