So I take the bike the on first ride to work and guess what happenns? C’mon, guess. If you read the title and said, “you got towed” you would be correct. After about 20 miles of test rides including 5 into work the sprocket set screws and key managed to work themselves out by Grant and Oracle. At least there was a turn off where i could pull over and figure out what was going on. What was going on was they key came out and the shaft just turned inside the sprocket. Ugh. one thing i did not have tools to fix the problem.
