It rained in my commute last Thursday. I cleaned (hosed off and dried) the bike and lubed the drivetrain. The following Friday, and Saturday, the bike did not show any signs of trouble. I rode over 80 miles between those two days. Sunday, I was going to get the bike ready for Monday's commute when I noticed, the crank would only pedal backwards. I took the chain off the chainrings to isolate the problem and see if it is the bottom bracket. Sure enough it is. This is an old steel bike (circa 1989), with Suntour Sprint cranks and bottom bracket. Have any of you had this type of problem? Please describe the damage inside the BB, if you have had the chance to work on it. Thanks.
