Lots

Took off at about 5:30. Got to the Lake Street bridge that crosses the greenway (less than half a mile from my house) and there was a cyclist down right under the bridge. Others were stopping also. A tri guy had seen him hit the asphalt saying, "he went down hard". The crack in his helmet and drooping shoulder validated his claim. I spent a good half hour there trying to help. Another group of cyclists also stopped and were very very kind and did most of the helping. The tri guy went home and got his own car, then came back to give the guy a ride home (total stranger). The plan was to pick him up at Punch Pizza, maybe 1000 - 2000 feet away. During this time the crash guy got a hold of his wife, who was coming to pick him up. By the time we got him to Punch he was feeling worse. There's a fire station across the street from Punch. The tri guy arrived and drove him to the fire station, where we got him attended to. Wife got notified of the change of venue. My diagnosis is a broken clavicle and a slight concussion. I left with the group of cyclists who had stopped to help and rode with them on a loop out through Opus, along Baker and home on Cedar Lake Rd. Real nice group of guys. We mixed it up some. 25/18.9

I've been complaining about the fast goodlookin' bike's complaining. I still keep getting a knock coming from the bb. I cleaned her up real good and replaced the bb, but I still get the knock. The only thing left it could be is the rear hub, or freewheel. I already replaced the cassette and chain. Tonight I put a different wheel on her and she went silent for the entire ride. So, now I've narrowed it down. It really can only be the rear hub or freewheel. Problem. I've never taken a freewheel off, let alone taken it apart. Tonight was the night!

Cleaned everything up, including that little rubber gasket on the inside of the ratchet springs (watch them they fall out easily), and put it all back together. NO PARTS LEFT OVER!
