My 1987 road bike has the dreaded BioPace chain rings; not knowing any better because I've been on a mountain bike for the last 15 years, they seem fine to me. But I'd like to try convention chain rings, so that I can A/B them with the BioPace.

Here's the question: what brands and models of chain ring can I use with my Shimano 105 cranks? Between the progression from 6-speed freewheels (which is what mine has, with indexed 105 shifters front and back) to 7- and 8-, and now 9- and 10-speed; Shimano's change from Uniglide to Hyperglide; different chain widths; and the possible incompatabilities between 105, 600/Ultegra, and Dura Ace ..... I'm really, really, confused.

Thanks.
