Gearing

Lower gears help on climbs. Higher gears suit higher speeds.

Speed unavailable: wheel or tire size is missing or unclear.

Add your rear tire size to calculate speed

How it works

Ratio = front teeth ÷ rear teeth. Hub gears also include the hub’s internal ratio. A 400% range means the highest ratio is four times the lowest.

Speeds are estimates from tire size and pedal cadence. Actual speeds vary.

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

Gear, dimension and cadence changes update results automatically.

Full used-bike inspection guide →

Frame and fork

Inspect the frame and fork →

Archived: Frame: 6061 Aluminum · Fork: SR Suntour M3010-Al 50mm

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.

Suspension

Evaluate the suspension →

Archived: Fork: SR Suntour M3010-Al 50mm

Inspect the fork stanchions for scratches or coating wear, look for oil or dirt rings at the seals, and cycle the fork through its travel while checking for binding or bushing play.
Ask for dated fork-service records. A clean exterior does not establish the condition of internal seals, oil or bushings.

Drivetrain

Check drivetrain wear →

Archived: Shifters: Shimano Revo · Front derailleur: Shimano Tourney · Rear derailleur: Shimano Tourney · Crankset: Suntour XCC 42/34/24t · Bottom bracket: Sealed Cartridge · Cassette: Shimano Hyperglide 14-34t · Rear cogs: 3x7 Speeds · 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

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

Controls and contact points

Archived: Headset: 1 1/8" Threadless · Handlebar: MTB Riser · Stem: Alloy · Seatpost: Alloy Micro Adjust · Saddle: GT MTB · Pedals: GT Slim Line

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.
