Thx, I'll get one of those tools, and put a decent cog and lockring on my "to buy" list.
I looked at it today - turns out the chainring bolts were loose. A total surprise, as I've never seen this in my 35+ years of cycling. And I know I tightened them when I installed the short stack bolts. I've even got the correct tool for the back. I guess riding fixies puts a reverse stress on these bolts.
