Speaking of greasing up, I was working on my exerciser when I thought, Hey you have never greased the roller on your tensioner. With that fresh on my mind I pulled the roller off the tensioner. Now I haven't had this bike more than a couple of months no matter what you guys think. That hydroelectric dam bolt, the one that goes through the cheap roller, is so corroded I'm amazed that the darn wheel will even turn. I slapped a lot of grease on it and then ordered one with a bearing.
