Velopedia analysis
What the specifications mean
The 510% cassette range describes the available gearing more clearly than the component-group name alone. The rims and tires are tubeless-ready, but that label does not confirm the bike is currently set up without tubes; tape, valves, sealant and tire condition still matter. Carbon construction changes the inspection emphasis from metal-style dents and corrosion to impact damage, ripples and overtightened clamp areas.
Gearing
510% cassette range
Calculated from the published 10–51-tooth sprocket span.
Tire setup
Tubeless-ready
The rims and tires may support tubeless use, but the bike may still be running tubes.
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 →
- 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. 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
X-Small geometry
Riding position
The 601.8 mm stack is tall relative to the 373.7 mm reach, leaving room for a more upright, relaxed gravel position. A 75° seat angle puts the rider relatively forward over the bottom bracket, shortening the effective seated reach compared with a more relaxed seat angle.
Handling tendencies
A 67° head angle combined with a 1094.4 mm wheelbase points to calm and 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. The 445 mm chainstay is on the longer side for a drop-bar chassis, generally favoring stability and tire/heel clearance over an especially compact rear end.
Archive context
Its wheelbase of 1094.4 mm sits toward the longer end. The head angle of 67° sits toward the slacker end. Its stack of 601.8 mm sits toward the taller end.
Small geometry
Riding position
A 398.7 mm reach and 601.8 mm stack give this size a middle-ground gravel proportion: neither especially stretched and low nor unusually upright. A 75° seat angle puts the rider relatively forward over the bottom bracket, shortening the effective seated reach compared with a more relaxed seat angle.
Handling tendencies
A 67° head angle combined with a 1119.4 mm wheelbase points to calm and 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. The 445 mm chainstay is on the longer side for a drop-bar chassis, generally favoring stability and tire/heel clearance over an especially compact rear end.
Archive context
The head angle of 67° sits toward the slacker end. Its wheelbase of 1119.4 mm sits toward the longer end. Its stack of 601.8 mm sits toward the taller end.
Medium geometry
Riding position
A 417.6 mm reach and 624.8 mm stack give this size a middle-ground gravel proportion: neither especially stretched and low nor unusually upright. A 75° seat angle puts the rider relatively forward over the bottom bracket, shortening the effective seated reach compared with a more relaxed seat angle.

A 67° head angle combined with a 1203.7 mm wheelbase points to calm and 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. The 445 mm chainstay is on the longer side for a drop-bar chassis, generally favoring stability and tire/heel clearance over an especially compact rear end.

The head angle of 67° sits toward the slacker end. The seat angle of 75° sits toward the steeper end. Its wheelbase of 1203.7 mm sits toward the longer end.
Across the size range
From X-Small to X-Large, reach grows by 84 mm and stack by 59.9 mm, showing how the frame becomes both longer and taller through the published size range. The rear center stays essentially constant at about 445 mm across sizes, so most of the wheelbase growth happens in the front half of the bike rather than by lengthening the rear triangle.
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.
