Velopedia analysis
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. Electronic shifting removes the usual shift cable but adds a separate battery and controls, while the 520% 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.
Used-bike inspection
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.

Geometry interpretation
S geometry
The 594 mm stack is tall relative to the 420 mm reach, pointing to a more upright front-end position rather than an especially long, low cockpit. Its 76° effective seat angle places the seated rider relatively forward, a layout that generally helps keep body weight centered on steep climbs.
A 65.9° head angle combined with a 1148 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.
Its reach of 420 mm sits toward the shorter end. Its stack of 594 mm sits toward the lower end. Its wheelbase of 1148 mm sits somewhat shorter than typical.
M geometry
A 450 mm reach paired with 604 mm of stack gives this size a moderate frame proportion: roomy enough when standing without pushing strongly toward either a very low or very upright front end. Its 76° effective seat angle places the seated rider relatively forward, a layout that generally helps keep body weight centered on steep climbs.
A 65.9° head angle combined with a 1184 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.
Its stack of 604 mm sits toward the lower end. Its wheelbase of 1184 mm sits somewhat shorter than typical. Its bottom-bracket drop of 40 mm sits somewhat deeper than typical.
L geometry
With 480 mm of reach and 618 mm of stack, the frame has a relatively long, low proportion that should leave plenty of room when standing and put the front end toward the lower side of modern mountain-bike fit. Its 76° effective seat angle places the seated rider relatively forward, a layout that generally helps keep body weight centered on steep climbs.
A 65.9° head angle combined with a 1223 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.
Its stack of 618 mm sits somewhat lower than typical. Its bottom-bracket drop of 40 mm sits somewhat deeper than typical. Its wheelbase of 1223 mm sits somewhat shorter than typical.
XL geometry
With 505 mm of reach and 645 mm of stack, the frame has a relatively long, low proportion that should leave plenty of room when standing and put the front end toward the lower side of modern mountain-bike fit. Its 76° effective seat angle places the seated rider relatively forward, a layout that generally helps keep body weight centered on steep climbs.
A 65.9° head angle combined with a 1264 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.
Its bottom-bracket drop of 40 mm sits somewhat deeper than typical. Its trail of 120 mm sits somewhat lower than typical. The chainstay of 442 mm sits somewhat longer than typical.
From S to XL, reach grows by 85 mm and stack by 51 mm, showing how the frame becomes both longer and taller through the published size range. Chainstay length grows from 435 to 442 mm across the range. That size-specific rear-center strategy helps the larger frames grow at both ends instead of adding all of their length ahead of the bottom bracket.
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.
