I got the Journeyman worked on the other day. I had a good week of commuting but this week the bike has shifted terribly. It has shifted the chain off the outside of the crankset twice on the ride. it has also jumped on the rear cassette. I am not sure if the cassette is worn out. this is the second chain on the bike. I am tempted to put the new cassette i have waiting to give me a better ride. I am not sure if it is an adjustment issue or the piece is worn out.
