chainwheel

For clarity in communication the generic term chainwheel is often used.

Pedersen also received patents for a chainwheel and bottom bracket combination and lightweight pedals.

By combining these two materials, you get a chainwheel which is lighter than an all-steel construction but is more durable than the traditional all aluminium rear sprocket.

Fixed-gear bicycles (without a freehub) use the momentum of the bicycle and rider to keep the chainwheel turning even if the rider makes no attempt to pedal in a circular motion.

The pedals turned, the wheels spinned, but nothing whatever moved between the chainwheel and the Sturmey Archer cog . . . Omally's bicycle Marchant did not have a chain.

Bicycle cranks have dead centres at approximately 12 o'clock and 6 o'clock where simple pushing down of the pedal will not turn the chainwheel, but the rider's leg is able to apply tangential force at the pedal to overcome it.

Even a small difference in link size or consistency can cause undue wear on the chainwheel and/or cause the chain to jump off the windlass when the winch is operating, particularly during payout, a runaway condition sometimes referred to as "water spouting" should it occur at high speed.
