Does anybody else get annoyed by this? It's simple: a cog drives a cog, a chain drives a sprocket. All the bike mags call them cogs. What am I missing here?!!
Ps while I'm annoyed anyway, why has my font come out small? Who did this to me??!?!!!
I've always called it a sprocket, as when I used to bmx a "sprocket stall/slide" sounds way better than a "cog stall/slide" !
That journos are not engineers?
Only just human in some cases.
Oh, NOW it's the right size!!

I genuinely believe that when it comes to [u]bike[/u] journos we can upgrade that to 'most'

The cog that drives the sprocket that powers the interweb is broken... 🙂

No. I learnt mechanics on technic lego where the exact same parts could be cogs, sprockets or pinion wheels depending on what you mated them to.
Someone needs to tell all those charlatans selling "chainrings" and "chainwheels" (shimano iirc) about this too then. 😉
, u ok hun?
U need to chillax..

'Chainring' is fine by me, it's a bike specific word that refers to, well, 'chainrings'! 🙂
that 24 tooth cog with a chain around it has a very small hole in the middle.
Should I be calling my chain rings sprockets as well?
, u ok hun?
I will end you for that..... 👿
'a rose by any other name....'
But it's not a chainring: that would be better used to describe a ring made out of chain. It's a front sprocket. Or in the case of motorcycles, a pinion. 😉
I'm an engineer and I call them cogs. I also call vacuum cleaners Hoovers, and I call lunch dinner, and dinner supper, unless its a restaurant and I call dinner dinner.
wwaswas, I refer to my previous answer 😉
I've always felt that cassettes should be called 'evenly spaced sprocket clusters'.
Bet you call public address systems 'Tannoys' too, heathen? 😉

Now you're just being silly!! 😉
i used to call a spade a spade, but on closer inspection it turns out its a shovel.
It's a sprocket!
Shermer75, it must be so tiring being a beacon of correct mechanical nomenclature. I trust that you also also:
-know your spindles from your axles
-say Dérailleur not mech, and pronounce the double l properly.
-bleed your brakes from the reservoir or master cylinder not the lever
-say 'ferrule' not 'end cap'
-only refer to an allen key if its manufactured by Allen
-talk of 'chain bushing wear' not "stretch".
-have absolutely no adjustable wrenches in your home or workplace. 😉
Julianwilson yep, you're right, you got me there- I do none of those things. Sprockets and cogs though, it seems so obvious!!! Does it REALLY not annoy anybody else????
Cog is a generic term. A Pinion is a specific type or subset of Cogs i.e. as in Rack and Pinion steering. As is an idler. You don't have pinions in chain drive trains. I would say they are sprockets. But its just splitting hairs. On my first day as an Apprentice we were told there is no such thing as a Drill Bit. Its a Drill, as is the machine that drives it, but is preceded by antoher work like Pillar Drill, or Hand Drill, and if any of us were caught calling it a Drill Bit we go a good bollocking.
Despite knowing perfectly well that it's a sprocket, I call it a cog, because it's a nicer word to say. Cog. Cog.
Cog.

Just looked it up on Wikipedia (!) and apparently it's the [i]teeth[/i] that are called cogs, and what I was referring to as cogs are actually called gears. The teeth on sprockets are also called cogs. Hrumph.
Is this what being hoist upon ones own petard is?
See also....front forks. Or back shocker.
PCB board 😐
currentley giggling away at the monitor as the wharehouse lad looks at me like a t*^t... so whare douse a 1pc driver sit in this equasion is it a driver or a sprocket.... also on a belt drive would that then be a cog as not used with a chain or still sub catagorised at sprocket?
sorry.
Weirdly enough 'hoist by your own petard' means shot by your own ordinance- it's olde english!
Front forks and back shocker. Aaaaaargh!!!!
Belt drive = sprocket. What's a 1pc driver?

I was under the impression that belts went around pulleys. (Well they do on line shafts).
Wasn't the petard the charge in the mine placed under the enemies walls prior to effecting a breach? To be hoist by the petard was due to incorrect fuse length leaving insufficient time to retreat to a safe distance.
Sandwich I can't say if you're definitely right or not but that sounds like a much more convincing answer!! 🙂

Aah, but the belts here have teeth, which interlock with the teeth on the sprocket, hence sprocket! 😉

Duh - it's not "Sprocket or cog" - it's "Sprocket the dog" !
PAT testing!

Front cog, no chainring, rear sprocket, no cassette, ss cog? Doh!
