You're welcome. Just wanted to share my good fortune of stumbling upon this advice when searching for gearing alternatives as I have learned so much from this forum in all aspects of cycling. I had to try it because I just didn't want to abandon my Chorus compact. What a great crankset it is too as you know if you have one...smooth, dead quiet and not a hint of flex. I am sure the UT alloy CT Campy cranks are wonderful as well.
If anything the 38t Sugino ring is even more quiet then the 34t Campy inner that was on it. I was simply spending too much time in the outboard section of the rear cassette. I couldn't be happier with this inexpensive mod and easily reversible.
