Granted, the mode of transport was not ideal, but last week I laid my Schwinn MTB in the back of my pickup to take with me for a recreational ride with a friend. Naturally, I had to lay it over on the left side, which put a sidewise pressure on the left crankarm and pedal. (Spare me any nose in the air hoopla about the department store bike, please. It fits me perfect, so it's my casual recreational ride that I don't feel like I have to chain down every moment).
The buddy and I took in the city bike path and several miles of commuter infested campus traffic for a great ride on sunny fall day. My bike is presently stashed at my office.
After parking it in the corner, I noticed a ring of black grease had oozed out around the BB seal. Then, after getting home I took a good look at my Specialized in the carport. The BB is clean and dry.
So ... what might I consider here as the culprit on the Schwinn? I've never been into the BB for maintenance purposes, so I don't know if there are rubberized seals involved, or just a tight fitting metal washer that serves the capping purpose.
Any insight will be appreciated.
