Velopedia analysis
What the specifications mean
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 mixed-wheel layout uses different front and rear diameters, so tires, tubes, rims and spare wheels are not interchangeable end to end. The 227% cassette range describes the available gearing more clearly than the component-group name alone.
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 →
- BrakesIdentify the installed brake system before riding or ordering parts. Test every installed brake separately at walking speed, confirm it stops firmly and releases cleanly, then inspect its pads, braking surfaces and complete cable or hose path.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 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 →
