After a frightful lockring experience I got myself a new Dura-Ace from Harris Cyclery. I figured while I was down there I could change my gear ratio since the 47x16 with 165mm cranks gave a gain ratio of 6.0 (77.5 gear inches). I dropped that to 47x18x165mm which gives a much easier 5.3 gain ratio(68.9 gear inches).

I picked up some Phil Wood waterproof bearing grease; that stuff is blue and I applied it liberally! Blue!

So anyway, the new gearing is noticeably easier going up hills and also my legs are spinning MUCH faster on the downhills. So far it seems like a sweet ratio!

So.. Yah, I got a Rockwerks 18 tooth cog, and Dura-ace lockring. I rotafixed the cog then tightened the heck out of the lockring. I rode a few miles, and stopped at the top of a hill. I tried to tighten that lockring again but man was it on there tight.. Good signs.. I also did a number of skids with no slippage; good signs!

OK.. so for some pics:
