Back to the chain ring, are you 100% sure it's genuine? The reason I still have doubts is that the burs on every arm don't seem to me representative of Sugino quality. Furthermore, would the road chain ring teeth be sloped at all to facilitate shifting? As you can probably see from my OP, these teeth don't have any slopes. They are very much like track chain ring teeth, just 3/32".
Back in that time there wasn't such thing as profiled teeth or ramps. The burrs would take all of 30 seconds to clean off and won't affect function in any way. Furthermore once fitted you'd never know. Looking at other features it not only looks legit but a quality item. The stamping looks genuine and I would have no doubts about this item.
Again, it's strong thing to seek to discredit someone else based upon poor research and uninformed opinions. The problem I have is that had I not have seen this thread the seller would have had a strike against him, paypal would have found favour with you because they wouldn't know !! BAN ME NOW FOR SWEARING !! and side with buyers almost 100% of the time and yet another bunch of self credited experts would have used this thread as fact and furthered disinformation.
It's ok not to know, just ask questions and be patient. Making assumptions by mob proxy isn't cool and never make decisions based on anything other than fact.
