|Is this a Dura ace cassette ?||PeterRider|

|I have a 12-21 cassette, 8-spd, weight 252g. Is this a Dura ace cassette ? I want to sell it, but also don't want to say it's dura-ace if it is not. |
On the cassette itself there is not the mention Dura-ace but only Hyperglide. I got it with Dura-ace wheels, well, I know this doesn't show that the cassette is Dura-ace too...

|What does the lock ring say? D/A 8 speed lock rings say Dura Ace although that doesn't mean the cogs are Dura Ace either. D/A cogs are a darker greyish color instead of chrome.|

|Shimano advertises their 12-23 9-speed as 159 grams. Why don't you advertise it as an 8-speed Shimano hyperglide?|
|apparently it is not that heavy...||PeterRider|

|I look on a shop website : http://www.schwabcycles.com/cgi/wc.dll?SCHWAB2~catalog~DETAIL~305 |
and I see : dura-ace 8spd 12-23 : 283g
and ultegra 8spd 12-23 : 280g
So I guess that the weight is not really the issue.
Too bad shimano gives only 9spd specs on their website, does anybody know where to get 8spd specs ?

|Take a magnet. If the magnet sticks to the cogs, it ain't Dura-Ace. If they don't, well, who knows? If they don't at least say Shimano on each cog, then I'd bet they are not D/A, either.|

|8 speed Dura-Ace was an all steel cogset. I'm pretty sure it wasn't a nonmagnetic alloy too.
The only distinguishing feature between Dura-Ace and 600 was the finish (darker on DA) and the lockrings (Dura Ace says "Dura-Ace" 600 says "HG Hyperglide").
