Velopedia analysis
What the specifications mean
Hydraulic disc brakes shift routine service toward pad and rotor condition, fluid leaks and use of the correct bleed fluid. On the alloy frame, dents and hairline cracks around welds, pivots and heavily loaded junctions matter more than cosmetic scratches. A threaded bottom bracket still requires the correct shell width, thread standard and crank-spindle interface before replacement.
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.
Bottom bracket
Threaded interface
Shell width, thread standard and crank-spindle interface still require confirmation.
Published weight
9.37kg (20 lb, 10.5 oz)
Frame size, pedals, tire setup and production substitutions can change the measured result.
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 →
- DrivetrainShift through the full range under light load, measure chain wear and inspect the cassette or freewheel teeth. Skipping or hesitation can indicate wear, poor adjustment or mismatched parts.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 →
