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 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 + rear
Fork and shock pressure, sag and rebound should be balanced and recorded independently.
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 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 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 paired manufacturer values. Velopedia separates the numerically higher and lower chassis states for interpretation without treating them as separate bicycles.
XS geometry
Configuration
Riding position
The 601 mm stack is tall relative to the 410 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 65.1° head angle combined with a 1156 mm wheelbase points to 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 435 mm sits somewhat longer than typical. Its wheelbase of 1156 mm sits somewhat longer than typical.
Riding position
The 603 mm stack is tall relative to the 407 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 64.8° head angle combined with a 1156 mm wheelbase points to 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
The seat angle of 77.3° sits toward the steeper end. The chainstay of 435.5 mm sits somewhat longer than typical. The head angle of 64.8° sits somewhat slacker than typical.
S geometry
Configuration
Riding position
The 610 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.
