I currently run a 50/34 Shimano 105 outboard bearing compact double on my cross bike. 110 BCD. I think, based on my usage, that I'll get more efficient use out of this crank changing out the chainrings for 48/36.
I've found two 48 tooth chainrings that fit the bill. One is a Sugino unramped and unpinned chainring available at a great many places, in the neighborhood of $35. The other is an older 5 bolt 110 BCD Shimano XTR for around $75.
My question is this: I've never used "plain" chainrings. I know that ramped/pinned are better for shifting, but is that XTR chainring over $40 dollars better performing? Will my shifting get all kludgy with a plain chainring. Bear in mind that I'm using STI shifters, so it doesn't exactly have all the crude adjustment capability of a friction shifter.
