Original size / build

Gears Drivetrain

Front teeth Smallest rear teeth Largest rear teeth

Use up to three front tooth counts, separated by /. For one rear sprocket, enter the same count twice.

Rear tire

Rear tire marking

Apply the marking on your rear tire or edit its dimensions below. Older or fractional inch sizes need the ISO marking (e.g. 37-590).

Rim diameter (BSD, mm) Tire width (mm)

For 32-622, width is 32 mm and rim diameter is 622 mm. Use the rear tire on mixed-wheel bikes. Leave both fields empty to compare ratios only.

Frame and fork

Inspect the frame and fork →

Archived: Frame: TIG-welded · Fork: · Alloy, unicrown crown

Inspect the complete frame for cracks, dents, distortion, heavy abrasion, suspicious paint differences or evidence of a previous repair.

Drivetrain

Check drivetrain wear →

Archived: Group: Commuter Mix · Shifters: Shimano Alfine Rapidfire Plus · Crankset: RMB RM-P42 Alloy Arm, 42 teeth · Bottom bracket: TH BB-7420 · Cassette: Shimano Alfine · Rear cogs: 8-speed internal, 18 teeth · Chain: KMC

Shift the hub through its complete range using the correct procedure. Check cable or electronic actuation, axle security, hub-shell condition and any sign of lubricant leakage.
Measure chain wear with a compatible gauge and inspect chainring, cassette or freewheel teeth. A new chain does not rule out wear in the remaining drivetrain.
Turn the cranks slowly, feel for rough bearings and check for side-to-side play. Inspect crank arms, chainring bolts and pedal threads for looseness or damage.

Brakes

Inspect the brakes →

Archived: Brakes: Shimano M416 Mechanical Disc brakes, Shimano BR-M421 levers

Check both cables and housings for corrosion, fraying or drag. Confirm each caliper releases cleanly, then inspect pad thickness, rotor wear and rotor alignment.

Spin both wheels and watch for side-to-side and vertical movement. Check spoke tension, rim condition and hub play.
Inspect both tire casings for cuts, cracking, plugs, bulges or exposed threads and confirm the installed sizes are safe for the rims and available frame and fork clearance.

Archived: Headset: FSA · Handlebar: RMB Zero10 Bar 620mm · Stem: RMB 7-degree flip/flop · Seatpost: RMB, 31.6mm diameter · Saddle: Rocky Mountain · Pedals: VP 349S Alloy Body & Steel Cage

Apply the front brake and rock the bike to check for headset play or notchiness. Inspect the stem, handlebar and clamp zones, then confirm every fastener and control is secure.
Check that the seatpost moves for adjustment and that the saddle, post and clamp hold securely without cracks, severe corrosion or damaged hardware.
