Velopedia analysis

What the specifications mean

Derived from the archived manufacturer recordHow Velopedia reads these specifications →

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. The 309% cassette range describes the available gearing more clearly than the component-group name alone. Hydraulic disc brakes shift routine service toward pad and rotor condition, fluid leaks and use of the correct bleed fluid.

Suspension setup Front + rear Fork and shock pressure, sag and rebound should be balanced and recorded independently.
Gearing 309% cassette range Calculated from the published 11–34-tooth sprocket span.
Brake service Hydraulic disc Pad and rotor condition plus the correct bleed fluid are the primary service checks.
Frame material Aluminum / alloy Dents and cracking around welds, pivots and loaded junctions deserve attention.

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 →
  • FrameLook closely for dents and hairline cracks around welds, the head tube and bottom-bracket area. Cosmetic scratches matter less than a change in shape or a crack line.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 →
  • SuspensionAsk when the fork and shock were last serviced. Check the stanchions for damage, look for oil at the seals, cycle both units through their travel and test the suspension pivots for play.Evaluate the suspension →
  • DrivetrainShift through every gear under light load and measure chain wear. Confirm that the shifter, derailleur, chain and cassette belong to the same 9-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.Check wheels and tires →
