A couple of years ago, there was an issue with quality control on the IRD's. The issues were addressed quickly and are no longer an issue. About that time I purchased a 7spd. It is quiet and works well. Freewheels either work well or not. When they do, very few say anything but when they don't......
I have not used KMC chains but do run a SRAM 8spd. Looks nice, works well.
BTW, The IRD was used on my 83 Colnago. I have since changed to a near NOS Regina I picked up and I cannot believe how well it shifts! it is a CX/CXS or something close. My drive train is Campagnolo Super Record.
