Alloy / steel track cogs and chainrings

[User]

 

[S-Express]

Marginal (and completely irrelevant) weight advantage for alu. We've currently got a Suzue stainless cog on one wheelset and a Halo steel on the other, although neither is for road use. Unless you want to shell out for an absurdly-expensive EAI alu track cog, then just go for steel.

Steel is also an alloy.

 

[Yellow Saddle]

A cog is a single tooth on a wheel.

Steel sprocket on the back but an aluminium chainring.

 

[fossyant]

Steel sprocket due to aluminium one would wear quickly. Alloy chain ring though

 

[Yellow Saddle]

Yes but it is also the whole collection thereof.

No, it is not.

So what should I get?

I'm going for steel.[/QUOTE]

Pretty much anything will do.

[QUOTE 4940496, member: 1314"]Actually, why?[/QUOTE]

Aluminium is softer and has been said loads more expensive.

Mixing your metaphors again, are you?

I cry selective quotation.

Cambridge diction

Merriman-Webster dictionary.

Then, the all authoritative Urban Dictionary explaining point 2 in the Merriman-Webster definition.

Sprocket: a wheel with many cogs which interface with a roller chain.
Gear: A wheel with many cog which interfaces with another wheel with many cogs.

Cog replacement is a common engineering procedure where the broken cog (tooth) is removed, and a new one put in its place with the aid of a stud, a little bit like a dental procedure. If you walk into that engineering shop with your broken cogwheel (gear) and ask for a cog replacement, you 'll get one tooth replaced. If you ask for a gear replacement, they'll walk to the rack and give you an entirely new cogwheel.

Who knew that the word cog could be so controversial....

Hang around the riders' D at any velodrome for long enough and you will hear 'sprocket' and cog' on a regular basis, both in reference to the same thing..

For the rear, yes.
