Hey,

I've got some sugino single ring bolts and have a question. The bolts are plenty long enough but the nuts are only as long as my spider, so they don't protrude into the ring at all.

I was always under the impression that you wanted the ring to be somewhat supported by the nut (though obviously it needs to be short enough to tighten down).

Is my current setup fine?

Thanks.

Assuming the bolts are tightened enough and you're just using the bike to cruse around the block it'll be fine. But if the backing nut doesn't go through both the spider and chainring itself it might be harder to install centered properly and could be prone to some movement that would put you chainring out of round. chainring bolts are cheap enough to get the right ones
