Hey folks

I just got a fixed conversion used. The only thing I don't like so far is the ratio; 52:16 is a little steep for me when there are steep hills. However, the cranks on it are spiderless Sugino's. I've tried googling, and searching the sugino website and haven't found any information about them or what my options are for replacement chainrings. I know I could just get a bigger cog, but it's a kludge, and I'd prefer to not mess with the loc-tite and stuff now that it's all set. Has anybody ever heard of these spiderless Sugino's? If so, what kind of rings should I use?

Thanks a lot.
