Thanks, Peter. The 52-38 combo is one I've alway liked on doubles, probably because it is about alll a short cage RD will handle with a 26 or 28T large cog on the rear (a Simplex Crtierium or SLJ handles this better than a Campy NR). The ability to use a 52-38 is one reason I've always liked Stronglight and Zeus better than Campy NR/SR.Since I'm now in Houston, which is pretty flat, I'm relactant to go to a smaller outside ring. The 28T ring is intended as a granny, that will only be used on hills not encountered in the immediate Houston area. Would it do any good at all to go to a 32T inner, or is reducing the gap between middle and outer the only way to improve things?
