2. Cogset - Wikipedia

   en.wikipedia.org/wiki/Cogset

   A freewheel can be removed from the hub with one of the many specific freewheel removal tools that engages a spline or set of notches on the outboard end of the freewheel. Removal often requires considerable effort due to the large torque that tightens the freewheel during pedaling, and some freewheels cannot be removed intact. Future removal ...

3. Freehub - Wikipedia

   en.wikipedia.org/wiki/Freehub

   Freehub vs freewheel hub. The freehub concept answers several drawbacks encountered with the freewheel design: Freewheels are threaded onto an axle hub, using conventional right-hand threads. As the bicycle rider pedals, the freewheel is continuously kept tight, as chain torque is in the right-hand direction. This becomes a problem when the ...

4. Fixed-gear bicycle - Wikipedia

   en.wikipedia.org/wiki/Fixed-gear_bicycle

   Usually, the rear hub is the best component on which to perform chainline adjustments, especially on threaded hubs. If a track hub is used, it is better to operate on the bottom bracket or - for minor shifts - on the crankset. The same occurs if a flip-flop hub is used, because the chainline should be the same in both sides (freewheel and fixed ...

5. Flip-flop hub - Wikipedia

   en.wikipedia.org/wiki/Flip-flop_hub

   A standard single-speed BMX style freewheel can be used on the track threads of the hub. Because of the stepped down lock ring threads, not as many threads of the freewheel engage the hub threads as they would if it were threaded to a freewheel thread, however, this is not a problem since the same number of threads is sufficient to secure a ...

6. Locking hubs - Wikipedia

   en.wikipedia.org/wiki/Locking_hubs

   The hub is a component where the wheel is directly mounted to, and is outside the axle. The benefits of unlocking hubs for normal road use are mainly found in increased fuel efficiency . When the front hubs are locked, even if no power is sent to the front axle (by means of a transfer case ), the turning of the wheels will still spin the front ...

   Cluster: a bicycle cogset, either a freewheel, or cassette; Cogset: the set of rear sprockets that attaches to the hub on the rear wheel; Cone: holds bearings in place, pressed against the cup; Cotter: pin for attaching cottered cranks; Coupler: to connect tubing together; Crankset or chainset: composed of cranks and at least one chainring

8. Front freewheel - Wikipedia

   en.wikipedia.org/wiki/Front_freewheel

   The Shimano Front Freewheel (FFS) was a proprietary bicycle drivetrain design of the 1970s that placed a freewheel between the pedal cranks and the front chainrings – enabling the rider to shift gears while coasting. [2] FFS rear freewheel is different than a standard freewheel because it's "stiff" with more friction than a normal rear freewheel.

9. Single-speed bicycle - Wikipedia

   en.wikipedia.org/wiki/Single-speed_bicycle

   The simplest conversion uses the existing freewheel/cassette and crankset, the chain being cut to fit the desired gear ratio. However this retains unnecessary weight and the chainline will most likely not be perfect. A more thorough conversion will involve replacing the freewheel with a single-speed one, and re-dishing the rear wheel.
