Gearing

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

Pedal cadence

RPM

Speed units

RPM = pedal turns per minute.

All published sizes42/34/24T · 11–30T · 8-speed

Estimated speed At 90 RPM Lowest gear5.5 mph Highest gear26.4 mph

Uses front tire 26×1.9; rear size isn’t listed.

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.

Full used-bike inspection guide →

Frame and fork

Inspect the frame and fork →

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

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: Mountain Mix · Shifters: Grip Shift Neos · Front derailleur: Shimano Alivio top-swing, top-pull/clamp-on 31.8mm · Rear derailleur: Shimano Alivio · Crankset: Shimano Alivio, 24/34/42 teeth · Bottom bracket: Shimano BB-LP27, 110mm spindle · Rear cogs: 8-speed, 11 - 30 teeth · Chain: KMC IG-31, 1/2 x 3/32"

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: Tektro 823A linear-pull brakes, Tektro 381A 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: Sun Rims Z-19, 32-hole · Hubs: Front: Formula OV 31, Rear: Formula OV 32 · Front tire: 26 x 1.90" Maxxis Worm Drive

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 1/8" threadless Aheadset STS · Handlebar: Kalloy Riser 6061 butted · Stem: Kalloy aluminum · Seatpost: Polygon PM-780, 26.8mm diameter · Saddle: Velo VL-313 · Pedals: Wellgo LU-955A w/clips & straps

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.
