What the specifications mean
Electronic shifting removes the usual shift cable but adds a separate battery and controls, while the 273% cassette range describes how much gearing is available. Hydraulic disc brakes shift routine service toward pad and rotor condition, fluid leaks and use of the correct bleed fluid. Carbon construction changes the inspection emphasis from metal-style dents and corrosion to impact damage, ripples and overtightened clamp areas.
Drivetrain
Electronic · 273% range
Shift-system battery state joins derailleur setup and sprocket compatibility as a troubleshooting variable.
Brake service
Hydraulic disc
Pad and rotor condition plus the correct bleed fluid are the primary service checks.
Frame material
Carbon / composite
Look for impact damage and clamp marks rather than metal-style dents or rust.
Wheel standard
700C · 622 mm
The label fixes rim diameter, not tire width or available frame and fork clearance.
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 levers should feel firm and return cleanly. Check for fluid around the levers and calipers, inspect pad thickness and contamination, and look for worn or bent rotors.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.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 507 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.
Handling tendencies
A 71.6° head angle combined with a 971 mm wheelbase points to more 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. 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 73.8° sits toward the more relaxed end. The head angle of 71.6° sits toward the steeper end. Its wheelbase of 971 mm sits toward the shorter end.
S geometry
Riding position
The 530 mm stack is low relative to the 378 mm reach, giving the frame a performance-oriented, lower-front-end proportion with more potential for a stretched riding position.
Handling tendencies
A 72.2° head angle combined with a 976 mm wheelbase points to moderate and balanced 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. 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 73.8° sits toward the more relaxed end. The head angle of 72.2° sits somewhat steeper than typical. Its bottom-bracket drop of 72 mm sits somewhat shallower than typical.
M geometry
Riding position
The 546 mm stack is low relative to the 384 mm reach, giving the frame a performance-oriented, lower-front-end proportion with more potential for a stretched riding position.
Handling tendencies
A 72.9° head angle combined with a 981 mm wheelbase points to moderate and balanced 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. A 70 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 bottom-bracket drop of 70 mm sits somewhat shallower than typical. Its trail of 58 mm sits somewhat lower than typical. The head angle of 72.9° sits somewhat steeper than typical.
ML geometry
Riding position
The 389 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.
Handling tendencies
A 73.5° head angle combined with a 980 mm wheelbase points to moderate and balanced 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. A 70 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. The seat angle of 73.4° sits toward the more relaxed end. Its reach of 389 mm sits toward the longer end.
L geometry
Riding position
The 394 mm reach and 582 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
A 73.8° head angle combined with a 990 mm wheelbase points to quicker-steering and more immediate 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.
Archive context
The head angle of 73.8° sits toward the steeper end. Its wheelbase of 990 mm sits toward the shorter end. Its bottom-bracket drop of 68 mm sits toward the shallower-drop end.
XL geometry
Riding position
The 402 mm reach and 610 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
A 73.9° head angle combined with a 1007 mm wheelbase points to quicker-steering and more immediate 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.
Archive context
The head angle of 73.9° sits toward the steeper end. Its bottom-bracket drop of 68 mm sits toward the shallower-drop end. Its wheelbase of 1007 mm sits somewhat shorter than typical.
Across the size range
From XS to XL, reach grows by 32 mm and stack by 103 mm, showing how the frame becomes both longer and taller through the published size range. The rear center stays essentially constant at about 410.5 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.
