Your changes apply to this calculation. The archived build stays unchanged.

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.

Cadence (RPM) Speed units

Full used-bike inspection guide →

Frame and fork

Inspect the frame and fork →

Archived: Frame: Aluminum · Fork: · Unicrown

Look for dents or shape changes and inspect the edges of welds around the head tube, bottom bracket, seat cluster and suspension mounts for hairline cracks.

Drivetrain

Check drivetrain wear →

Archived: Group: Cruiser Mix · Shifters: Shimano Revo twist · Front derailleur: Shimano TX-31 · Rear derailleur: Shimano TX-31 · Crankset: Electra Custom Alloy · Bottom bracket: Sealed cartridge · Cassette: Shimano · Rear cogs: 14 - 28 teeth · Chain: KMC Z51

Shift through every available gear under light load. Hesitation, skipping or inconsistent indexing can reflect wear, damage, poor adjustment or mismatched replacement parts.
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: Linear Pull brakes, Alloy levers

Inspect pads, cables and housings, then examine both rim braking surfaces for concavity, cracking or heavy wear. Confirm each caliper returns and centers correctly.

Wheels and tires

Check wheels and tires →

Archived: Wheel size: 26" wheels · Rims: Alloy, 36-hole · Hubs: Alloy · Front tire: 26 x 2.125" Retrorunner

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.

Controls and contact points

Archived: Headset: 1" steel threaded · Handlebar: Electra Bullhorn · Stem: Alloy Classic · Seatpost: Classic Alloy Pillar · Saddle: Electra Comfort w/ Elastomer Springs · Pedals: Resin Barefoot

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.
