What the specifications mean
Electronic shifting removes the usual shift cable but adds a separate battery and controls, while the 300% cassette range describes how much gearing is available. A disc-brake label alone does not establish parts compatibility; rotor diameter, mount standard and pad shape still need confirmation. 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.
Drivetrain
Electronic · 300% range
Shift-system battery state joins derailleur setup and sprocket compatibility as a troubleshooting variable.
Brake compatibility
Disc brake system
Rotor diameter, mount standard and pad shape still require confirmation before replacement.
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.
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 brakes should stop firmly and release without rubbing. Inspect pad thickness, rotor wear and alignment, and check the cables or hoses for damage.Inspect the brakes →
- 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 →
- Bottom bracketTurn the cranks slowly, feel for rough bearings and check for side-to-side play. Creaking under load deserves investigation but does not identify the source by itself.Inspect the bottom bracket and shell →

Geometry interpretation
What this geometry means
XS geometry
Riding position
The 495 mm stack is low relative to the 368 mm reach, giving the frame a performance-oriented, lower-front-end proportion with more potential for a stretched riding 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
The 70.8° head angle points to more stability-oriented steering geometry. Head angle is only one part of steering feel; fork offset, trail, wheel size and cockpit setup also matter. A 74 mm bottom-bracket drop places the rider relatively low between the wheels, which can add a settled cornering feel while reducing pedal clearance compared with a higher bottom bracket.
Archive context
Its trail of 61 mm sits toward the lower-trail end. Its stack of 495 mm sits toward the lower end. The chainstay of 408 mm sits somewhat shorter than typical.
S geometry
Riding position
The 520 mm stack is low relative to the 377 mm reach, giving the frame a performance-oriented, lower-front-end proportion with more potential for a stretched riding position. A 74.5° 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
The 71.9° head angle points to more stability-oriented steering geometry. Head angle is only one part of steering feel; fork offset, trail, wheel size and cockpit setup also matter. A 74 mm bottom-bracket drop places the rider relatively low between the wheels, which can add a settled cornering feel while reducing pedal clearance compared with a higher bottom bracket.
Archive context
The chainstay of 408 mm sits somewhat shorter than typical. Its stack of 520 mm sits somewhat lower than typical. The seat angle of 74.5° sits somewhat steeper than typical.
M geometry
Riding position
The 540 mm stack is low relative to the 386 mm reach, giving the frame a performance-oriented, lower-front-end proportion with more potential for a stretched riding position.
Handling tendencies
The 73° head angle points to moderate and balanced steering geometry. Head angle is only one part of steering feel; fork offset, trail, wheel size and cockpit setup also matter. A 72 mm bottom-bracket drop places the rider relatively low between the wheels, which can add a settled cornering feel while reducing pedal clearance compared with a higher bottom bracket.
Archive context
Its trail of 57.5 mm sits toward the lower-trail end. The head angle of 73° sits toward the steeper end. Its stack of 540 mm sits toward the lower end.
L geometry
Riding position
The 395 mm reach and 565 mm stack form a moderate road-bike proportion, balancing cockpit length with front-end height rather than pushing to an extreme race-low or endurance-upright shape.
Handling tendencies
The 73.5° head angle points to moderate and balanced steering geometry. Head angle is only one part of steering feel; fork offset, trail, wheel size and cockpit setup also matter. A 72 mm bottom-bracket drop places the rider relatively low between the wheels, which can add a settled cornering feel while reducing pedal clearance compared with a higher bottom bracket.
Archive context
The head angle of 73.5° sits toward the steeper end. Its stack of 565 mm sits somewhat lower than typical. Its trail of 57 mm sits somewhat lower than typical.
XL geometry
Riding position
The 404 mm reach and 590 mm stack form a moderate road-bike proportion, balancing cockpit length with front-end height rather than pushing to an extreme race-low or endurance-upright shape.
Handling tendencies
The 73.5° head angle points to moderate and balanced steering geometry. Head angle is only one part of steering feel; fork offset, trail, wheel size and cockpit setup also matter. A 72 mm bottom-bracket drop places the rider relatively low between the wheels, which can add a settled cornering feel while reducing pedal clearance compared with a higher bottom bracket.
Archive context
The head angle of 73.5° sits toward the steeper end. Its reach of 404 mm sits toward the longer end. Its stack of 590 mm sits toward the lower end.
Across the size range
From XS to XL, reach grows by 36 mm and stack by 95 mm, showing how the frame becomes both longer and taller through the published size range. The rear center stays essentially constant at about 408 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.
