What the specifications mean
Electronic shifting removes the usual shift cable but adds a separate battery and controls, while the 330% 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 · 330% 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
420 geometry
Riding position
The 512 mm stack is low relative to the 370 mm reach, giving the frame a performance-oriented, lower-front-end proportion with more potential for a stretched riding position. A 75.5° 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 70.6° 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 stack of 512 mm sits somewhat taller than typical. The chainstay of 408 mm sits somewhat shorter than typical. The seat angle of 75.5° sits somewhat steeper than typical.
455 geometry
Riding position
The 525 mm stack is low relative to the 375 mm reach, giving the frame a performance-oriented, lower-front-end proportion with more potential for a stretched riding position. A 74.8° 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 71.6° 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 head angle of 71.6° sits toward the steeper end. The chainstay of 408 mm sits somewhat shorter than typical. Its stack of 525 mm sits somewhat taller than typical.
485 geometry
Riding position
The 543 mm stack is low relative to the 382 mm reach, giving the frame a performance-oriented, lower-front-end proportion with more potential for a stretched riding position. A 74.8° 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 72.5° 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 72.5° sits toward the steeper end. The seat angle of 74.8° sits toward the steeper end. Its stack of 543 mm sits toward the taller end.
510 geometry
Riding position
The 387 mm reach and 562 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. 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 72.9° 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 seat angle of 74.5° sits toward the steeper end. The head angle of 72.9° sits somewhat steeper than typical. Its reach of 387 mm sits somewhat longer than typical.
530 geometry
Riding position
The 394 mm reach and 580 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 72.9° 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

Handling tendencies
The 72.9° 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 seat angle of 73.5° sits somewhat steeper than typical. The head angle of 72.9° sits somewhat slacker than typical. Its bottom-bracket drop of 72 mm sits somewhat deeper than typical.
570 geometry
Riding position
The 409 mm reach and 619 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 72.9° 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 seat angle of 73.3° sits toward the steeper end. Its reach of 409 mm sits somewhat longer than typical. The head angle of 72.9° sits somewhat slacker than typical.
Across the size range
From 420 to 570, reach grows by 39 mm and stack by 107 mm, showing how the frame becomes both longer and taller through the published size range. Head angle also changes by 2.3° through the size range, so the manufacturer is not using identical steering geometry for every size.
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.
