question on campy chainring width
I picked up a more then healthy supply of chainrings, all of which are 144bcd S.R. Japan,
And hiding in the pile was
one NOS Campagnolo 52t ring, the width of the teeth is 3mm, or a tad under 1/8
the sungino rings are 2mm
is this ring something special?
---------------------------------------------------------
update- now I know this is a track chainring.....

Which makes for a good opportunity to ask something which I've pondered for awhile: 
Why are track chainrings thicker?

good question, maybe because its a single speed, and the thinner teeth wear faster.
the little rear will wear out much faster.

Of course it's something special Mike, it's Campagnolo! 
All my Record road rings are about 1/8 thick. 3.6 mm or so. That's the main plate, however.

According to the Catalog 18 road rings are for chain 1/2x3/32" (2mm) and Track rings are for chain 1/2x1/8" (3mm). So it is possible you have a Pista ring.

I don't want to be a stickler on words but I true track bike is a fixed gear, not a single speed, therefore not only does the main ring have to be able to take the force of acceleration but also deceleration too. Structurally a thicker ring just makes better sense. Plus the chain tension on a track bike is way different than a bike with a derailleur which also causes more chainring wear.
