Speeds: Single
Simple, strong and low-maintenance—perfect for cruisers, commuters and BMX freewheel builds.
Gears: 22T × 1/8"
22 teeth give a lower/easier gear than 16–20T—best for easy starts, relaxed cadence, heavier bikes, kids’/utility builds, or rolling terrain.
1/8" chain interface = wide, durable tooth contact that resists skipping.
Model: SFW
ALTA’s Standard FreeWheel line—straightforward, durable, shop-friendly replacement across many SS bikes.
Size/Thread: 1.37" × 24 TPI (BSA/English)
The most common freewheel thread; threads directly onto the freewheel side of flip-flop hubs and other threaded single-speed hubs.
Not interchangeable with metric M30 × 1.
Type: Standard (Not 8-Key)
Uses a standard freewheel removal tool that matches the SFW interface (not the 8-key LM08 style).
Color: Brown
Protective brown oxide/phosphate-style finish for corrosion resistance and a vintage/classic aesthetic.
Brand: ALTA
Dependable aftermarket BMX/SS components with broad compatibility and solid value.
Body/Teeth: Heat-treated steel for wear resistance under SS torque.
Internals: Self-contained ratchet & pawls with internal bearing races (classic threaded-freewheel design).
Tooth Profile: 1/8" single-speed profile for strong chain seating and reduced skip.
Install: Clean & lightly grease hub threads → hand-start to avoid cross-threading → pedal torque self-tightens.
Removal: Fully seat the correct standard freewheel remover for SFW → turn counter-clockwise with wrench/bench vise.
Tip: Keep your 1/8" chain clean and within wear limits to maximize life and quiet operation.
Extra-easy gearing for comfort and hills; great for cruisers, commuters, utility and kid builds. Common pairings:
42 × 22 ≈ 1.91 : 1 – very easy starts, relaxed cadence
44 × 22 ≈ 2.00 : 1 – comfortable city cruising
46 × 22 ≈ 2.09 : 1 – gentle hills, steady pace
48 × 22 ≈ 2.18 : 1 – a touch faster on flats while staying easy
(Bigger front ring = faster; smaller = easier.)
Hubs: Any 1.37×24 TPI threaded hub, including flip-flop (install on the freewheel side).
Chains: 1/8" single-speed only (not 3/32").
Bike Types:
• Cruisers & choppers (beach cruisers, comfort/utility SS)
• BMX (threaded freewheel models & older/entry bikes)
• Commuter/Urban SS needing easier starts/hill help
• Track/fixie flip-flop when set up for 1/8" on the freewheel side
Brand examples (model/year dependent—confirm hub thread & chain width):
Cruisers: Electra SS, Firmstrong (Bruiser/Urban SS), Micargi (Rover/Tahiti SS), Schwinn Cruisers, Huffy Cruisers.
BMX (freewheel type): Mongoose (older/entry Legion & freestyle singles), Haro (older Freestyler & entry lines), GT/Dyno (heritage/entry), Redline (older/entry), Diamondback (’90s–’00s), Eastern (budget), Huffy/Kent/Magna (dept-store BMX).
