That was my suspicion too, but the only alternative factor was that I stopped riding as soon as I sensed some looseness. I knocked on doors until I found an 8 mm allen wrench. I'm going to give it one more pop before writing it off. This bike has S&S couplers, so the left crank gets removed regularly. I probably just didn't tighten it enough the last time I reinstalled it.
I agree the XD 600 is a very reliable crank. But I live in a town with and ride a lot of dirt roads, and wet conditions (but much less since I retired and stopped commuting), so I have to take the crank apart a couple of times a year to throughly clean the middle and inner ring. At those times I end up cussing the hidden bolt and loose spacers. I have the Alpina dbl (48/34) sitting on my old Marinoni stage racing bike... in the basement, unused, but think the kind of riding I do on this bike calls for a triple. I have the DaVinci (actually made by White Ind) on both the Saluki and the tandem and really like them. At $220 plus rings, they are neither cheap nor crazy expensive. Until last year I never even thought about pinned rings but put them on the tandem and have been amazed at how well they shift. Tandems give notoriously poor front end shifting and a set of hi end rings really improved things.
